Hiking the Grand Balcon Nord in Chamonix

Last Updated on April 29, 2026 by Charlotte

The Grand Balcon Nord is one of the most incredible trails in Chamonix. Along the trail, you’ll see the Mont Blanc massif filling the skyline, the Bossons Glacier tumbling down to your left, and one of the most photographed views of the Mer de Glace waiting for you at the end.

In this guide, I’ll walk you through what to expect on the trail, how to choose your direction, how to handle the cable car reservation logistics that catch a lot of visitors off guard, and the practical details that will make your day go smoothly.

Hiking the Grand Balcon Nord Step-by-Step

The Grand Balcon Nord hugs the mountainside high above Chamonix, with no scary scrambles or descents along most of the route.

Starting from Plan de l’Aiguille

Stepping out of the cable car at Plan de l’Aiguille is one of those moments that genuinely earns the cliché, because the Bossons Glacier tumbles down the mountainside directly across the valley, the Aiguille du Midi spire reaches up behind you, and the whole jagged skyline of the Mont Blanc massif fills the view in every direction.

The trail itself starts immediately and is well-maintained, traversing the mountainside at a steady, gentle grade. You can actually look around and soak in the scenery without having to constantly watch your footing, which, after some of the more technical alpine trails in this region, is a real treat.

Side Quest to Lac Bleu

About 1.5 km in (a little less than a mile), you’ll reach a fork with a small sign pointing uphill toward Lac Bleu. What makes this lake feel genuinely hidden is that you can’t see it from Plan de l’Aiguille, and without a map, you might walk right past the junction and never know what you missed.

The climb up takes maybe 20 minutes. When we finally reached the lake, my jaw was on the floor again. The water was a deep aquamarine, and in the still moment we arrived, the surface was so perfectly reflective it was like a mirror. We had it almost entirely to ourselves.

The route back down to the main trail led us through more snowpack alongside a babbling glacial stream surrounded by wildflowers.

It felt like a mini adventure within the adventure, picking our way across snowfields, following the sound of rushing water, and discovering hidden pockets of alpine beauty that aren’t on any signpost.

Traversing the Balcon

Back on the main trail and continuing toward Montenvers, the character of the hike begins to shift. Chamonix is a mecca for trail runners, and roughly half the people we encountered out here were running rather than hiking.

There’s something infectious about it, watching people move through this kind of landscape with that much flow and freedom. We found ourselves alternating between walking the inclines and running the flats and gentle descents, slamming on the brakes whenever a waterfall appeared on the mountainside, or the clouds parted to reveal the valley far below.

The mountain also reminds you of its raw power along this stretch. We passed several spots that had clearly seen recent avalanches or rockfalls. There were pine trees snapped clean off at their bases where boulders had rolled through, some massive rocks even split in two!

It’s a humbling thing to walk through and makes you feel small in the best way.

Signal Forbes and the Boulder Field

As you continue toward Signal Forbes, the trail climbs a small ridge, and the landscape transitions into what feels like a boulder field.

The rocks aren’t huge, but they dominate everything around them. There’s little vegetation, just weathered stone scattered across the mountainside like something carved by giants. This rocky stretch is the greatest uphill push of the trail, but you’re rewarded by the view from Signal Forbes at the top.

It’s not a scramble, but there are spots where you have to hop from rock to rock, which is the section of the trail most likely to slow you down if balance or knees are a concern.

The Final Stretch to Montenvers

Past the boulder field, the trail begins its descent toward the Mer de Glace, and this is where you get one of the most photographed views on the whole hike, with the sprawling river of ice spreading out below you.

The descent itself is a series of switchbacks, and we let ourselves run most of this stretch because there was nothing new to slow down for.

If you’re hiking with someone whose knees are a concern, this is also the part of the trail where trekking poles will earn their keep.

Things to do at Montenvers

Once you reach Montenvers, you have a decision to make: head straight back to Chamonix on the cogwheel train, or extend the day with the gondola down to the Mer de Glace Ice Cave, or lunch on the terrace of the Refuge du Montenvers. We did the ice cave on a separate day because, as we’ll cover later, the time math doesn’t really work to do everything at once.

