Na Thon is situated on the west side of the island, which faces the mainland. The port serves as a centre for the tourism business, and harbours ferries from Ka-nom port; express ferries from Surat Thani; and ferries frequenting the route between Koh Samui and Koh Pha-Ngan. Boats offering tours to the Ang Thong archipelago also dock here, and ticket offices sell trips to Bangkok. This beach is therefore the main hub for travel to other locations.
Na Thon beach is also the site of government offices, shopping centres, food markets and souvenir shops.
The beach is suitable for walking, with local restaurants serving inexpensive fresh food for tourists to choose
from along the beach road. In the evening, the beach provides another place to watch Koh Samui is striking
sunsets.
Accommodation and Facilities
There are few places to stay in this area, as it is not a popular tourist destination, so the range of accommodation is less appealing than in other attractive tourist spots, such as Chaweng, Lamia or Bo Phut beaches.
Taling Ngam beach is on the west side of the island, south of the port harbouring ferries traveling between Don Sak port and Koh Samui. It is one of the most well-known beaches, and the best place to watch the sunset on Koh Samui. Koh Si and Koh Ha are located offshore, and the sun sets between the two islands, gradually disappearing from the horizon into the sea, creating a striking image. Boats may be chartered to travel to Koh Si and Koh Ha for diving or a relaxing fishing expedition.
Mae Nam is a bay with an attractive seaside atmosphere and a long narrow beach of around 4km. The attractive, peaceful and quiet beach is suitable for relaxation and swimming, but the sea is deep and rough in places, so care should be taken when going into the sea. The west side of the beach is adjoined to Wat Na Pralaan, which may be visited on foot. The central part of the beach is the site of Mae Nam village, home to an old island community and featuring a market, restaurants, laundry shops, retail shops, diving and water-sports shops and a port harbouring boats bound for Koh Pha-ngan.
Choeng Mon beach is located at the end of the peninsula in the north-east of the island. It is a long, peaceful crescent-shaped beach lined by casuarina trees and coconut palms. The water is not too deep, and the sandy brown beach has a shallow incline, making it suitable for swimming. Many resorts are situated on the right side of the beach, but none on the left, and at low tide it is possible to walk to Koh Fan Noi. 
Bo Phut is a beautiful, peaceful crescent-shaped bay with a clean beach. Both sides of Bo Phut beach road are lined with shops, tour agencies and restaurants modified from Chinese houses, so the original Chinese community atmosphere still remains. The port offers high-speed ferry services from Koh Samui to Koh Tao, and a selection of restaurants serve fresh seafood. The beach is famed for its seafood, and is also the site of an old fishing village, with its long row of houses along the beach.
Lamai beach is situated on the east side of Koh Samui and is around 4km long. The second most visited beach after Chaweng, Lamai is a long clean white sand beach with an indigo sea, lined by coconut palms. Locals say that the beach is at its most magnificent, and the sea is at a depth suitable for swimming, between December to April and July to August, when most tourists visit Lamai beach. November to mid-December bring high waves, while from May to June, the sea is shallow and not suitable for swimming. 
Lamai beach is divided into north, central and south sections. North Lamai beach is a fishing village, while Central Lamai beach is most popular with foreign tourists, since the inner road running parallel to the beach abounds with nightlife venues and various conveniences such as shops, bookshops, and jeep and motorcycle hire shops. South Lamai beach is the location of the Grandfather and Grandmother Rocks (Hin-Ta Hin-Yai), which is the source of an interesting legend. 
Chaweng is the longest, most beautiful and most celebrated beach on Koh Samui. Around 7km long, the beach also offers a pristine fringing reef at its north end (near Chaweng Garden Restaurant), which it is possible to swim to from the beach, as it is very close to the shore. Just swim for around 5 minutes, and you’ll reach a 5m deep diving spot. May to October is the most suitable period for diving as the sea is calm and tranquil.
In the evening, the road running parallel to central Chaweng beach dazzles with neon from bars and nightclubs. If you enjoy nightlife, you won’t be lonely, especially on the way to the Reggae Pub in Soi Reggae, which is dense on both sides with pubs and bars. Chaweng beach also offers a plethora of international restaurants to choose from, including Indian, Japanese, German, Italian, Mexican, French eateries. Shops selling imitation products also abound, offering clothes, bags and CDs to browse through on an evening stroll. 
Koh Samui is one of the most popular Thai destinations for tourists, with a variety of beautiful sandy beaches to choose from for sightseeing and relaxation. Traveling there is easy. Tourists may choose to fly directly to the island or travel by land and then take a boat from Surat Thani, where many different types of boat offer ferry services. Four or five days should be spent unwinding on this island.
