Chamonix with Kids: Aiguille du Midi, Mer de Glace & Epic Hikes
From the dizzying heights of the Aiguille du Midi to the ancient ice of the Mer de Glace, Chamonix-Mont-Blanc delivers some of the most breathtaking mountain experiences in Europe — and yes, you can do it all with kids.
Perched beneath the highest peak in Western Europe, Chamonix-Mont-Blanc is one of those places that makes you feel genuinely small — in the best possible way. Glaciers tumble between granite spires, cable cars soar to impossible heights, and the air at 3,800 metres is so thin it catches your breath before the view does.
We spent a week exploring Chamonix and its surrounding valleys as a family of four during a summer road trip through the French Alps, and the experience exceeded every expectation. The children, aged 9 and 13 at the time, tackled high-altitude trails, stood on a glass floor suspended 1,000 metres above a glacier, and proved that mountain adventures aren't reserved for adults.

Take the Cable Car to the Aiguille du Midi (3,842m)
If there is one experience you don't want to miss in Chamonix, this is it. The Aiguille du Midi cable car whisks you from the valley floor at 1,035 metres to a summit terrace at 3,842 metres in just twenty minutes — one of the highest vertical ascents by cable car in the world.
The views from the top are almost impossible to process. On one side, the entire Mont-Blanc massif unfolds in a wall of snow and ice. On the other, the jagged granite needles of the Aiguilles de Chamonix pierce the sky like a row of broken teeth. Far below, the Vallée Blanche stretches toward Italy in a river of white.
Step into the Void
The highlight for most visitors — and the moment that had our youngest gripping the railing — is the Pas dans le Vide, a glass-floored cage that juts out from the edge of the terrace with nothing but 1,000 metres of empty air beneath your feet. The Mont-Blanc summit fills the background, and on a clear morning, you can see all the way to the Matterhorn.
We arrived early, catching the first cable car at around 8 am, and the light at that hour was extraordinary — soft gold on the snow, deep blue sky, minimal crowds. If you're planning a visit, this early timing makes a real difference.
Watch the Panoramic Mont-Blanc Cable Cars
From the summit platform, you can watch the small red gondolas of the Panoramic Mont-Blanc line departing toward Pointe Helbronner on the Italian side. They glide silently above the Glacier du Géant, looking impossibly tiny against the scale of the mountains. Even if you don't take the crossing yourself, watching them from the observation deck is mesmerizing.
Look Up at the Summit Spire
Before heading back down, take a moment to look up at the Aiguille du Midi's own summit — the antenna-topped rock spire that gives the station its name. From below, it's an almost surreal sight: a man-made structure perched on a razor-thin granite needle at nearly 4,000 metres. The wispy cirrus clouds that drift around it only add to the drama.
Hike Down from Plan de l'Aiguille
Rather than taking the cable car all the way back down, we got off at the intermediate station — Plan de l'Aiguille at around 2,300 metres — and hiked back to Chamonix. The trail takes roughly two and a half hours, winding through alpine meadows with the Mont-Blanc massif as a constant companion.
The path is well-marked and not technically difficult, though there are some steep descents that require sturdy shoes. The reward is a continuously changing perspective on the glaciers and peaks above, plus the satisfaction of having earned your descent the hard way.
The children handled the descent well, though the 9-year-old was understandably tired by the bottom. Packing plenty of water and snacks is essential — there are no refuges or water points on the lower section of the trail.
Visit the Mer de Glace and Ice Cave
The Mer de Glace is France's largest glacier, a seven-kilometre river of ice that has been flowing down from the flanks of the Grandes Jorasses for millennia. You reach it via the charming Montenvers rack railway from Chamonix, a heritage train that climbs through pine forests to a terrace overlooking the glacier.
The glacier itself is both stunning and sobering. The grey-white ice, streaked with moraine debris, fills the valley below, and markers along the path show where the ice level stood in past decades — a vivid reminder of how much it has retreated.
From the viewing platform, a series of metal staircases — updated regularly as the glacier retreats — leads down to the Grotte de Glace, an ice cave carved fresh into the glacier each summer. Inside, the walls glow with an ethereal blue light, and sculpted ice figures add a touch of whimsy to the frozen corridors.
