There are a variety of trails at different levels in this area. At les Grassonnet they tend to be flat. At Argentière the trails go through the forest where there are some steeper sections.
Located in Les Iles between Chamonix and Argentiere. Driving from Chamonix through the "para-avalanche" tunnel, 100m after the Indoor Tennis courts on the left side of the road. It is not so easily seen driving from Argentiere. Slow down after the bus stop in Les Grassonets as it is the next building on the right.
