Hiking

The trek to the top of Le Pouce is considered an easy hike. However, the ascent is very steep, especially near the thumb. Le Pouce can be reached from Moka or Port Louis. Unlike Pieter Both, climbing gear is not needed. From the peak, Port Louis, Moka, and Beau-Bassin Rose-Hill can be seen, as well as many other places around the island.


History

Le Pouce was formed ten million years ago in a basalt lava dome. Charles Darwin ascended the mountain during his voyage around the world. He recorded in his journal: As time went by and tourism increased, hiking Le Pouce became a tourist attraction.


Le Pouce Nature Reserve

Le Pouce Nature Reserve was created in 1951. It protects an area of 0.69 km2 on the mountain's northwest flank.UNEP-WCMC (2021). Protected Area Profile for Le Pouce Nature reserve from the World Database of Protected Areas. Accessed 18 August 2021
