The Mont Boron Forest Loop is a roughly 5 km circuit through the Parc forestier du Mont Boron, the pine-covered hill east of Port Lympia in Nice, on the French Riviera. The Nice Cote d'Azur tourist office gives a duration of about 1 hour 50 minutes. Access is by public transport: Tram T2 runs to the Port stop at Port Lympia, and from there it is about a 10-minute walk up Boulevard Carnot to the first forest gate, near the address given as Boulevard Carnot and Route du Fort du Mont Alban. No permit or entry fee applies. The summit of Mont Boron sits at roughly 190 m, and the forest roads climb about 160 m from the port, which keeps the route within easy range for most walkers. The surface is a mix of asphalt forest roads, compacted earth and gravel paths, with some stone steps; trail shoes or sturdy trainers are sufficient. Tree cover is generous because Aleppo pine and holm oak shade much of the loop, though viewpoints on the ridge are exposed to wind and sun. Landmarks include the shaded forest roads on the lower slopes, lookout points over the Baie des Anges and Villefranche bay, and the Fort du Mont Alban on the crest, a 16th-century fortification that gives the route a natural turn-around point for walkers who want a shorter outing. Because the hill is a fire-prone Mediterranean forest, access can be closed on days of high wildfire risk in July-August, so checking conditions in advance is advisable. Walkers should carry their own water, since fountains are few and no refuge huts exist; the city is close enough that bailing out downhill toward Port Lympia or Boulevard Carnot is always possible. A phone with an offline map helps at the several path junctions, where signage can be sparse. The hill is popular with local joggers and dog walkers, so weekday mornings are quietest. A light jacket is useful for the ridge, where breezes from the sea keep temperatures lower than in the city below.
