On an island renowned for its pristine beaches and sapphire-blue sea, one might expect visitors to Koh Samui, Thailand, to spend all their time lounging on the sand. However, the lush rainforest holds equal appeal for adventurous travelers, and Expedia Australia's travel experts have the best tips to share. Whether on foot or by bike, this Koh Samui walking guide will help you discover hidden waterfalls, mysterious gardens, and breathtaking views.

Instructions and preparation

Before you set off through the treetops to a viewpoint high on the mountainside, there are a few things you should keep in mind. First and foremost, you'll need the right equipment. This means comfortable, hiking-appropriate shoes and suitable clothing. Leave your sandals and cotton T-shirts at your hotel on Koh Samui.

The rainforest is very humid, so breathable clothing is essential to stay cool and dry. Sunscreen and insect repellent are also mandatory for extended periods outdoors. A rain poncho is also recommended to be prepared for unexpected downpours.

Due to the midday heat, it is recommended to start the hike early in the morning or late in the afternoon. Be sure to bring plenty of water and a snack to keep you hydrated and energized along the way.

The best hikes on Koh Samui

Now that you're all set, it's time to lace up your running shoes and get going. Here are some of the island's most beautiful hiking trails – all of which can be explored with or without a local guide.

Easy hikes

Think of these one- to two-hour hikes more as leisurely strolls that even the most inexperienced hiker can fully enjoy.

The Hin Lad Waterfall Trail is a riverside path that gradually leads you uphill through the jungle to a picturesque spot where the river plunges into a pool. You are welcome to swim or just dip your toes in the water before heading back.

The Maenam Viewpoint Trail in Nathon South is another easy option. Normally, you would have to hike for hours to enjoy a sweeping view across the island. However, this trail offers a scenic viewpoint high up on the mountain rim.

Moderate hikes

These hikes will take approximately two to three hours. You will certainly need to exert yourself, but you don't need to be an experienced hiker to complete them.

The Magic Garden – also known as the Secret Buddha Garden – is a sculpture park created by the Buddhist practitioner Uncle Nim. The hike there through the dense forest can be steep and challenging in places, but it's well worth the effort.

After exploring the statues and the surrounding jungle landscape, you can embark on a separate, moderately challenging hike. A golden, reclining replica of the Reclining Buddha is located approximately 90 minutes away on another trail that begins at the Magic Garden. If both hikes seem too strenuous and you only wish to hike to the Reclining Buddha, you can drive to the Magic Garden and start from there.

Challenging hikes

For these three- to four-hour hikes, an early start is highly recommended. Bring plenty of water and make sure your camera is fully charged – you'll need it once you reach these majestic peaks.

The Nathon Mountain Ridge Trail takes you on a 13-kilometer loop through the entire Nathon Valley. Along the way, you'll pass coconut plantations, evergreen forests, and jungle vegetation – all ideal photo opportunities.

Another 13-kilometer hiking trail combines several of the easier and moderate hikes into one extended tour and takes you through a Buddhist temple. The Maenam Viewpoint-Wat Lamai-Magic Garden trail offers some of Koh Samui's most beautiful views. Maenam Viewpoint is a popular spot for overlooking the island. Continue climbing the tower of Wat Lamai, and on clear days you can even see the mainland. After enjoying the panorama, cross the Magic Garden, where you can admire Uncle Nim's artwork.

So, that's it. Hopefully, between beach walks, snorkeling trips, and sightseeing tours of Koh Samui, you'll also find time for these fantastic hikes. A day on the trails makes that beer in the pub all the more refreshing and that fish dish at dinner even more delicious.
