[2025 Koh Samui ] Travel Guide for Ko Mae Ko (Updated Mar)

#hiddengems There are 42 islands in Thailand's Ang Thong Marine National Park. Ko Mae Ko, or Mae Ko Island, is one of the best for kayaking as the waters surrounding it are calmer due to its shape. It's also on this island where you can find the Emerald Lake - a super hidden lagoon accessible only by a hike up (~20 minutes) to the viewpoint, and THEN a steep and slippery trek downwards. The lake, known as Talay Nai, is a beautiful turquoise and even glimmering sapphire under the sun, and at different angles. It was quite emotional, even, to enjoy such a view and feel so small in a vast and extensive planet. The hike up was very manageable. Paths and steps were clear; plenty of railings and durable ropes to guide you. Proper shoes recommended for comfort. Getting here is easy - many tour companies organize day trips to Ko Mae Ko from Koh Samui, and they're relatively affordable. At Mae Ko, must-do is definitely kayaking. You can circle around small islets and get back to shore in less than 20 minutes. The sun might be glaring, but the calming waters and stunning limestone cliffs and rock formations will make the effort worth it. If you're hungry, there's a bar/restaurant/souvenir shop (combined into 1) on the shore. Overall, the Emerald Lake (or Blue Lagoon) is an exciting hidden gem located less than an hour's speedboat ride from Koh Samui. One can easily spend a day here, so come with plenty of thirst for adventure! Unforgettable experience ✨ #thailand #samui #nature #beach

Koh Mae Ko (Mae Ko Island) is located in Angthong National Marine Park. Most visitors or tourists prefer to rent a private boat to visit this island. In our case we booked from the internet and we went together with another group with a longtail boat. It features the emerald lagoon surrounded by lush green mountain. I feel so relaxed in this place. #passionpassport #beachlife #hiking #snorkeling #scenicspotguide #scenicspotphotoguide #mountainview #beaches #island #islandhopping #lagoon

Location: The Inner Sea at Mae Ko Island, Ang Thong National Marine Park This spot is usually included in tours of Ang Thong National Marine Park. When you arrive at Mae Ko Island, you need to hike up to the viewpoint to see the Inner Sea. The water is very beautiful, and you can see coral from the viewpoint. Note: Swimming is not allowed due to safety concerns and the depth of the water. Location: Ang Thong, Ko Samui District, Surat Thani
