Our tour in Khao Sok National Park
We stayed at "Good View" in Khao Sok. A lovely friendly Thai family own it and treat you as friends. The units are very new and clean up high on stilts with a sky bridge. A beautiful balcony on the back overlooking a mountain and jungle with the most comfortable chairs I've had in Thailand.
I would recommend to do the trek in the national park by the river, also have a guide take you canoeing Down the river. The dam is an hour drive away and is amazing. We count Khao Sok as our best experience in Thailand.
