Hi!
Villefranche, L'Escarene (and other towns on the railway line to Sospel) are easy to get to but on the Chemin de Fer de Provence, the Train des Pignes, narrow gauge line skirting the Var valley, Entrevaux is a must.

There's not only a motor-cycle museum but the organ in the church was built in 1717 by Eustache . . .
