Here’s a quick Guide to Koh Samui’s tropical coasts.
The West coast: The Island’s main town of Nathon on the upper west coast offers little in the way of sightseeing, but has a reasonable selection of shops and restaurants. There are a number of small beaches here, but they do not compare with those on the east coast.
The North coast: Consisting of a series of smaller beaches, some of which are good for swimming, snorkeling, and windsurfing when the northeast breezes blow from December to February. Hat Phra Yai at Bangrak is best known as the Big Buddha Beach named after the tall gold tiled sitting Buddha on a small island connected to the beach by a causeway.
The North East coast: This coast provides a series of smaller capes and picturesque coves, some difficult to reach by road. From here there are excellent views over to Ko Pha Ngan.
The East coast: Samui’s longest and most beautiful beach of Chaweng is located here. Fringed with swaying picture postcard palms, it extends for 5km and makes for wonderful walks, particularly at dawn or sunset. Chaweng also has the largest variety of water sports, and a good selection of shops and entertainment. The Amari Koh Samui is ideally located on the quiet northern end of Chaweng Beach.
The South East coast: Samui’s second longest beach of Lamai is here, again with good tourism infrastructure, but with less sand and generally lacking the tropical beauty and exotic feel of Chaweng.