But here’s one last thing I’ll say about the Mer de Glace: I genuinely think you get a better view of the glacier from the Grand Balcon Nord than you do from the Montenvers observation deck. Up on the trail, you’re seeing the whole river of ice in its landscape context, with the surrounding peaks framing it. From the deck, you’re looking at it from a more limited angle. So if you have to skip the ice cave, you haven’t actually missed the view of the glacier. You walked past it for an hour.

Which Direction to Hike the Grand Balcon Nord

The Grand Balcon Nord is a point-to-point trail, which means you have a real decision to make before you head out: do you start at Plan de l’Aiguille and walk down to Montenvers, or do you start at Montenvers and climb up to Plan de l’Aiguille? It’s the same trail either way, but the experience is dramatically different depending on which way you go.

If you can only do the Grand Balcon Nord once, and you’re a casual hiker, do the downhill. If you’ve got more time and the legs, and you’re reasonably fit, the uphill version is the more dramatic experience for serious hikers.

Easiest Hiking Direction

Our recommendation is to hike from Plan de l’Aiguille down to Montenvers. This is the easier direction by a meaningful margin because you’ll take the cable car up to do most of the elevation gain in a 10-minute ride, then walk down ~700m gradually over the course of the hike. The grade is gentle enough that you can actually look around and soak in the scenery without grinding through a climb.

Harder but More Beautiful Hiking Direction

Hiking from Montenvers up to Plan de l’Aiguille means the Aiguille du Midi spire and the Mont Blanc massif are directly ahead of you the entire time, which is genuinely dramatic. In the downhill direction, those views are mostly behind you, and it’s a bit of a shame to have the Aiguille du Midi at your back when it’s one of the most striking peaks in the Alps. You’ll find yourself turning around often, and you’ll want to.

How to Get to the Trailhead

Here’s where the Grand Balcon Nord gets a little tricky: you can’t just drive up and start walking. Both ends of this trail are reached by mountain transport: a cable car on the Plan de l’Aiguille side, and a cogwheel train on the Montenvers side.

Plan de l’Aiguille (via the Aiguille du Midi Cable Car)

The Aiguille du Midi cable car leaves from central Chamonix town and climbs to Plan de l’Aiguille at 2,317m in about 10 minutes.

From there, you can either get off and start hiking, or continue up to the summit at 3,842m first (highly recommended if you have time). We have a full Aiguille du Midi guide covering that experience.

Quick note on ticket pricing for Plan de l’Aiguille:

• As of summer 2026, a round-trip ticket from Chamonix up to Plan de l’Aiguille only (skipping the summit) is €24 for adults and €20.40 for children and seniors.
• If you want to do the summit and the hike, there’s a “Hiker” ticket for €57 that takes you up to Aiguille du Midi at 3,842m, then lets you descend to Plan de l’Aiguille to start the trail, but this one has to be purchased at the ticket counter, not online.
• The standard summit round-trip runs €59.90 to €81 depending on the season. If you’re already planning multiple lifts during your trip, the Mont Blanc Multipass usually pays off after just two big excursions.
• You can check current rates and book directly on the official Aiguille du Midi site.

Aiguille du Midi Cable Car Reservations

As of 2026, every visitor must reserve a time slot for the Aiguille du Midi lift, including Mont Blanc Summer Multipass holders. Timeslot reservations are free, but they fill up, especially the morning slots in good weather.

I suggest that you aim for the earliest morning slot you can get. Mont Blanc tends to cloud over as the day goes on, and morning gives you the clearest views and the freshest legs for the hike. You can book both your lift ticket and your timed entry reservation online at the official Aiguille du Midi website.

Montenvers (via the Cogwheel Train)

The Montenvers train runs from its own little station next to the main Chamonix train station up to Montenvers at 1,913m, in a 20-minute ride aboard the famous little red cogwheel train. They do not take reservations, so you just show up, buy a ticket, and go.

