1. Klong Koi 5-Tier Waterfall and the Salak Phet Peak Trail

This is a dream trail for adventurers located in the southern part of Koh Chang, in the Salak Phet Bay area. What makes this trail special is that you'll experience both the cool refreshment of 'Klong Koi Waterfall' which has been discovered to have 5 tiers hidden in the dense forest. Each tier has its own unique beauty, with some featuring natural emerald pools perfect for a cooling dip to recover from fatigue. And if you have energy left, continuing onward to 'Salak Phet Peak', the highest point on Koh Chang at 744 meters above sea level, will reward you with panoramic views overlooking dozens of islands in the eastern sea.

This trail is quite challenging with steep sections in some areas. You'll walk through bamboo forests and small streams that crisscross the path. Along the way, you'll hear truly pristine natural sounds with barely any engine noise disturbing you. This journey typically takes a full day (approximately 6-7 hours), so preparing drinking water and lunch is crucial. And since the trail is complex, we recommend contacting an experienced local guide for safety and to gain in-depth information about rare plant species along the way.

2. Khao Laem: The most beautiful 360-degree viewpoint on the island

If you're looking for an Insta-worthy spot earned through sweat, Khao Laem is the answer. This trail reaches approximately 650 meters in elevation and is renowned as one of the most scenic hiking trails on the island. When you climb to the peak, the forest opens up leaving only grasslands and large rock formations where you can stand majestically above the clouds, with views of Salak Phet Bay and Salak Khok Bay curving below.

The Unseen quality of Khao Laem isn't just at the summit, but in the diversity of ecosystems you'll encounter along the way, from dark and dense rainforest to open mountain ridge forest with constant cooling breezes. On days with light fog, this peak looks like it's escaped from an adventure movie scene. Tour packages with guides usually include transportation and meals, which is an excellent option for tourists wanting a Full Option experience who don't want to get lost in potentially dangerous forests.

This is a conservation hiking trail recently opened and considered Epic level for Koh Chang. This 9.5-kilometer long-distance trail connects 'Than Mayom Waterfall' on the eastern side, crossing the island's central ridge to end at 'Klong Plu Waterfall' on the western side. It's a trail that combines history and natural abundance together, with the purpose of allowing tourists to experience the path once traveled by royalty in the past.

This trail passes through forest that has been closed for over 20 years, giving you a high chance of encountering rare wildlife and exotic plants. It's volunteer and conservation tourism that will completely change your perspective on Koh Chang.

4. Prau Talay Waterfall - A tranquil hidden gem

For those who don't want to hike all the way to mountain peaks but still want privacy and an Unseen atmosphere, 'Prau Talay Waterfall' is your destination. The trail starts from near Grand Laguna Resort in the south. It's a small waterfall but with very high privacy, as most tourists tend to overlook it and head to the main waterfalls like Klong Plu or Than Mayom instead.

Prau Talay Waterfall is special in that it's one of the waterfalls located closest to the sea, allowing you to experience both the ambiance of the rainforest and sea breeze at the same time. The surrounding atmosphere is covered with large trees and moss-covered green rocks. It's perfect for meditation, reading, or swimming in the small natural pool that's so clear you can see the rocky bottom. It's an excellent resting spot for those who want to truly escape the chaos.

5. Kai Bae Waterfall Top Tier

Kai Bae Waterfall may be known as a small waterfall near the village, but the real secret is the hiking trail heading to the 'top tier'. This trail has moderate slope and challenge level, requiring you to climb along rock formations and large tree roots. But the reward waiting at the top is immensely worthwhile because you'll see the waterfall dropping down below from a high angle, with lush green forest views surrounding you.

The top of Kai Bae Waterfall features a flat rock stream where water flows calmly before dropping down. It's a very photogenic spot and usually has no one to disturb you. If you come right after fresh rain, the water flow will be strong and create cool, refreshing mist. Visiting here requires special caution as the rocks can be slippery, but for Unseen enthusiasts, this is a must-check spot if you're staying on the western side of the island.
