Koh Samui

Samui island is a rare gem. Preserving the idyllic simplicity of a tropical hideaway, it is characterised by beaches of powdery white sand backed by many hotels and bungalow resorts. all beach bungalows have their own restaurants; small establishments are becoming increasingly rare. Fresh seafood and tropical fruits are the natural specialities of Samui, with emphasis on coconut sauces, though you’ll find menus sufficiently varied to cater to all tastes. The island, thailand’s third largest, measuring 22 kilometres at its widest point and 26 kilometres in maximum length, is one of a group of more than 80 tropical islands, only a few of which are inhabited.

A mountain ridge runs east to west; most of the hinterland comprises forested hills. The rich hues of wild vegetation are dappled with the contrasting greens of coconut palms and emerald paddy. The most developed bays are Chaweng and lamai, both on the east coast and featured as anchorages here.

Koh Samui

Principal among Samui’s natural sights are two picturesque waterfalls, Hin Lat and Na Muang; on neighbouring Koh Fan, connected to Samui by a causeway, is Wat Hin Ngu temple and meditation centre. At the southern end of Lamai Bay are the phallic granite rock formations of Hin Ta and Hin Yai. a 50-kilometre concrete and tar ring-road skirts Samui’s coastline, giving ready access to all beaches and the administrative centre of Na Thon, where most of the ferries arrive. the best transport is a motorbike which can be readily hired. In some areas, Samui retains its charm, but the ribbon development along the main ring-road is almost unbroken. Shops and supermarkets are found all over the island, while the majority of the nightlife is concentrated in Chaweng and lamai.

It is said that around four million coconut trees grow on Samui, a resource that used to be the island’s economic mainstay. Fruit crops and fishing were once the only other industries, yet today tourism is the main source of income. We list only the main anchorages, although there are many other options (see thai Chart 243).

  • A


140 miles from Songkhla

AO NATHON. 9° 32.188N, 99° 55.770E

Anchor in 7-10 metres well clear of the jetties. Nathon, the main town on the island, offers a market as well as shopping, banking, postal and other facilities. This is also where you go to deal with Customs and immigration. The main jetty is designed for fast passenger and car ferries, the local fishing fleet and bulk transport. Fuel and water are available on the jetty by arrangement only.

  • B


5 miles from ao Nathon, Samui

AO NASAi. 9° 28.767N, 99° 55.479E

This is the location of another car ferry terminal from Donsak, and it is not particularly recommended unless you are meeting passengers from the ferry.

  • C


11 miles from ao Nathon, Samui

KOH KAtEN. 9° 22.450N, 99° 57.441E

approaching from the east beware of the unmarked rocks just past Lamai Beach. anchor between the islands in 5-6 metres on a muddy bottom, clear of the fringing reef on Koh Katen’s east coast. the approach from the west is clear and deep, following Koh Katen’s north coast.

With a small resort ashore, this is a pleasant and secluded overnight spot or an ideal day destination from the main island. There are trails through the mangroves leading to caves ashore.

  • D


18 miles from ao Nathon, Samui

AO LAMAI. 9° 26.834N, 100° 3.255E

The best anchorage is in 6-8 metres on a sandy bottom in the middle of the bay. Take care to avoid the sand and fringe coral outcrops to the northwest of the bay. the anchorage may become uncomfortable in the southwest season due to ground swell.

Ao Lamai is the second-most-developed bay on the island, with plenty of action ashore. accommodation of all types is available, together with the usual minimarts, bars, discos and restaurants.

  • E


21 miles from ao Nathon, Samui

AO THONG TAKIEN. 9° 28.637N, 100° 4.121E

This small indention in the coast north of the headland makes a nice lunch stop and is used as such by many local fishing boats. Anchor outside the bay in 10 metres on sand, as the inner bay has a rocky bottom.

  • F


20 miles from ao Nathon, Samui

AO CHAWENG. 9° 31.082N, 100° 3.749E farawayfrom: 

The main tourist bay on Samui, ao Chaweng is separated by a rock formation into two beaches: Chaweng Noi (southern end) and Chaweng Yai (northern end).

The gradually sloping sandy bottom permits anchorage in 5-10 metres anywhere in the bay. In the southwest season, even in quite strong prevailing westerlies, a ground swell from the east can make this anchorage uncomfortable.

Major hotels, resorts, bungalows, restaurants, shops and discos sprawl along the road behind the beach. The main part of town is at the northern end. Towards the southern end of Chaweng Yai, the red roofs of the Centara Samui Resort can be clearly seen. Next door to the north is tradewinds by Lawana.

Centara is the headquarters for the Koh Samui Regatta, raced each year in May; tradewinds used to be a yachtie-owned and yachtie-friendly resort with fresh water tap on the beach. It has changed hands recently we have not been able to confirm to to what extent the yachtie-friendliness lives on.

Transport can be arranged by local bus or taxi from the road behind; Nathon is about 45 minutes away.

  • G


15 miles from ao Nathon, Samui

HAAD CHOENG MON. 9° 34.586N, 100° 5.131E

This is a reasonable daytime anchorage, affording access to the resorts ashore, but it is not suitable for overnight stays due to the rocky bottom. anchor in 8-12 metres well clear of the beach.

  • H
  • I
  • J


12 miles from ao Nathon, Samui

BANGRAK. 9° 34.394N, 100° 3.645E BOPHUT. 9° 33.498N, 100° 3.058E MAENAM. 9° 34.612N, 99° 59.952E

One large bay divided by a rocky promontory forms Bo Phut to the west and Bang Rak to the east. these bays are shallow, only 4 metres up to a mile offshore with anchorages on a sandy bottom in 2-4 metres. they offer the best protection from swell and wind during either season.

Approaching either bay from the northwest, beware of the reef at the western end. arriving from the east, the passage between Koh Som and the headland has a depth of 4 metres. In the east of the bay are several wooden and concrete jetties operated by tour companies where fuel and water can be arranged.

These north-coast beaches developed more recently than Chaweng and lamai and are less built up. in Bang Rak, look for the huge Buddha on Koh Fan, the island north of haad Bang Rak. This bay is directly on the approach path of the airport so it can be a little noisy. There is a large concrete ferry pier in the southwest corner of the bay which is deep enough to go alongside.

Ashore in each bay you’ll find clusters of small resorts and bars and a variety of small shops and local markets along the road. Many restaurants and small resorts line the bay. Local boats offer passage north across Chong Samui to Koh Phangan. A jetty with water is tucked in near the big Buddha at Pecherat Marina, Bang Rak.

Further west at Maenam, anchor in 4-6 metres on a sandy bottom. Beware of the submerged rock off laem Na Rang.

The Five Bird’s Nest islands

9° 25.769N, 99° 53.827E

On the southwest corner of Samui are five islands where the locals collect bird’s nests. The waters around the islands are deep, so this is not one of our recommended overnight anchorages although day anchorage can be found on the eastern side of Koh Mae tap.

on the southwest side, shelter can be found from strong winds without dropping the pick. there is a cave that runs right through the island. Koh Bon is great spot for a swim to cool off.

Many small shacks cling to the steep cliff faces and bamboo scaffolding used by the nest collectors can be seen rising to the top of the sheer rocks.