Quick note on ticket pricing for the Montenvers Train:

• As of 2026, a return train ticket from Chamonix up to Montenvers and back is €31.50 for adults and €26.80 for children and seniors.
• If you want to add the gondola down to the Mer de Glace ice cave plus the Glaciorium museum, the bundled “Voyage Mer de Glace” ticket is €49.70 for adults and €42.20 for kids/seniors.
• You can check current rates and book directly on the official Montenvers Mer de Glace site.

The trailhead is well-marked from the Montenvers station, and you’ll spot the Mer de Glace observation deck right away if you want a quick photo before setting off.

The Mont Blanc Multipass

If you’re using both ends of this trail, the Mont Blanc Multipass is genuinely worth it. It covers the Aiguille du Midi cable car, the Montenvers train, and most other lifts in the valley, and it pays off after just two big excursions. We used ours for this hike, and it made the whole logistics piece simpler.

Best Times to Hike the Grand Balcon Nord

The trail is officially open from late June through mid-September, but “open” doesn’t mean “easy”. Here’s what to expect month by month.

Early to Late June: Open, but expect snow and mud

This is when we hiked it, and “officially open” turned out to be a bit of an oversell. There was mud all over the place from the snowmelt working its way down the mountain, snow lingering in every shaded section, and water literally bubbling up out of the ground in spots from the higher-elevation runoff, and the Lac Bleu detour in particular still had significant snowpack.

July and August: Peak season, peak conditions

This is when most people hike the Grand Balcon Nord, because the trail is fully clear of snow, the wildflowers are out, and the cable car and train are running on full schedules. The flip side is crowds and reservation pressure on the Aiguille du Midi cable car, so just book your time slot well in advance, especially for weekends.

September: Shoulder season sweet spot

If you can swing it, September is arguably the best time to hike this trail. The crowds thin out noticeably after the first week, the weather is often still settled, and the lighting takes on that golden alpine quality that photographs beautifully. Cable car and train hours start reducing toward the end of the month, so check current schedules before you plan.

October: Larches and last calls

By October, the larches across the valley turn golden, and the Chamonix landscape takes on a completely different character. The trail is technically still hikeable in early October if conditions cooperate, but lift and train hours drop significantly, snow can return at any point, and you’re playing a weather lottery. Check conditions carefully and have a backup plan.

Facilities on the Grand Balcon Nord

Facilities on this trail are clustered at the two ends, with absolutely nothing in between. So plan to carry enough water and snacks to get you from one end to the other, and don’t count on filling up your water bottle mid-hike. (And no, you definitely don’t want to drink from the streams, no matter how pristine they look.)

At Plan de l’Aiguille, the cable car station has a buvette/café, and toilets. We popped in and ended up buying a magnet rather than food, but it’s a solid spot to top off your water bottle and use the bathroom before you set off.

At Montenvers, you’ve got two options: a cafeteria with takeaway food (sandwiches, snacks, drinks) and a sit-down rifugio. Heads up that the rifugio is very expensive, even by Chamonix-at-altitude standards. Most hikers grab something quick from the cafeteria or save the celebratory meal for back in town. There are also toilets at the station, which you’ll likely appreciate after a few hours on the trail.

Accessibility and Trail Difficulty

The Grand Balcon Nord is rated as moderate, but those who are actually hiking it often share a more nuanced story than the rating alone. This trail throws a few terrain challenges like wet and mushy muddy sections (especially in early season), actual stream crossings where you’re hopping rock to rock, and the boulder field near Signal Forbes, where the footing is rocky and trippy enough that I’d think twice if knees or balance are of concern to you. We passed several elderly hikers taking long breaks at Signal Forbes who were clearly struggling on that section.

Why We Hiked It Twice: A Note on Mountain Weather

I don’t really count our first attempt at the Grand Balcon Nord in the uphill direction, because we turned around 30 minutes in. The forecast that morning had said “chance of thunderstorms,” which was vague enough that I talked myself into being optimistic. The first clap of thunder hit about 30 minutes in, and we high-tailed it back to the train station and made it down to town just as the rain started. It downpoured the entire evening.

