Upon landing at Samui Airport, I was greeted by a garden-like outdoor airport and coconut palms. Koh Samui is a coconut island floating in the Gulf of Thailand, renowned for its Chaweng Beach and Ang Thong Marine Park. To put it simply, the most fulfilling way to spend 4 nights and 5 days in Koh Samui is to alternate between active days like Ang Thong hopping and island tours and relaxing days at the beach and resorts. Day 1 is for acclimatization in Chaweng, Day 2 is for Ang Thong Marine Park, Day 3 is for Big Buddha and island tour, Day 4 is for Lamai and resort relaxation, and Day 5 is for last-minute shopping before departure. For Korean travelers from Seoul/ICN, it takes about 8-9 hours with a layover in Bangkok, and a budget of 900,000 to 1,500,000 KRW per person (based on mid-range options) is sufficient. I’ll share my experience, including the opposite rainy season compared to other parts of Thailand and the island itinerary.

Day 1 — Acclimatization at Chaweng Beach and Night Market
On the first day, it’s best not to overdo it. I strolled along the lively Chaweng Beach, and in the evening, I enjoyed seafood and tom yum goong at the restaurants and bars along Beach Road. Chaweng is a bustling area filled with restaurants, massages, and nightlife, making it perfect for acclimatization on the first day. A massage costs around 300 to 400 baht (approximately 12,000 to 16,000 KRW) for an hour.
Day 2 — Hopping and Kayaking at Ang Thong Marine National Park
The highlight of my Koh Samui trip was Ang Thong Marine National Park. It consists of 42 limestone islands, where I enjoyed kayaking and snorkeling after entering by boat, and climbed to a viewpoint to overlook the emerald Talay Nai lagoon. A full-day tour costs around 1,500 to 2,500 baht (including lunch and equipment). Don’t forget to bring seasickness medication and sunscreen.
Day 3 — Big Buddha, Koh Phangan, and Na Muang Waterfall (Island Tour)
On the third day, I took a tour around the island. The itinerary included the 12-meter golden statue Big Buddha (Wat Phra Yai), the naturally shaped rock formations Koh Phangan (Grandfather and Grandmother Rocks), the jungle Na Muang Waterfall, and the charming Fisherman’s Village (Bophut). A half-day to a full day is sufficient to explore by rental car or with a driver.
Day 4 — Relaxation at Lamai Beach and Resort
The key to a relaxation trip is to 'take a day off.' On the fourth day, I enjoyed a peaceful day at Lamai Beach, which is quieter than Chaweng, or relaxed by the resort pool and spa. Koh Samui has many pool villas and resorts, making it perfect for relaxation. In the evening, I wrapped up my day with coconut desserts and seafood, fitting for a coconut island.
Day 5 — Last Shopping and Departure
On the last day, I kept it light according to my flight schedule. I shopped for Thai snacks, coconut oil, and souvenirs at the Chaweng Night Market or Central Festival, and indulged in one last massage. I wrapped up my trip leisurely at the garden-like Samui Airport.
