Koh Samui is Thailand’s second-largest island and one of its most rewarding — a place where you can wake up to a quiet beach, spend the afternoon exploring a jungle waterfall, and end the evening watching the sun sink into the Gulf of Thailand from a rooftop bar. It has the infrastructure of a well-developed destination without losing the feel of a Thai island. Here’s everything you need to plan your trip.
Best Beaches in Koh Samui
Chaweng Beach
The most famous beach on the island — a long, curved stretch of white sand with clear water, a buzzing strip of restaurants and bars, and the best nightlife on Samui. If you want to be in the middle of the action, this is where to stay. It gets busy, especially in high season, but the beach itself is genuinely beautiful.
Best for: First-timers, solo travelers, nightlife lovers.
Lamai Beach
Samui’s second-longest beach is quieter than Chaweng but still has plenty of restaurants, bars and accommodation options. The water is excellent for swimming, and the vibe is a little more relaxed — good for couples who want a beach base without the full party scene.
Best for: Couples, mid-range travelers.
Maenam Beach
A long, quiet beach on the north coast that most package tourists never reach. Shallow water, gentle waves, and a peaceful atmosphere make it ideal for families with young children. Prices are lower here too — good value for a longer stay.
Best for: Families, budget travelers, longer stays.
Bophut — Fisherman’s Village
This is my favorite part of Samui. The old Fisherman’s Village on Bophut beach has been beautifully preserved — wooden shophouses converted into boutique hotels, wine bars and excellent restaurants, all along a quiet beach. The Friday Night Walking Street market here is one of the best on the island. A world away from Chaweng’s neon strip.
Best for: Those who want charm and atmosphere over beach action.

Top Things to Do in Koh Samui
1. Island Hopping — Ang Thong Marine Park
The Ang Thong National Marine Park is one of the most beautiful places in the Gulf of Thailand — a cluster of 42 islands with emerald lagoons, hidden caves and snorkeling spots that look like they were designed for a travel poster. A day trip from Samui is the best way to see it.
2. Snorkeling
The waters around Koh Samui and the nearby islands are excellent for snorkeling — clear visibility, healthy coral, and plenty of tropical fish. A guided snorkeling tour gets you to the best spots with equipment included.
3. Sunset Cruise
Watch the Gulf of Thailand turn gold as the sun sets from the deck of a boat. A sunset cruise is one of the most memorable ways to spend an evening on Samui — relaxed, beautiful, and a great way to see the coastline from the water.
4. City & Temples Half-Day Tour
Beyond the beaches, Samui has an interesting cultural side. A half-day city tour covers the island’s temples — including the famous Big Buddha — local markets, and viewpoints with panoramic views over the Gulf. A good way to spend a morning before the beach.
5. Na Muang Waterfall
Samui’s most impressive waterfall is in the jungle interior of the island — a short hike through the forest to a beautiful cascade with a natural swimming pool at the base. A refreshing break from the beach, and one of the island’s genuine natural highlights.
6. Big Buddha Temple (Wat Phra Yai)
A 12-metre golden Buddha sits on a small island connected to Samui by a causeway, overlooking the north coast. It’s one of Samui’s most recognizable landmarks and worth a visit — especially at sunset when the light is beautiful. Dress respectfully: shoulders and knees covered.
How Long to Spend in Koh Samui
3–4 days: Enough to settle into one beach area, do a day trip to Ang Thong, and see the main temples and waterfall.
5–7 days: The ideal length — time to explore different parts of the island, do multiple activities, and actually relax.
10+ days: Use Samui as a base and add day trips to Koh Phangan and Koh Tao.
Getting to Koh Samui
Samui has its own airport with direct flights from Bangkok (about 1 hour). Alternatively, take a train or bus from Bangkok to Surat Thani on the mainland, then a ferry across to the island.

When to Visit Koh Samui
Koh Samui is on the Gulf coast (east side of Thailand), so its seasons are opposite to Phuket and Krabi.
Best time: December to September — long dry season with calm seas and sunshine.
Avoid: October and November — this is Samui’s rainy season, with heavy storms and rough seas. Many resorts close during this period.
This is the big advantage of Thailand’s two coasts — when Samui is rainy (Oct–Nov), Phuket and Krabi are at their best. Plan accordingly.
Practical Tips
- Renting a scooter is the best way to explore the island — roads are good and distances are manageable.
- Grab works on Samui for taxis — always better than negotiating with tuk-tuks.
- Book accommodation early for December–February (peak season) — the good places fill up fast.
- The Friday Night Walking Street in Bophut is not to be missed.
- Dress respectfully when visiting temples — shoulders and knees covered.
