I hired the only hardtail bike available in Cilaos, a Scott Aspect 50. There’s a forest bike park just outside the town with a selection of graded trails. Unfortunately the road tyres and brakes really won’t do that - I turned back after 10 m. down one of the red trails. So just the loop up to 1500 m. altitude on the forest road, but good enough to ride through cloud forest of Cryptomeria trees with the track lined with Ginger plants.
Cilaos (1150 m.) also has a mini BMX pump track, hidden and away from tourists. The locals made space for my efforts, then showed me much more. Anyhow great to feel the Gs of a different track to Keswick and Marseille and the bike was fine for that.
