The Cascade de Clars via l'Ubac de Brainée and the Montagne des Louquiers

Superb hiking in the back-country of Grasse.
On the program, megaliths, magnificent viewing points over the entire coast (in clear weather) and to finish, a superb waterfall in an exceptional setting.
Gilette and the Estéron gorges

Gilette and La Clue.
From the village of Gillette, perched on a rocky outcrop, this walk takes you to the medieval bridge of La Cerise (scenes from the film "The Hunchback" were shot here in 1997) and then winds through the Estéron gorges.
Bréche du Mont-Saint-Martin via Sallagriffon

This circuit is ideal on sunny days and a surprising route thanks to the diversity and beauty of the valley, which is still wild. On the northern slope, you'll appreciate the quiet atmosphere of the pine forests and the oaks that dominate the verdant agricultural plain of Sallagriffon, with a panoramic view up to the foothills of the Mercantour mountain range. On the southern slope, you'll appreciate the magnificent mineral landscapes with tremendous views of deep clues carved out by the capricious course of the rivers.
Baoux des Blancs et des Noirs via the chemin du Riou
This walk begins with a stroll along the peaceful Chemin du Riou, a balcony overlooking the Pays Vençois, then climbs up to the two cliff promontories, taking in a wide panorama from Nice to Théoule, and perhaps even a glimpse of Corsica!
Le Castellaras and Lac de Thorenc from La Pinée

Another route providing access to the ruins of Castellaras and Lac de Thorenc follows part of the existing circuit on Visorando. It starts from the D5, at a place called La Pinée, and is just as interesting.
I have classified this route as difficult due to its orientation and length. It is advisable to bring a suitable tool for this route.
Saint-Vallier loop via Cabris and Saint-Cézaire
This is a large loop that goes around one of the first foothills of the Pré-Alpes d'Azur, following old paths and the Gorges de la Siagne. The loop is long but mostly flat, except for the descent to Cabris and the very steep climb back up to Saint-Vallier. The villages offer views and shops for refreshments. It is recommended to start early, as the second third of the hike will be sheltered from the southern sun, but the hardest part is exposed. There are few alternative routes or shortcuts once you are in the gorges between Saint-Cézaire and Saint-Vallier.
