Koh Samui Land Overview

Koh Samui, being a large island, offers a wide variety of land options. The main areas of interest, which contain most of the population, are spread out and distinct in nature.

Nathon: The Administrative Hub

On the west coast lies Nathon, the main town and administrative center of Koh Samui. Nathon is the primary port for ferries to the mainland and hosts all major regional and government establishments, including immigration offices and the main police station. Despite its administrative importance, Nathon remains relatively quiet and less commercialized compared to the island’s more tourist-centric areas. The presence of nearby facilities, such as a Tesco, and virgin land overlooking Angthong Marine Park, makes Nathon an attractive area for those seeking more secluded locations.

Cheweng: The Tourist Hotspot

Cheweng, located on the east coast, is the island’s main tourist area, known for its vibrant nightlife and bustling atmosphere. It is virtually opposite Nathon and offers a stark contrast with its lively environment. Cheweng boasts some of the finest beaches on the island, making it a magnet for tourists and investors alike.

Lamai: The Second-Busiest Resort Area

South of Cheweng is Lamai, another busy resort area. Lamai offers a more relaxed atmosphere compared to Cheweng but still provides a wide range of amenities, including restaurants, bars, and shops. The beach in Lamai is also a major draw, with its clear waters and soft sands.

Choeng Mon: Secluded Yet Accessible

North of Cheweng lies Choeng Mon, a quieter beach bay area. Choeng Mon combines relative seclusion with easy access to nightlife and busier locations, making it a popular choice for those seeking a balanced lifestyle. It offers a serene environment with fewer tourists, ideal for those looking for a peaceful retreat.

Northern Beaches and Smaller Towns

The northern part of the island features great beach areas and smaller towns such as Maenam. Maenam offers beautiful beaches but fewer amenities and restaurants compared to other areas. It is ideal for those looking for a quieter and more laid-back environment.

Southern and Inland Areas

The southern part of Koh Samui is characterized by quieter, unspoiled areas between Lamai and Nathon. Inland areas are mountainous and largely untouched, offering a different kind of natural beauty. These areas are perfect for those seeking a more rural and serene setting away from the bustling tourist spots.
