Hey Medusa, Can you share your experience with our guys? From my view, There is no more interesting places in sinharaja forest. We just enjoyed ourselves with our friends gang. We saw some species of trees and also some reptiles. Otherwise, Sinharaja forest bathing place is the best place to enjoy there. There are lot of leeches in sinharaja forest. Really, We were irritated by those leeches. So, Don't forget to bring salt with you guys. That is the best preventing method from those leeches. This is not a wow place to enjoy. Just you vcan visit the largest rainforest in Sri Lanka and also you can add this place in your travel diary.
Advice: If you want to visit all places then arrange a trip advisor in the front of the forest entrance. That may help you for the best trip.
