After taking the Train des Merveilles from Nice-Ville station through the Paillon and Roya-Bévéra Valleys up to the medieval charm of Tende, where you'll stop for lunch, you'll hop back on the train and head across the border to the Italian border town of Limone. Here is where the hiking begins! It's a 6km trail leading you up through the tiny settlement of Tetti Meci to the charming village of Limonetto, where you can lodge in the Rifugio Alpeselle.
