On my very first day on the island, I got a small tour of a few places and I happened to see some guys canyoning. I made it my assignment to get to do this since I missed the opportunity for it in Guadeloupe Island.
A new activity that I actually did was camping at the L’Hermitage beach. It was a fun night, warm, no mosquitoes. You actually don’t even need a permit, just come and pitch your tent or hammock in the evening and sleep away as you listen to the waves. It’s also very safe so no need to worry.
