One of the activities you could do on Koh Chang is to visit a waterfall. Khlong Nonsi Waterfall is a great option because it’s free of charge and one of the less popular ones on the island. It’s situated on the east of the island and makes for a fun outing.
To get there you would need to go pass the ferry harbors on Rural Road if you’re coming from White Sand Beach. On the right side of the road,lookout for a large open field where the Koh Chang District offices are. There will be a sign directing you to the waterfall. Follow the road for about 1 km and you’ll come out to a dead end. To your left you’ll see some signs about the waterfall. Follow the hidden path for a few steps to get to the waterfall.
There aren’t any shops neither people selling food & drinks, so it’s best you go prepared if you plan to stay for a while. You will enjoy the privacy and being surrounded by nature.
