Koh Samui

Koh Samui is a stunning island resort in the Gulf of Thailand, offering visitors the chance to experience outstanding beaches and a wide range of activities to suit all budgets. Located 700km south of Bangkok, Koh Samui is located in an archipelago of over 80 islands and is one of the most popular holiday destinations in Thailand.

Historically, Koh Samui was a sleepy paradise inhabited by fishermen and coconut harvesters who enjoyed the tropical rainforests and tranquility of the pale sands and crystalline waters which surround the island.  However, over the years, Koh Samui has combined its natural beauty with modern facilities to become a world-class travel destination offering something for everyone. Koh Samui’s beach resorts at Chaweng and Lamai provide outstanding restaurants serving delicious Thai and international cuisine as well as lively bars and nightclubs.

For those seeking a more relaxing holiday, Bo Phut offers the peaceful palm-fringed beaches and charming Chinese-style houses reminiscent of the sleepy origins of Koh Samui. Sports fans can enjoy Muay Thai training and golf, whilst Koh Samui also offers scuba diving and other watersports.  World-class kayaking is also available at nearby Ang Thong National Marine, which provides a perfect day trip from Koh Samui.  Holiday visitors to Koh Samui can also enjoy cooking classes, yoga instruction and a multitude of other leisure activities. The third largest island in the country, Koh Samui deserves its reputation as Thailand’s paradise island, effortlessly combining its natural charms with modern amenities and entertainment options to make it the perfect beach holiday destination.
