Ang Thong Islands National Marine Park
Located 20 km northwest of Koh Samui, the Ang Thong Islands National Marine Park is popular for its fascinating beaches, caves and coral formations. Comprising over 40 islands, some oddly shaped, it is abundant in marine resources and stunning for its limestone cliffs and hidden lagoons.

The largest island in the group is Wua Ta Lap,  site of the park office and the Tham Bua Bok cave, visited for its spectacular stalactites and stalagmites. Another popular island in the group, Mae Ko, is known for its pristine beach and emerald saltwater lake. The national park does not allow a night stay. And one has to join a tour group to visit the place.

Buddha Footprints
Another revered site on the island, the Buddha Footprints is a bit tough to reach. There are no big signs posted and so finding this attraction will be part of the adventure. Take Route 4170 and turn to the road leading to the Butterfly Garden. Go up the concrete slope on the left. The Buddha Footprints are on a hilltop shrine which you can reach after negotiating a total of 163 steps. You should find four footprints engraved one on top of the other. The view up there is breathtaking.

Na Muang Waterfalls
A short drive from Nathon Town will bring you to the first of a pair of waterfalls. The first cascade, almost 20 meters high, can be reached by car up an unpaved road. The second, the tallest at 80 meters, can be reached through a half-hour uphill trek.

Picturesque Koh Pha-ngan
JUST 20 km. north of Koh Samui and a short boat trip away, Koh  Pha-ngan is a mountainous island ringed by 18 secluded bays that offer ideal getaways. Many of its beautiful beaches are accessible only by boat, though pick-up  trucks and motorbikes also ply the island’s rough roads. Its most famous beach is Hat Rin, in the southest corner of the island, which is the location for the world-famous full moon parties.

The Big Buddha
Located on the northern coast of the island, this 17-meter-tall statue is a popular shrine and meditation center. The gaudy bazaar within the temple grounds offers souvenirs – everything from T-shirts and hats to protective amulets. [VIDEO ]

Naga Pearl Farm
Just 4 km south of Samui is a small island called Koh Matsum. There you can see first hand how pearls are cultured. Usually, tours include a Thai lunch on the island and, of course, a visit to the Naga Pearl Shop where all varieties of pearls and pearl products are offered.

Hin Ta-Hin Yai
Meaning “Grandfather and Grandmother Rocks”, these unusual rock formations, named for their similarity to male and female sexual organs, can be found at the south end of Lamai beach, and are among Samui's most photographed attractions.

Koh Nang Yuan
Agroup of three little Virgin Islands, Koh Nang Yuan is close to the northern side of Koh Tao. The three islands are joined together by a three-way stretch of pure white beach. The waters around it offer excellent diving and snorkeling because of their wide variety of coral formations and marine fauna. Accommodation and facilities are available on the island group. To reach it, there is a daily boat service from Koh Tao.

Paradise Park Farm
Sitting on a beautifully preserved verdant forest, Paradise Park Farm is developed over four years, originally as a bird zoo with hundreds of bird species including parrots, love birds, parakeets and macaws. Now, this park perching on one of the island's highest mountains is home to Molly and Mommaem, two parrots that can talk to visitors in both Thai and English.
