Grimentz is located in the Valais region of Switzerland, not too far from Verbier. The valley holds several small resorts, all covered by the same pass. The separate nature of the resorts gives plenty of easy-access backcountry runs between resorts, with easy tours or valley buses back to base.
Grimentz itself has rad freeride terrain, both in and out of bounds. The lifts go from well below the treeline all the way to 3000m and give access to most aspects so it's almost always possible to find good snow, especially as it's very quiet and rarely tracked-out.
The resort village is really authentic, with the original old town still preserved and in-use. By Swiss standards, it's also pretty affordable.
