Koh Sichang

Small lovely island, Koh Sichang is off Si Racha 120 km southeast from Bangkok and 20 km north from Pattaya. Stony, surrounded by a turquoise sea, Ko Sichang offers splendid landscapes and small lovely beaches uncrowded on weekday.

This is also an interesting place to visit with its temples perched on hills offering a beautiful view of the port and its former royal palace where Vimanmek Palace which was deconstructed and reconstructed in Bangkok was built. You can still see the design of foundations on the ground. 
Ko Sichang is very small, you quickly go around it by motorbike, but it is interesting to spend at least one night on the island. The atmosphere is much more authentic than on the other islands in the area.
