About Lac du Lou

Lac du Lou is a 6.9 km hiking route in Auvergne-Rhône-Alpes, France. It climbs roughly 370 m (1,214 ft) along the way. Most people take around 1 hr 59 min at a comfortable pace, plus stops. It sits firmly in moderate territory: enough climbing to feel like a proper day out, never enough to become a slog.

The water is the anchor of the route, still enough on calm mornings to mirror everything above it.

The circuit closes on itself, which makes logistics simple: one car park, one round of 4.3 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.

In short, Lac du Lou suits regular walkers who want a full day without technical ground. 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.

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

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
Sun hat, sunglasses and high-factor sun cream
Small first aid kit including blister plasters

Photography

Overcast light suits this route better than harsh midday sun, especially under tree cover. 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.
