The major reason why people come to Samui is, quite simply, to enjoy the beaches. Even though the two main beaches of Chaweng and Lamai have generally suffered due to mass development over the past decade, they are still relatively impressive. Development has been thwarted slightly however, because of the island’s regulation governing height restriction.
Other than lying on the beach with a cold beer in hand and ogling at the babes and hunks sauntering past, there isn't all that much to see on the island. A certain pair of rocks on Lamai amuses some visitors, Bang Rak has a large but nondescript Buddha statue, and there are some waterfalls (notably Na Muang) of minor interest.
Chaweng Beach Chaweng is the major beach on Ko Samui and one that has developed tremendously since the early 1990s. Just 20 years ago the beach was home to just a sprinkle of wooden bungalows but now the place is swamped with 4-5 star hotels, Italian pizza joints, Irish pubs and even go-go bars. In fact, Samui’s nightlife is becoming legendary but unfortunately not always attracting the best standard of tourist. Chaweng’s once ‘hippy’ only backpackers have given way to a lot of ‘lager louts’. But if it’s a rowdy reckless party scene you are after, then Chaweng is the place for you.
Lamai Beach Like Chaweng, Lamai has transformed from a ‘hippy’ hangout into a fun, party place packed out with bars and exciting nightlife. The beach though, is still in better condition than Chaweng and the place doesn’t get quite so crowded. If it’s a quiet relaxing location you are after, then Lamai won’t be the ideal place for you. At the southern end of Lamai, there are some odd-looking rock formations.
Grandfather and Grandmother stones (Hin Ta and Hin Yai) - two stone formations nearby each other - one looking like an erect penis, the other looking like a vagina, hence their names. Located south-west of Lamai Beach, just off the 4169 ring road. There are many souvenir stands there, but most notable is the special candy which visitors can try for free - don't hesitate, it's worth a taste.

Maenam Beach This quite beach, located in the north of the island is decent enough for swimming and sunbathing especially for families with children due to the shallow water.
Bophut Beach Bophut, situated in the north of the island, is a popular starting point for diving tours. The place isn’t in any way as developed as Chaweng but there are still plenty of restaurants, shops and bars.
Choengmon Beach Choengmon is located in the North-East of Samui just 10 minutes from Chaweng. Unlike the latter however, it is a perfect place for relaxing.
Big Buddha Beach Located in the north-east of Samui, Big Buddha offers visitors good swimming and lovely views. The area has developed a lot over the past few years and there are now a plentitude of restaurants, shops and bars.
Na Thon - The island's major seafront settlement where shops, restaurants and tour agencies are concentrated.
Namtok Hin Lat – This waterfall is easily accessible by car. Some of the numerous tiny levels have a large basin for swimmers.
Namtok Na Mueang – A local road leads to the Na Mueang 1 Waterfall. A walk of about 30 minutes ends up at the more scenic Na Mueang 2 Waterfall. Purple rocks surround the stream of water, which gushes in from an impressive height of around 79 meters.
Ban Lipa Yai – This village grows high quality fruits, including rambutan, durian, mangosteen and the famed langsat.
Old House – This Chinese-style house, aged almost 200 years, represents Samui’s cultural identity. Grandpa Si and Grandma Maen Hancharoen, the present owner, open the house to visitors.
Other island attractions include coral beds at Laem Set and Thong Takhian; the phallic rock formations at the southern end of Lamai Bay; the nearby butterfly garden and aquarium; a snake farm; a monkey theatre at Bo Phut and a massive seated Buddha image on Fan isle.
Wat Khunaram Ko Samui This temple is the island’s most famous temple for its mummified monk on display. The mummy sits upright in a glass casket and devotees offer it flowers and incense. The mummy is in fact the body of a very revered former abbot of the temple who was also a meditation master that was able to predict his own death.
Samui Aquarium and Tiger Zoo Ko Samui Located at Ban Harn beach, the Samui Aquarium and Tiger Zoo offer a fun day out for the family. The undersea world of the aquarium has an amazing collection of tropical fish and other vibrant aquatic animals such as turtles and colorful coral. The tiger zoo is home to Bengal tigers and leopards. For those who are daring enough, they can have their photograph taken with the awesome animals. The Samui Aquarium and Tiger Zoo are open daily from 9 am till 6 pm.
Big Buddha Temple (Wat Phra Yai) Also known as the Big Buddha Temple (Wat Phra Yai), has a 15 meter tall statue of the Buddha. It was built in 1972 and is located in the north of the island.
Laem Sor Pagoda Ko Samui This chedi (pagoda) situated at Laem Sor temple is one of the most important shrines on Ko Samui. The structure with its yellow tiles which gives off a golden aura is quite impressive.
Samui Butterful Garden / Insect Museum This butterfly garden can be found in the south-east of the island. There is a huge collection of different butterflies, some quarter of a meter wide. The visitor can also enter the insect museum nearby to see a variety of rare bugs and a bee house.
Secret Buddha Garden This beautiful garden was made by a 76 year-old Ko Samui fruit farmer in 1976. It is surrounded by lush jungle, rocky hills and is adorned with sculptures depicting both humans, in various poses, as well as various deities. Since the garden is the highest point on the island, there are also some awesome views to be had. Organized tours to the garden last for about 2 hours.
Monkey Shows These shows can be enjoyed at the open-air theater on the main road behind Bophut beach. The entertainment also includes performing elephants