Conquer Le Brévent for the Best Mont-Blanc Panorama
If the Aiguille du Midi puts you on the same level as Mont-Blanc, Le Brévent gives you the perfect seat to admire it from across the valley. At 2,525 metres, the Brévent summit offers what many consider the finest frontal view of the entire Mont-Blanc massif — and we'd have to agree.
The cable car from Chamonix's Planpraz station takes you most of the way, and a short final gondola reaches the summit. From there, a sweeping panorama opens up: the entire north face of Mont-Blanc, the Bossons Glacier cascading toward the valley, the Aiguille du Midi's spire directly across, and the town of Chamonix miniaturized two and a half kilometres below.
We spent a morning here, hiking along the ridge trails toward Lac du Brévent before descending on foot to an intermediate station. The trails at this altitude are exposed but well-maintained, and the views are unrelenting in the best possible way.
Silhouettes on the Ridge
One of the most memorable moments of the trip happened on the descent from Le Brévent area — two silhouettes stood on a rocky outcrop against the bright sky, with the Mont-Blanc massif as a dramatic backdrop. The combination of scale and light created a scene that felt almost staged, but was simply the magic of being in the right place at the right time.
Explore Chamonix Town
After several days of high-altitude adventures, Chamonix town itself deserves some time. The pedestrianized centre is lively but not overwhelming, with outdoor gear shops, mountain-themed restaurants, and a genuine alpine atmosphere that feels earned rather than manufactured.
Strolling through the streets with the Aiguille des Drus and Aiguille Verte visible at the end of nearly every avenue is a constant reminder of where you are. The town makes an excellent base, with everything you need within walking distance.
One highlight we stumbled upon was a rafting group navigating the Arve river right through the centre of town — the milky turquoise water churning around their blue raft while wooden chalets lined the banks. It's a brilliant activity option if your family is looking for a break from hiking.
The Chapel at Les Praz-de-Chamonix
A short walk from the centre brings you to Les Praz-de-Chamonix, where a small stone church with a wooden bell tower sits on a green lawn. Behind it, the Aiguille des Drus rises dramatically — one of the most photographed scenes in the Chamonix valley. It's the kind of quiet spot that balances perfectly against the high-adrenaline experiences above.
Fly High: First Paragliding Experience
One of the highlights of this Alps trip was a first paragliding tandem flight above the Chamonix valley. Taking off from altitude near the Aiguille du Midi area and soaring above the glaciers and granite spires with Mont-Blanc filling the horizon is a genuinely transformative experience.
If you've never tried paragliding, Chamonix is arguably the most spectacular place in the world to do it. Several operators offer tandem flights of varying lengths, and you don't need any experience — the pilot handles everything while you take in views that no cable car or hiking trail can match.

Practical Information
How to Get There
Chamonix-Mont-Blanc is in the Haute-Savoie department of eastern France, about 80 km from Geneva, Switzerland. The easiest approach is to fly into Geneva Airport (GVA) and drive — it takes roughly one hour and fifteen minutes via the A40 motorway. The road is straightforward and well-signposted. You can book a rental car online to arrange transport in advance.
Alternatively, the Mont-Blanc Express train connects Chamonix to Saint-Gervais-les-Bains, which is on the main TGV network from Paris (about five and a half hours total). During summer, direct bus services also run from Geneva airport. Compare flight options to Geneva from your home city.
Best Time to Visit
Summer (June to September) is ideal for hiking and cable car access. July and August bring the warmest weather and longest days, but also the biggest crowds — booking the Aiguille du Midi cable car online in advance is strongly recommended during peak season. We visited in August and enjoyed consistently clear skies, though early morning starts were essential to beat the heat at lower altitudes.
Budget
The Aiguille du Midi cable car costs around €70 for adults and €60 for children (2024 prices). A combined pass covering the Aiguille du Midi, Montenvers (Mer de Glace), and Le Brévent offers better value if you plan to do all three. Accommodation in Chamonix ranges from budget gîtes at around €80/night to upscale mountain hotels at €250+. Restaurant meals average €15-25 per person for a main course.
Tips for Families
Altitude can affect young children — at 3,842 metres, some kids (and adults) may feel lightheaded. Take it slow, drink plenty of water, and don't plan a long hike immediately after the Aiguille du Midi. The Mer de Glace ice cave involves quite a few stairs, which can be tiring for small legs. Bring layers — even in August, the summit of the Aiguille du Midi hovers around 0°C.