We came back the next day under clear skies and had one of our favorite hikes of the whole trip.

Should You Combine Aiguille du Midi, Mer de Glace, and the Grand Balcon Nord?

Looking at the map, it’s tempting to think you can knock out all three of Chamonix’s headliners in one day. The Mont Blanc Multipass technically makes it possible. Other guides will tell you it’s doable. I’m here to tell you the math doesn’t work, unless you enjoy speedrunning the highlights of Chamonix without giving yourself the time to enjoy it! We did these three activities across two days, and even though the first hike attempt was cut short by a thunderstorm, it was still a lot. Here’s where the time actually goes.

Factoring in the altitude

The Aiguille du Midi summit is at 3,842 m. That’s high enough to leave you genuinely wiped out, especially if you’re not acclimatized. I felt the altitude pretty hard at the summit and was sunburned and a bit dehydrated by the time we descended to Plan de l’Aiguille. I perked up once we dropped down to the Grand Balcon Nord Trailhead, but it took a second. Starting a 7 km traverse hike right after a high-altitude experience is more demanding than the trail stats suggest.

Queues on Queues

At the Aiguille du Midi summit, the line for the Step into the Void glass box has timed floor markers that go up to two hours, and this line gets really long.

Also, even if you were hoping to get an early start and do Mer de Glace and the uphill Grand Balcon Nord, there are more lines to deal with. At Mer de Glace, the gondola down to the ice cave doesn’t start running until 10 AM. The whole experience of train up, Glaciorium, gondola down, 170 steps to the ice cave, cave visit, 170 steps back up, gondola up, train down, took us about two hours, so it would have been insane to also try to visit Aiguille du Midi in the same day.

My Recommendation

Pair the Grand Balcon Nord with one of the other two, not both. The cable car summit + the hike is a natural pairing because you’re already at Plan de l’Aiguille to start hiking. The Montenvers train + Mer de Glace + the hike is also doable, but you’ll start the hike late (because of the gondola hours), and have to hike in the uphill direction.

If you want all three, give them two days. You’ll enjoy each one infinitely more, and Chamonix has plenty of other ways to fill the time between.

What to Pack for the Grand Balcon Nord

This is a moderate alpine day hike, so you don’t need anything wildly technical — but a few things are non-negotiable in this terrain, and the mountain weather can flip fast enough that “I’ll be fine” is rarely the right call.

Quick disclaimer on my packing philosophy: I’m a runner, so I hike light. I wear my Salomon ADV Skin vest with maybe a liter of water, snacks, and a rain shell, and I let my Travel Buddy carry literally everything else. He’s a real one. If you’re hiking with someone who hasn’t agreed to this arrangement, here’s what should be in someone’s pack between the two of you.

For Your Feet

Trail runners with a good grip handle the Grand Balcon Nord trail well. I personally hike in Altras or Brooks and almost never wear heavy boots, even in the Alps. The exception is early-season conditions like ours, where waterproof boots might keep you happier through the mud and snowmelt. Trekking poles are popular with European hikers, especially on the steep sections, but I usually skip them because I don’t need them at home in Hawaii, but a $20 set from Costco does the job if you want extra stability on the descents.

For your body

You’ll want to dress in layers. The temperature swings between sun-baked and cloud-cold can be dramatic, and a lightweight rain jacket is worth its weight even on clear days. My Mammut shell packs down to about the size of a large potato and has earned its spot in my pack on every alpine trip. Add a hat, sunglasses, and sunscreen, because alpine sun is no joke.

For Everything Else

My Travel Buddy’s Osprey Talon carries the rest: 1-2 liters of water (a hydration bladder is the easiest hands-free option), snacks, the camera, our phones with offline maps downloaded, and some euros in cash for the cafés and Buvette at either end. Card acceptance is iffy at altitude, so don’t rely on it.
