About Ang Thong National Marine Park

Ang Thong National Marine Park is a breathtaking archipelago of 42 limestone islands rising dramatically from the Gulf of Thailand. Famous for its emerald-green saltwater lagoon, panoramic viewpoints, hidden beaches, and crystal-clear waters, the park is a paradise for nature lovers and photographers. Beyond its stunning landscapes, Ang Thong is home to diverse wildlife, including playful dusky langurs, sea eagles, colorful tropical birds, and vibrant marine life, making every visit a memorable adventure both on land and at sea.

Is Ang Thong Marine Park Right for You?

Ang Thong Marine Park is famous for its breathtaking landscapes, dramatic limestone islands, and spectacular viewpoints. The highlights include hiking to the panoramic viewpoint on Koh Wua Ta Lap (a steep but rewarding climb) and visiting Koh Mae Ko to see the stunning Emerald Lake, a hidden saltwater lagoon surrounded by towering cliffs. The park is also home to wildlife such as dusky langurs, sea eagles, and colorful tropical birds. While most tours include snorkeling, the reefs are modest. If snorkeling is your main priority, Koh Tao & Koh Nang Yuan are better choices.

Perfect for you if you:

✅ Love scenery, photography, and wildlife
✅ Enjoy kayaking (does not apply to the Luxury Sail Boat option.)
✅ Want to explore multiple islands
✅ Like hiking to viewpoints

May not be ideal if you:

❌ Are looking for exceptional snorkeling (Koh Tao & Koh Nang Yuan trip is more recommended)
❌ Dislike steep climbs or lots of stairs

Boat Options

🚤 Speedboat Fastest

A speedboat is the quickest way to reach Ang Thong Marine Park, giving you more time to enjoy the islands. Another advantage is that you can step directly onto the floating pontoon when arriving at the islands, without transferring to a long-tail boat. However, the ride can be bumpy in choppy seas, and the faster journey means less time to sit back and admire the scenery along the way.

Speedboat trips are available from Koh Samui and Koh Phangan

⛴️ Big Boat Budget-Friendly 2-Day Option

The big boat offers a more relaxed, comfortable, and budget-friendly journey. With spacious seating and plenty of room to move around, you can enjoy the beautiful seascapes throughout the cruise. The trade-off is a longer travel time. Upon arrival, you'll transfer to a traditional Thai long-tail boat before walking onto the floating pontoon to access the islands.

✓ The only boat option that lets you split your visit over two days at no extra charge — stay overnight on Koh Wua Talap (accommodation booked separately with the national park)

Good to know: bungalows and tents on Koh Wua Talap are booked directly with the Department of National Parks, not through Click2Go. There are only a handful of bungalows available, so we recommend booking your accommodation as early as possible.

Kayaking is an optional add-on for the Big Boat (extra charge on top of the starting price).

Book Big Boat from Koh Samui

⛵ Luxury Sail Boat Premium

A luxury sail boat provides a similar travel experience to a big boat but with a more refined atmosphere. The vessel is beautifully designed, the onboard facilities are more stylish, and the overall journey feels more exclusive and relaxing. Like the big boat, you'll transfer to a traditional long-tail boat before reaching the floating pontoon and stepping onto the islands. There is no kayaking activity available for this boat.

Which should you choose?

• 🚤 Choose a Speedboat if you want the fastest trip and more time to explore the islands.
• ⛴️ Choose a Big Boat if comfort and a budget-friendly, leisurely cruise are your priorities. It's also the only option that lets you split your trip over two days at no extra charge — just book your overnight accommodation on Koh Wua Talap directly with the national park.
• ⛵ Choose a Luxury Sail Boat if you want to enjoy the journey itself in a more elegant and premium setting. This option does not include kayaking.

Hike to the Wua Ta Lap Viewpoints

The hike to the famous Wua Ta Lap Viewpoint (Pha Chan Charat Viewpoint) is one of the highlights of any Ang Thong Marine Park tour. Although the trail is only 500 meters long, it is steep and physically demanding, following a series of natural stone steps and rocky paths. Rope handrails are provided along much of the route to help you navigate the climb safely.

