Koh Samui, ประเทศไทย - Complete Travel Guide

The island's diverse landscape includes stunning waterfalls, coconut plantations, Buddhist temples, and some of Thailand's most beautiful beaches. While Koh Samui has evolved from a quiet fishing community into a world-class destination, it has managed to retain much of its authentic Thai charm alongside international sophistication.

The island serves as an excellent base for exploring nearby attractions like Ang Thong National Marine Park and the famous Full Moon Party on neighboring Koh Phangan.

Top Things to Do in Koh Samui

Beach Hopping and Water Sports

Explore Koh Samui's stunning coastline, from the bustling Chaweng Beach with its white sand and vibrant atmosphere to the quieter Lamai Beach perfect for relaxation. Engage in various water activities including snorkeling, kayaking, jet skiing, and stand-up paddleboarding in the island's crystal-clear waters.

Booking Tip: Water sports equipment rental costs 500-1,500 THB per hour depending on the activity. Book through beachfront operators for better prices (usually 20-30% less than hotel bookings). Best conditions are during morning hours (8-11 AM) when waters are calmer and visibility is optimal.

Ang Thong National Marine Park Day Trip

Take a boat excursion to this stunning archipelago of 42 islands featuring dramatic limestone cliffs, hidden lagoons, and pristine beaches. The park offers excellent snorkeling opportunities, hiking trails to viewpoints, and the famous Emerald Lake (Talay Nai) on Mae Koh island.

Booking Tip: Full-day tours cost 1,800-2,500 THB including lunch, snorkeling gear, and transfers. Book with reputable operators that use speedboats rather than longtail boats for comfort and time efficiency. Tours run daily except during rough weather (typically September-November).

Temple and Cultural Exploration

Visit the iconic Big Buddha Temple (Wat Phra Yai) with its impressive 12-meter golden statue, and explore Wat Plai Laem with its colorful 18-arm Guanyin statue. These sacred sites offer insight into Thai Buddhist culture and provide stunning photo opportunities with panoramic island views.

Booking Tip: Temple visits are free, but donations are appreciated (20-100 THB). Visit early morning (7-9 AM) or late afternoon (4-6 PM) to avoid crowds and heat. Dress modestly with covered shoulders and knees - sarongs are available for rent at temple entrances for 50 THB.

Jungle Safari and Waterfall Adventures

Explore Koh Samui's lush interior on 4WD jungle safaris visiting hidden waterfalls like Namuang and Sekumpet Falls. These adventures combine off-road driving through coconut plantations and rainforest with swimming in natural pools and elephant encounters at ethical sanctuaries.

Booking Tip: Half-day safari tours cost 1,200-2,000 THB per person including hotel transfers and refreshments. Choose operators that prioritize animal welfare and avoid elephant riding. Best time is during dry season (December-April) when trails are more accessible.

Sunset Dining and Night Markets

Experience Koh Samui's culinary scene at beachfront restaurants offering fresh seafood with spectacular sunset views, then explore vibrant night markets like Fisherman's Village Walking Street. Sample authentic Thai street food, shop for local handicrafts, and enjoy live music performances.

Booking Tip: Night markets operate on specific days (Fisherman's Village on Fridays, Lamai on Sundays). Street food costs 50-150 THB per dish, while beachfront restaurant meals range from 300-800 THB. Make dinner reservations for sunset viewing spots, especially during peak season.

Getting There

Koh Samui is accessible by air and sea, with Samui Airport being the most convenient option, served by Bangkok Airways with direct flights from Bangkok, Phuket, and other major cities (flight time 1.5 hours from Bangkok, costs 3,000-8,000 THB). Alternatively, you can take a bus or train from Bangkok to Surat Thani (8-12 hours, 500-1,500 THB) followed by a ferry to Koh Samui (1.5-2.5 hours, 150-400 THB depending on ferry type). The combination journey is more economical but takes significantly longer, while flying offers convenience and time savings.

When to Visit

The best time to visit Koh Samui is during the dry season from December to April, when you'll enjoy sunny skies, calm seas, and minimal rainfall - perfect for beach activities and water sports. This period also coincides with peak tourist season, so expect higher prices and crowded beaches. May to October brings occasional rain showers but also fewer crowds and better accommodation deals, with September and October being the wettest months. November marks the transition period with improving weather conditions and is often considered ideal for those seeking good weather with fewer tourists and moderate prices.

Insider Tips

Rent a scooter to explore the island's hidden gems, but always wear a helmet and carry your international driving license as police checkpoints are common, especially near popular beaches
Visit temples and cultural sites early in the morning (before 9 AM) to avoid crowds and intense heat, and always dress respectfully with covered shoulders and long pants or skirts
Book restaurant reservations in advance during peak season (December-March) and ask for sunset-facing tables at beachfront establishments for the best dining experience with spectacular views
