The lake of Sainte Marguerite is a pretty mountain lake at 2227m located on the resort of Les Orres (Hautes-Alpes).
This is the great hike to do from Les Orres. It is very easy to access, it is not possible to get lost because it is very well marked. It is suitable for all ages (although you still have to walk for 4 hours). There is a large parking lot at the starting point of the hike.
