Hiking in Koh Samui: exploring the island through its most beautiful trails
What are the must-visit hiking trails in Koh Samui?
Hiking in Koh Samui offers various themes, from waterfalls accessible for families to more demanding jungle trails. Here are the routes that deserve special attention.
Na Muang, the iconic waterfalls of southern Koh Samui
The Na Muang waterfalls are the most famous meeting point for hikers on the island. Located in the central-south, they are available in two levels: Na Muang 1, easily accessible and ideal for a swimming break, and Na Muang 2, taller and more impressive, which takes about 1h30 to reach via a forest trail. The Na Muang waterfalls are even more spectacular in the rainy season, when the flow of the waterfall is at its maximum. Wearing appropriate shoes is essential on this route, as the rocks can become particularly slippery. The view of the waterfalls leaping from the mountain is well worth the effort.
Hin Lad, an immersion in the heart of the tropical forest
For a moderate level hike, the Hin Lad waterfall offers a route of about 2.6 km that crosses lush vegetation, punctuated with flowers, ancient trees, and a discreet but present fauna. The trail starts from the Wat Namtok Hin Lad temple, adding a cultural dimension to the walk. The arrival at the waterfall and its natural pool offers a welcome moment of serenity, ideal for a cool break after the effort. A route that is highly recommended for families or travelers wishing to enjoy some serenity without straying far from the island's infrastructure.
Secret Buddha Garden and the panoramic viewpoints
Perched in the heights of Koh Samui, the Secret Buddha Garden is a rare place that combines hiking and cultural discovery. The path to it crosses a durian plantation and dense vegetation before revealing statues carved into the rock, in both a magical and peaceful setting. For panorama lovers, the viewpoint of Khao Hua Jook, located in the north of the island, offers a 360° panoramic view of the sea, the airport, and the surrounding islands. A breathtaking spectacle, especially at sunset. The short and accessible route is suitable for all levels.

What is the best time to hike in Koh Samui?
The climate of Ko Samui directly influences hiking conditions. The island experiences two distinct seasons that are essential to consider before planning hiking trips.
| Period | Climatic Conditions | Recommendation |
|---|---|---|
| January – April | Dry weather, moderate heat | Ideal for hiking |
| May – June | Start of the rains, lush vegetation | Possible with precautions |
| July – September | Intermittent rains | Slippery trails |
| October – December | Main rainy season | Not recommended for difficult trails |
The optimal window is between January and April, with cool mornings and trails that are safe to navigate. Difficult hikes, like the Khao Nui loop, which crosses bamboo forests and wet zones, are particularly not recommended during heavy rainfall periods.
Advice from our Travel Planners: set off early in the morning to enjoy cooler temperatures and avoid the crowds on the island's most popular trails.
How to properly prepare for a hike in Koh Samui?
Hiking in a tropical environment requires different preparation than alpine mountain hiking. A few well-thought-out elements beforehand can help you approach hiking trails with confidence and fully enjoy every detail of the journey.
Essential equipment in the tropics
Wearing walking shoes with a non-slip sole is the first precaution to take, especially on wet trails near waterfalls. It is also advisable to plan for:
- Enough water, as the heat can be intense from mid-morning;
- An essential mosquito repellent in the dense forest;
- A lightweight and breathable pair of pants for trails in thick jungle;
- A hat and sunscreen for uncovered areas and exposed viewpoints.
Trails suited to every hiker's profile
The hiking trails at Ko Samui cater to all profiles. Beginners and families enjoy the paths of Na Muang 1 or Khun Si waterfall, short and accessible, offering beautiful discoveries without significant physical commitment. Intermediate hikers naturally turn to Hin Lad or the Secret Buddha Garden, lasting two to three hours. Finally, for advanced profiles, the Khao Nui loop — 9.3 km and over 600 meters of elevation gain — presents a real sporting challenge at the heart of the jungle. Each detail of this trail, from bamboo forests to open ridges, provides unforgettable strong moments.
To go even further, an excursion to the Mu Ko Ang Thong National Marine Park from Koh Samui adds to the experience with a hike on Mae Koh Island and a view of the Emerald Lake, one of the most beautiful hidden destinations in the region.
