The iconic trails you can’t miss
Lac Blanc – a mirror of the sky
The Lac Blanc hike is often the first name that pops up when you search for Day Hikes in Chamonix. Starting at the Teleferique du Bossons, the trail climbs through alpine meadows, skirts the Plan de l’Aiguille and rewards you with a crystal‑clear lake that reflects Mont Blanc’s crown. At roughly 4.5 km each way, the ascent is moderate, but the final push past the rocky ridge demands a steady rhythm. On a clear day the water turns a shocking shade of blue, echoing the nearby Lac Bleu and Lac Vert. Bring a lightweight jacket – mountain weather changes faster than a tram timetable.
Grand Balcon Sud & Grand Balcon Nord – ridgelines with a view
Two classic routes diverge from the Teleferique de la Flegere. The Grand Balcon Sud sweeps eastward, hugging the edge of the valley and offering uninterrupted sightlines toward the Mont Blanc massif. Midway, you’ll encounter the historic Le Tour bivouac, a perfect spot for a snack. The northern counterpart, Grand Balcon Nord, winds past the Glacier des Bossons and provides a dramatic perspective of the La Jonction viewpoint, where the glacier splits like a frozen river.
Aiguille du Midi and Plan de l’Aiguille loop
For those who crave altitude without technical climbing, the Aiguille du Midi cable car drops you at 3 850 m. From the summit platform, a marked path leads down to the Plan de l’Aiguille, then rises again to the Signal Forbes ridge. The loop can be completed in 5–6 hours, and the wind‑whipped scenery feels otherworldly. Early summer sees wildflowers clinging to the scree, while October brings a pristine frost that turns the horizon into a silver tableau.
Alpages du Blaitière and the Cascade du Dard
Head north from the Teleferique du Bossons toward the Alpages du Blaitière. The meadow‑filled approach is gentle, making it suitable for families. Past the alpages, a short detour leads to the Cascade du Dard, a hidden waterfall that tumbles over basaltic rocks into a pool perfect for a quick dip. The entire round‑trip stays under three hours, yet the payoff of alpine flora and the roar of the cascade feels like a secret only locals know.
Lake journeys: Lac du Brevent, Lacs des Cheserys, and Les Sources de l’Averyon
These lake‑centric hikes can be strung together for a longer day. Start with the lift to Lac du Brevent, a high‑altitude basin framed by rocky outcrops. From there, a ridge walk brings you to the Lacs des Cheserys, a trio of serene waters that mirror the sky in perfect symmetry. A final descent leads to Les Sources de l’Averyon, where crystal springs emerge near the foot of the Montenvers station. The route works well in summer when the streams are swollen, and in early autumn when the surrounding larch turn golden.
| Trail | Distance (round‑trip) | Estimated time |
|---|---|---|
| Lac Blanc | 9 km | 5–6 h |
| Grand Balcon Sud | 12 km | 6–7 h |
| Aiguille du Midi loop | 7 km | 5–6 h |
| Alpages du Blaitière & Cascade du Dard | 6 km | 2–3 h |
| Lac du Brevent circuit | 10 km | 5–6 h |
Getting there: transport & access
The Chamonix valley is exceptionally well‑served by public transport, making it possible to leave the car behind. The bus network operates hourly from the town centre to most lift stations – for instance, the Teleferique du Bossons can be reached in 15 minutes on line 2, while the Teleferique de la Flegere is a 20‑minute ride on line 5. If you prefer the flexibility of a car, the cable car terminals provide ample parking, though spaces fill up quickly during peak season.
For hikers staying in Les Houches, the “Grand Balcon” train service runs directly to the Le Tour stop, where you can start the Grand Balcon Sud trek without climbing the valley floor. Meanwhile, the Montenvers Railway – a historic rack railway – carries you up to the famous Mer de Glace glacier. The short walk from the station leads to the Glacier des Bossons viewpoint and the La Jonction lookout, both perfect for a quick photo break.
Tip: Purchase a “Chamonix Transport Pass” (available at any tourist office). It grants unlimited rides on buses, trains and lifts for a day, saving you both time and money.
Practical tips & what to pack
Essential gear
- Sturdy waterproof hiking boots with good ankle support.
- Layered clothing: moisture‑wicking base, insulated mid‑layer, wind‑proof jacket.
- Sun protection – even on cloudy days the altitude amplifies UV.
- Map (paper or offline digital) and a compass; some trails have limited cell coverage.
- Enough water – aim for at least 2 L per person, plus snacks high in carbs.
Safety considerations
Mountain weather can shift without warning. Always check the forecast on the Météo France Alpine portal before setting out. If you hear a sudden rumble, it could be the distant movement of the Glacier des Bossons – stay on marked paths. In October, be prepared for early snow on higher sections like the Signal Forbes** ridge; crampons or micro‑spikes become useful.
Eco‑friendly etiquette
Chamonix is a cherished natural asset. Stick to existing trails, carry out all litter, and keep noise to a minimum around grazing livestock in the alpages. The valley’s Alpages du Blaitière host seasonal cows; a gentle “bonjour” is always appreciated but never feed the animals.
Seasonal considerations & best time to hike
While the valley enjoys a long summer, each month offers a distinct character. June and July bring vibrant wildflowers, especially around the Lac Blanc cirque. August can be busy, but the longer daylight hours offset the crowds. September is ideal for photographers – the larch forest turns a buttery gold, and the light is often soft and golden. October, though cooler, offers a serene, almost desert‑like experience with the first frosts glinting on the Grand Balcon Nord ridge. Winter hikes are possible but require specialist equipment and local guides.
Frequent Asked Questions
Can I do a day hike without using the cable car?
Yes. Many trails start from the valley floor and can be reached by bus or on foot. The Alpages du Blaitière loop is a popular option for those who prefer to walk the entire distance, and the Les Sources de l’Averyon hike is accessible via a short bus ride followed by a gentle ascent.
What is the safest time of day to start a hike?
Starting early – around 8 am – is generally advisable. Morning conditions are usually more stable, and you’ll avoid the peak of alpine sunshine, which can cause rapid snow melt and increased avalanche risk on higher passes.
Are dogs allowed on the trails?
Dogs are permitted on most marked paths, but they must be kept on a leash near livestock or protected areas such as the Glacier des Bossons. Always bring waste bags and respect local signage.
How long does it take to hike from the town centre to the Mer de Glace?
The Montenvers Railway departs every 30 minutes from Chamonix town centre and takes about 20 minutes to the Mer de Glace station. From there, a short walk (10‑15 minutes) leads to the glacier viewpoint, making it feasible for a half‑day outing.
Do I need a special permit for high‑altitude hikes?
No formal permit is required for the day hikes listed above. However, if you plan to venture onto off‑track terrain or glacier routes beyond the marked paths, you must register with the local mountain rescue (Samu 05) and consider hiring a certified mountain guide.
Putting it all together: your perfect Chamonix day out
Choosing a route depends on your fitness level, time constraints and the weather on the day of travel. A balanced itinerary could look like this: take the bus to the Teleferique du Bossons, ascend to the start of the Lac Blanc trail, enjoy a midday lunch by the sparkling lake, then descend via the Grand Balcon Sud to the Le Tour bivouac for a coffee before catching a return bus to town. This loop offers variety – alpine lake, ridge walk, and a charming mountain hut – all within a single, rewarding day.
Remember, the mountains reward preparation and respect. Check lift schedules, pack layers, and stay aware of the ever‑changing alpine climate. With these tools in hand, the valleys and peaks of Chamonix are yours to explore, one unforgettable day hike at a time.
