The Queyras Regional Natural Park (dead link: January 2023) is in the Hautes-Alpes part of France.
This is one of the smallest regional natural parks in France, south of Briançon and reaching the Italian frontier. It's hard to see, however, how any other park could beat it on sheer beauty, even though its principal peaks are 300 m lower than the giants of Haute Savoie
The area has only been publicly accessible for a short time and is relatively unspoiled.
The mountains, though low by Alpine standards, lack nothing in shapeliness.
The area is remarkably rich in most of the flora associated with Alpine areas. Marmots abound.
There is an extremely friendly micro-climate with a lot of sunny days in a year. However campers in June need to expect extreme cold at night. Because of the variation between this and the heat of the afternoon, streams can become rivers during the day and flowers can be seen growing newly where snow has only recently melted.
Access by road only from Briançon in the north and Giullestre to the west.
As many walks as you can manage. Count the sundials in any Queyras village. They are a speciality of the region.
Be very wary of rising water levels from melting snow.
