Things to Do in Koh Samui: Beaches, Temples, Tours & Nightlife

Koh Samui is Thailand’s second-largest island and the gateway to the Gulf of Thailand’s island chain. Where Phuket attracts the masses, Samui draws travellers looking for something a half-step calmer — palm-fringed beaches, a golden Big Buddha on the hillside, morning yoga at a beachfront resort, and fresh seafood as the sun drops behind the coconut palms.

The island is ringed by a single coastal road (Route 4169, about 50 km), making it easy to explore. Chaweng is the busy east coast — nightlife, shopping, the airport. Lamai is a step mellower. Bophut (Fisherman’s Village) is the charm pick. And the north coast around Maenam and Bang Po is where you go to be left alone.

Koh Samui Highlights

• Best beach: Lamai Beach — less hectic than Chaweng, good swimming, beach bars

• Best day trip: Ang Thong Marine Park — 42 limestone islands, emerald lagoon, kayaking

• Best evening: Fisherman’s Village Walking Street, Bophut — Friday night market

• Best viewpoint: Overlap Stone (Hin Lad viewpoint) — panoramic sunset views

• Peak season: February-June (dry, calm seas)

Beaches

Chaweng Beach

The longest beach on Samui (7 km) and the most developed — hotels, bars, restaurants, and water sports lined up along the sand. The northern end is quieter; the central strip is where the action is. Good for: swimming, jet skiing, beach bars, nightlife access. The sand is fine and white, the water clear in high season.

Lamai Beach

Samui’s second beach — similar quality sand and water but with 30% fewer people. The south end has boulders and rocky coves for snorkelling. Hin Ta Hin Yai (Grandfather and Grandmother Rocks) are at the southern tip — phallic rock formations that draw a steady stream of giggling visitors. Good restaurants along the beach road.

Maenam Beach

The quiet north coast — long, palm-shaded beach with shallow water. Popular with families and long-stay visitors who want peace. Thursday night market in Maenam village. Budget-friendly accommodation compared to Chaweng.

Bophut (Fisherman’s Village)

Not the best swimming beach (narrow, some rocks), but the village behind it is Samui’s most atmospheric strip — old wooden shophouses converted into boutique hotels, restaurants, and bars. The Friday Walking Street is the island’s best market: live music, seafood grills, handmade goods, and a genuinely good atmosphere.

Temples & Culture

Big Buddha (Wat Phra Yai)

The 12-metre golden seated Buddha on a small island connected by causeway is Samui’s most recognisable landmark. Visible from the air as you fly in. The temple complex around the base has smaller shrines, fortune sticks, and a bell tower. Free entry. Dress respectfully (covered shoulders and knees — rental sarongs available). Best visited in the morning when the light hits the gold.

Wat Plai Laem

A colourful lakeside temple complex with an 18-armed Guanyin statue rising from the water. Less visited than Big Buddha but more photogenic. Feed the fish in the lake (10 THB for fish food). Free entry. 5 minutes from the airport.

Secret Buddha Garden (Magic Garden)

A hidden sculpture garden on a forested hillside in the island’s mountainous interior. Mossy Buddha statues, spirit houses, and animal figures scattered through the jungle. Reach it by 4WD only (the road is steep and unpaved). Tours run from most hotels (500-800 THB including transport).

Day Trips

Ang Thong Marine Park

Forty-two limestone islands rising from emerald water — Samui’s most spectacular day trip. Tours include kayaking through sea caves, snorkelling over coral reefs, hiking to the Emerald Lake viewpoint on Koh Mae Koh (the highlight — a saltwater lake surrounded by jungle-covered cliffs), and lunch on the beach. Full-day tours depart from Nathon Pier (1,500-2,500 THB). The park is closed November-December during monsoon season.

Koh Phangan

A 30-minute ferry hop from Samui. Visit for the Full Moon Party, or come any other day for empty beaches, yoga retreats, and a more bohemian vibe. Ferries run frequently from Nathon and Big Buddha Pier (200-400 THB each way).

Koh Tao

Thailand’s dive capital — 2 hours by ferry from Samui. Some of the cheapest PADI certification in the world (8,000-10,000 THB for Open Water). Even non-divers enjoy the snorkelling at Japanese Gardens and Mango Bay. Day trips available but an overnight stay is better.

Activities

Snorkelling & Diving

Coral Cove and Chaweng Noi have decent shore snorkelling. For better visibility, take a boat trip to Koh Tan (south coast, shallow reef, turtles) or the Ang Thong islands. Dive shops cluster in Chaweng and Bophut — Koh Tao trips available as day excursions.

Thai Cooking Classes

Several on the island, typically including a market visit and 4-5 dishes. Expect 1,200-1,800 THB for a half-day class. Look for classes that include southern Thai dishes (Massaman curry, fish cakes) for something different from the Chiang Mai standards.

Muay Thai

Multiple gyms welcome drop-in visitors. A single session runs 300-500 THB. Week-long training packages from 3,000 THB. Phetch Buncha Boxing Stadium hosts regular fights — an entertaining evening even if you have no training interest.

Spa & Wellness

Samui is a wellness destination — from 200 THB street-side Thai massage to luxury resort spas charging 5,000+ THB for a treatment. The island also has 51 retreats including yoga, detox, and meditation programmes. Browse Koh Samui retreats.

Nightlife

Chaweng is where Samui goes out at night — the beach road and Soi Green Mango have bars, clubs, and live music. Green Mango is the biggest club. Ark Bar on Chaweng Beach does beach parties with fire shows. Fisherman’s Village in Bophut is the mellow alternative — cocktails, live acoustic music, fairy-lit restaurants.

Getting Around

Songthaews: Shared pickup trucks follow set routes around the coast road. Flag one down and agree on a price (50-100 THB within one area, 100-200 THB between areas). Bargaining expected.

Grab: Works on Samui but fewer drivers than Bangkok. 150-400 THB for most trips.

Scooter rental: 150-300 THB/day. The island roads are well-maintained but hilly in the interior. Make sure your travel insurance covers motorbike riding.

From Bangkok: Bangkok Airways has a near-monopoly on direct Samui flights (1 hour, 2,500-5,000 THB). Budget alternative: fly to Surat Thani (1,200-2,000 THB) then bus + ferry combo (3-4 hours, 400-600 THB).
