A nice activity on Koh Rong is to rent a kayak. Do some exercise when you’re party on the Island. You can easy kayak from Tiu beach (main beach) to Kaoh Toch the little island in front of the beach and after that go to Long Set Beach. Thats one if the beautiful beaches on Koh Rong.
Price to rent a kayak
To rent a kayak it costs $8 a day or $15 for a two person kayak. I think that is a good investment for nice experience and exercise in one.
Tip: bring a waterproof backpack or leave your electronic devices at home 🙂 When you use a Go Pro use your floating gear.
