Kaeng Krajarn is the most extensive national park of Thailand occupying an area of 2,915 square kilometers and it is still largely unexplored. The area is rich in flora and fauna and has an 18-tired waterfall named Namtok Tho Thip. After spending some time at the waterfall, we then take a 1-hour boat trip around the Kaeng Krachan Dam. After lunch at a local restaurant, transfer back to your hotel.
