Mont Passot, Volcanic summit in Nosy Be, Madagascar.

Mont Passot, known in Malagasy as Bongo Pisa, is a volcanic hill in the centre of Nosy Be. It reaches 326 metres, or 329 metres in Dutch sources, making it the island's second-highest point after Mont Lokobe. It lies in the west of the island, surrounded by several lakes including Amparihibe, Nosy Be's largest lake, and the neighbouring Antsidihy lake.

The peak was named after Pierre Passot, a French naval officer who brought Nosy Be under French control in 1841. This name reflects the colonial period that shaped the island's early modern history.

The summit is the venue for the final of Nosy Be Symphonies, a classical music festival of the Indian Ocean, held each year at the end of August. The hill is also known by its Malagasy name, Bongo Pisa.

The summit lies in the west of Nosy Be and is reached by road, with the final stretch on foot to the viewpoint. The surrounding lakes, including Amparihibe, the island's largest, and neighbouring Antsidihy, sit below the top. Heat builds through the day, so go early or late and carry water.

Mont Passot is also called Bongo Pisa in Malagasy. The summit stands in western Nosy Be, ringed by several lakes, among them Lake Amparihibe, the island's largest, and the neighbouring Lake Antsidihy. The Mitsio archipelago, Nosy Faly, Nosy Komba, Nosy Sakatia, Nosy Tanga, Nosy Ratsy and Nosy Tanikely can be made out from the top.
