Last Monday, I went to Piton de la Petite Riviere Noire with my colleagues. At 828m, it’s the tallest mountain of the island but it might be infact one of the easiest ones to climb.
Just go to the Black River National Park, park ur car/van/… in the parking next to the viewpoint (5 on the map), walk about 500m down the road and u’ll see the track indicated by Black River Peak (yes they did not put Piton de la Petite Riviere Noire!).
As soon as you go down the track, it’s a bit confusing – instead of going up, you go down. It’s only after about 30 mins walk that you reallys start the ascent which is basically a gentle rise to the top. After a little scrambling for about 10 metres, you reach the summit and enjoy the view.
The round trip is about 9km and roughly a 3-4 hour trip.