There are five viewpoints along the trail, allowing you to stop, rest, and enjoy increasingly spectacular views of the archipelago:

• 100 m – A gentle introduction with the first scenic overlook.
• 200 m – Wider views of the surrounding islands and coastline.
• 350 m – A stunning panoramic viewpoint that many visitors consider the perfect stopping point.
• 450 m – Higher elevation with even more expansive views.
• 500 m – The summit, offering the most breathtaking panorama of Ang Thong National Marine Park.

Reaching the 500-meter summit requires a good level of fitness and sure footing. Wear comfortable clothing and sturdy sports shoes with good grip, and bring drinking water, especially on hot days. If you're not comfortable with steep climbs, don't worry—the 350-meter viewpoint already offers an incredible panorama and is a rewarding destination for most visitors.

Tip: Wear comfortable shoes with good traction for the hike to the viewpoint, and don't forget to bring a bottle of drinking water.

Visit the Emerald Lake (Talay Nai) on Koh Mae Ko

One of the highlights of Ang Thong National Marine Park is a visit to Emerald Lake (Talay Nai) on Koh Mae Ko. This remarkable natural attraction is a hidden saltwater lagoon surrounded by towering limestone cliffs, creating one of the park's most iconic and photographed landscapes.

After arriving at the island, a short walk up a series of steps leads to a viewpoint overlooking the lake. The trail is well-maintained and suitable for most visitors, taking around 10–15 minutes at a comfortable pace. Along the way, you'll pass through lush tropical forest before reaching a viewing platform with spectacular views of the emerald-green water below.

Although it is often called a lake, Talay Nai is actually a saltwater lagoon connected to the sea through underground limestone tunnels. The vivid green color of the water, combined with the surrounding cliffs, creates a truly unique and picturesque scene.

Most visitors spend around 20–30 minutes on Koh Mae Ko, giving you enough time to admire the scenery, take photos, and enjoy the peaceful atmosphere before continuing to the next activity.

Highlights of Koh Mae Ko

• 💚 See the famous Emerald Lake (Talay Nai), a beautiful natural saltwater lagoon.
• 🥾 Enjoy a short, easy walk to a scenic viewpoint.
• 📸 Capture one of Ang Thong Marine Park's most iconic photo spots.
• 🌿 Experience the lush tropical forest and dramatic limestone landscape.

Good to know: The viewpoint is reached by climbing a number of steps, but it is much easier than the hike to the Wua Ta Lap Viewpoint and is suitable for most visitors with a reasonable level of mobility.

Kayaking at Ang Thong Marine Park

Kayaking is one of the most enjoyable ways to experience the natural beauty of Ang Thong Marine Park. As you paddle through calm, turquoise waters, you'll follow the coastline beneath towering limestone cliffs, explore quiet bays, and enjoy a unique perspective of the dramatic islands rising from the sea.

The kayaking location depends on the type of tour you choose:

• Speedboat tours typically offer kayaking at Koh Wua Ta Lap. Since this island is also home to the famous viewpoint hike, you'll need to manage your time if you want to enjoy both activities.
• Big Boat tours offer kayaking as an optional add-on (extra charge) around Koh Mae Ko (Emerald Lake Island). This allows you to enjoy a more relaxed paddling experience without having to combine it with the challenging viewpoint hike. Kayaking is not available on the Luxury Sail Boat.

The route is generally easy and suitable for beginners, following the sheltered coastline rather than crossing open water. Along the way, you'll paddle past impressive limestone formations, small beaches, and lush tropical vegetation. If you're lucky, you may even spot wildlife such as dusky langurs, sea eagles, or colorful birds among the cliffs and trees.

Whether you're looking for a peaceful outdoor activity or simply a different way to admire the spectacular scenery, kayaking is one of the highlights of an Ang Thong Marine Park tour.
