About Tour du Grand Roc
Tour du Grand Roc is a 16.7 km hiking route in Auvergne-Rhône-Alpes, France. It climbs roughly 367 m (1,204 ft) along the way. Most people take around 4 hr 5 min at a comfortable pace, plus stops. Treat it as a full day out: the ascent is relentless in places and there are few easy escape points.
The coastline does the heavy lifting: cliff edges, coves and open horizon for most of the way.
The circuit closes on itself, which makes logistics simple: one car park, one round of 10.4 mi. It is not consistently waymarked, so carry a map or a downloaded track rather than relying on signs.
It walks well across three seasons, with spring and autumn offering the best combination of light, temperature and quiet paths. The nearest town of any size is Aix-les-Bains, about 28.6 km away, which is where most people base themselves. The route is maintained by Pays d'Albertville.
In short, Tour du Grand Roc suits fit hikers with a habit of long days and an eye on the forecast. Dog access is not formally recorded here, so check locally before bringing one.

The route in detail
The loop is usually walked clockwise from the main trailhead. The first third does most of the climbing, so settle into a slow rhythm early rather than trying to hold a flat-ground pace. The return leg is the reverse of the outward journey, which makes it easy to judge remaining time.

Tips from the trail
- Early morning and late afternoon give the best light and the quietest paths.
- Aim for april to october for the most reliable conditions.
- Check the tide table if any part of the route runs along the beach.
- Download the track to your phone before you leave. Signal is not guaranteed.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- This route is long and sustained. Turn back early rather than late if the weather closes in.
- Cliff edges may be unfenced and undercut. Keep well back from the drop, especially in wind.
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in France are reached on 112. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage is generally usable along this route, but do not rely on it as your only plan. If the weather deteriorates, descending the way you came is almost always the safer option.
What to bring
- Comfortable, broken-in hiking shoes or boots
- Weatherproof jacket
- At least 1.5 litres of water
- Offline map and compass
- Head torch and spare battery
- Extra warm layer
- Sun hat, sunglasses and high-factor sun cream
- Small first aid kit including blister plasters
Photography
Golden hour along the cliffs is the obvious call, and a slow shutter on the water at the base of the rocks adds movement. Because it is a loop, the light changes direction as you go, so save some memory for the back half. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
