The lake of Paladru is a beautiful lake located in Isere at 80 km from Lyon and 50 km from Grenoble.
The lake is very popular in summer because its crystal clear water is perfect for swimming. There is no real hiking path around the lake, it is rather sidewalks built along the road. There is nevertheless a hiking circuit around the lake but it is very long (22 km).
If you are in the area, you can make a small detour to admire the lake of Paladru.
