The view from the large building under construction also promises to be interesting but it should not be finished before many months. If you are hungry at the bottom of the car park, after the pink Ganesha statue, there is a nice small local restaurant.
The museum entrance costs 20 THB also
The road to Wat Teepangkorn is not easy, do not venture there by scooter if you are not a very skilled 2 wheels driver. This stop is on the program of some Koh Samui agencies that take you there in 4x4 cars.
