The walk around Lake Paladru

This route will allow you to discover Lake Paladru in all its glory. A long hike (nearly 22 km) but without any technical difficulty. Best suited to experienced walkers or for tackling over two days.

Choose your starting point; the lake circuit can be started from four villages: Charavines, Bilieu, Le Pin or Paladru.
This large “Blue Lake”, exceptional for the beauty of its surroundings and its crystal-clear waters, was shaped by the mighty Rhône Glacier during the Ice Age. Situated at an altitude of 500 metres, nestled amongst wooded and agricultural hills, it is the fifth-largest natural lake in France. Its shores were home to one of the first human communities in Isère, dating back to 2700 BC (the Neolithic village of Les Baigneurs). Several sites are designated as “protected natural areas”.

We only use the app, so we cannot comment on the paper description.
The route is very easy to follow.
The advantage is that you get to see the lake often.
The downside is that you have to take a lot of roads, fortunately secondary ones.

For me, it was a rather uninteresting hike, apart from a few views of the lake… More than half of the route was on tarmac…
