We are staying at St Dalmas about 8 km west of St Martin Vesubie. On our first day we hiked up Tete du Barn (2529 m) above Col du Barn. The access was excellent as we could drive to 2000 m on a paved road above St Dalmas.
There was lots to see a few hundred metres from the parking lot, particularly orchids. But the outstanding plant was a Maritimes Alps endemic Viola valderia growing from a tight mat of narrow leaves, unlike typical violas. The Viola lutea had huge yellow flowers some nearly white.
