Les Pontons Suspendus is one of the best locations to snorkel Lake Annecy and discover its aquatic life. Located near the city center and easily accessible, don’t hesitate to check it out if you’re staying in the area. Around the pontoons and all along the shore, you will spot aquatic plants, several species of freshwater fish (perch, tench, roach, blenny) and crayfish.

How to get to the Les Pontons Suspendus snorkeling spot in Annecy

Water entrance for snorkeling Les Pontons Suspendus

You can enter the water either from the pontoons that line the shore at this part of the lake (and which gave the site their name), or from the rocks.

Les Pontons Suspendus snorkeling exploration tips

Les Pontons Suspendus site can be divided into two snorkel areas:

1. On the right (north of the car park), the shore is bordered by a water promenade, laid out at 3-4m from the edge.

Underwater, the shore extends into a steep drop off. In places, you’ll find fields of aquatic plants (Myriophyllum sp.), in which fry and juveniles of several species of fish hide.

By skindiving 1 or 2m deep on the drop off, you may spot schools of roaches and perch. Sometimes, a big trench has been dug through the mud. The area located under the pontoons (↕2-4ft/0.5-1.5m) are also very lively, with many perch sheltering around the stilts.

2. On the left (south of the car park), the shore returns to its “natural” state. You can snorkel along it until the tall trees.

Here, the drop-off begins more than 10m from the shore, leaving a nice shallow area (↕2-6ft/0.5-2m) to explore along it. On the rocky bottoms, look for freshwater blennies and signal crayfish, which remain close to their hiding places. Perch and roach are easy to see in the shallows.
