This easy-to-access circuit is perfect for exploring a loop that takes in varied and easy paths. However, bring a lamp as there are many tunnels and they are sometimes poorly lit.

Small, rocky stretch of beach that you can climb down to, as well as good views of Lac Le Grand Maclu.

Beautiful view of the lake, and afterward, we had a lovely swim in the lake. Nice bar with delicious ice cream.
