The hike was about 2.5 km with 340m of elevation difference between parking...
It was sad that only few people knew and been to this place like me and some of my friends, It is a gift from god to the people to enjoy this very beautiful place, first, if you are coming from Port au prince, it will took you 2 hours of drive to get to Petit Goave, almost 3 hours...
