Top 10 Things to Do in Koh Samui (2025 Edition)

Koh Samui is one of Thailand’s most iconic islands—famous for its palm-fringed beaches, lush jungle interior, luxury resorts, lively markets, and incredible day trips. Whether you’re here for relaxation, adventure, or culture, Samui has something unforgettable waiting for you.

Here are the Top 10 Things to Do in Koh Samui to make the most of your visit:

1. Explore Ang Thong Marine Park

A must-see. This protected archipelago of 42 islands is packed with emerald lagoons, limestone cliffs, snorkeling spots, kayaking routes, and dramatic viewpoints. It’s one of Thailand’s most stunning natural wonders and best visited on a full-day tour.

2. Visit the Big Buddha (Wat Phra Yai)

Standing 12 meters tall on a small island off Samui’s northeast coast, the Big Buddha is one of the island’s most iconic landmarks. Go early for peaceful vibes or near sunset for gorgeous lighting and a cool breeze.

3. Wander Fisherman’s Village Walking Street

On Fridays, Bophut transforms into a lively street market filled with food stalls, handmade crafts, live music, bars, and beachside restaurants. Great for families, couples, or anyone who wants an easygoing night out.

4. Relax at Chaweng Beach

Chaweng is Samui’s most famous stretch of sand—a long, vibrant beach with clear waters, beach clubs, restaurants, and activities like jet skis and paddleboards. Early mornings are especially beautiful.

5. Take a Day Trip to Koh Phangan or Koh Tao

Samui is the perfect base for island-hopping.

Koh Tao → Best diving and snorkeling in Thailand.
Koh Phangan → Beautiful beaches, viewpoints, and cultural spots (not just Full Moon Party!).

6. Check Out the Secret Buddha Garden

Hidden in the hills of central Samui, the Secret Buddha Garden is filled with mystical stone sculptures and surrounded by jungle. Combine it with a 4x4 mountain tour for viewpoints overlooking the entire island.

7. Enjoy a Beachfront Massage

Nothing says “Thailand” like a traditional Thai massage right on the beach. Whether it’s Lamai, Bophut, Chaweng or Maenam, you’ll find plenty of clean, affordable massage spots with ocean views.

8. Visit Hin Ta & Hin Yai Rocks

One of Samui’s quirkiest landmarks, these naturally formed rock formations resemble… well, male and female anatomy. Fun, quick stop with nearby shops selling coconut ice cream and local snacks.

9. Experience Samui’s Waterfalls

The island’s jungle interior hides some beautiful waterfalls:

Na Muang 1 & 2 – the most famous, great for swimming.
Hin Lad Waterfall – peaceful hike through lush forest.

Best visited during or just after rainy season.

10. Join a Local Thai Cooking Class

Learn to make authentic Thai dishes like Tom Yum, Pad Thai, Green Curry, and Mango Sticky Rice. Classes often include a fresh market tour and are a delicious way to experience Thai culture.
