What is good to know if travelling to Koh Samui?

  • Fisherman’s Village is packed with restaurants, shops, market stalls and bars. There is an Irish bar, naturally, called The Irish Times. The Billabong Surf Club flies the Aussie flag.
  • Hua Thanon is a Muslim village on the south coast. While there are some restaurants and a wonderful beach, seeing the fishermen at work and looking at their beautifully decorated boats is the best thing.
  • The bonus to playing a round of golf on Koh Samui are the beautiful views. The Santiburu Samui Country Club on the north coast is an 18-hole, par-72 course. The Royal Samui Golf and Country Club is located next to Chaweng Beach and will be an 18-hole course. It’s nine holes at present. There are views of Lamai, Cheweng and the surrounding islands.
  • Samui Shooting Sport is close to Chaweng about 200 metres from the Tesco Lotus superstore. It’s a great place to let off some steam with, perhaps, an AK-47. Elephant trekking is a gentler option. It’s a great, slow, way to go into Koh Samaui’s jungly heart.
  • From the pier at Bophut beach you can take a boat to Ko Pha Ngan or take a day trip to the Ang Thong National Marine Park, which consists of 42 limestone islands with soaring mountains, sheer cliffs and dense, green forest.
  • Hin Ta and Hin Yai – Grandfather Rock and Grandmother Rock – provide a quirky photo op. The rocks, south of Chaweng beach, are shaped, suggestively, like male and female genitalia.
  • The Muay Thai stadium in Chaweng town is worth a visit to experience this traditional sport.
