The highlight of my excursion was the hike in the park. The view from the top is breathtaking. Carry closed shoes as the path to the peak is very rugged. They have placed a clock at the peak. A person sits at the second viewpoint...More

recommended companies: Grand sea (offers tour by speed boat) and Samui Island tour (offers slow boat). I went by both companies.. but prefer Samui Island tour with their slow boat.. The tour organization was just perfect
