Mont Boron, Mountain summit in Nice, France.

Mont Boron is a hill in southeastern Nice rising to 191.3 meters, its slopes covered by a 57-hectare forest and built up with tiered houses and villas above the sea. The summit area is wooded, and the hill extends northward into Mont Alban. A 400-meter-long battery built in 1886–1887 occupies part of the site.

Mont Boron was a strategic site from antiquity. Its summit battery, a 400-metre-long enclosure covering 15,000 m², was built in 1886-1887 to protect both the Baie des Anges and the roadstead of Villefranche-sur-Mer. The separate Fort du Mont-Alban, just north, was built between 1557 and 1560 under Emmanuel-Philibert of Savoy against Turkish and French invasions. The site remained military until the 19th century.

The forested park serves as a cherished outdoor space where locals and visitors walk among pine and cork oak trees typical of the Mediterranean region. People come here to escape the city and enjoy nature without traveling far from Nice.

The hill is easily accessible by bus from the city center, with trails suitable for different fitness levels. Wear proper footwear as paths cross woodland and rocky sections.

Beneath the hill lies the Lazaret Cave, where archaeologists found stone tools and other remains from the Middle Paleolithic period. These artifacts show that people inhabited this area thousands of years before the fort was built.
