Eastern Thailand is half mountain, half ocean. Although there aren’t many provinces here, it still has a lot of amazing sights and stunning locations to visit just like the rest of Thailand such as Koh Samed, Koh Chang, Koh Mak, Koh Lan, Koh Si Chang, Bang Saen Beach, Pattaya, Jomtien Beach, Laem Mae Phim Beach, and Mae Ram Phueng Beach.
