Overview
Lardwanorn Waterfall (also frequently spelled Lat Wanon) is one of Koh Samui’s most authentic “hidden gems.” Tucked away on the island’s tranquil west coast near Lipa Noi, it offers a stark contrast to the highly commercialized Na Muang falls. This isn’t just a single drop; it’s a sprawling, multi-tiered complex of rock formations and gentle cascades that flow through dense, primary jungle and local plantations.
The Lardwanorn loop is perfect for those who seek solitude and a raw connection with nature. Unlike the east coast attractions, you won’t find souvenir stalls or paved walkways here. Instead, you’ll find a rugged trail that rewards adventurous hikers with cooling natural pools and spectacular views of the Gulf of Thailand from its higher elevations.
Trail at a Glance:
- Distance: ~2.5 km (full loop exploration)
- Duration: 1 – 1.5 hours
- Difficulty: Easy to Moderate
- Highlights: Tiered cascades, panoramic views, jungle solitude
- Entry Fee: Free (occasional 20-30 THB parking fee)
Trail Details — What to Expect
The experience at Lardwanorn begins even before you reach the water. The entrance path takes you through a working landscape of coconut and banana plantations, providing a glimpse into the agricultural life of Samui that existed long before tourism.
The Initial Path
The first 10 minutes of the trail are relatively flat and easy. The path follows the natural line of the stream, shaded by a canopy of diverse tropical trees. This section is suitable for almost everyone and leads directly to the first few levels of the waterfall.
The Jungle Incline
As you push beyond the first level, the trail becomes more distinctively a “hike.” The terrain shifts to a mix of dirt paths and rocky scrambles. You will need to navigate around massive granite boulders and use tree roots as natural steps. The air here is noticeably cooler than on the coast, though the humidity of the dense jungle remains high.
Exploring the Tiers
Lardwanorn is unique because its “waterfall” is actually a long series of stepped rock formations.
- Level 1-2: These are the most accessible areas. The water here forms shallow pools that are ideal for families with children or those just looking to splash their feet.
- The Upper Tiers: To reach the higher levels, you’ll need to follow the trail upward. This section requires sturdy footwear as the rocks can be extremely slippery, especially after a rain shower.
- The Viewpoint: At the very top of the trail, the jungle opens up to reveal a stunning panoramic view. On a clear day, you can see all the way to the mainland and the distant islands of the Ang Thong National Marine Park.
Difficulty & Duration
| Section | Time | Difficulty | Terrain |
|---|---|---|---|
| Entrance to Level 1 | 10 min | Easy | Flat dirt path |
| Level 1 to Upper Tiers | 20-30 min | Moderate | Steep, rocky, roots |
| Full Loop Exploration | 1.5 hours | Moderate | Varied |
The Lardwanorn loop is rated as Easy to Moderate. While the distance is short, the vertical gain and the technical nature of the rocky sections in the upper tiers mean it requires a basic level of fitness and balance.
Getting There
Lardwanorn is located off the main ring road (4169) on the west side of the island, approximately 3.8 km south of Nathon.
- Look for the Sign: Watch for a small, slightly weathered sign that says “Wanrorn Waterfall” or “Lat Wanon” near the junction for Lipa Noi.
- The Access Road: Follow the narrow concrete road inland for about 1.5 km. You will pass local houses and plantations.
- Parking: The road ends at a small dirt clearing where you can park your scooter or car. Locals may sometimes collect a small fee (20-30 THB) for parking and maintenance.
Best Time to Visit
Timing is critical for Lardwanorn, as it is a highly seasonal waterfall.
| Season | Months | Rating | Condition |
|---|---|---|---|
| Monsoon | Oct – Dec | ★★★★★ | Peak flow; very lush; can be slippery. |
| Post-Rain | Jan – Feb | ★★★★ | Great flow; safer trails; clear skies. |
| Hot/Dry | Mar – June | ★★ | Waterfall may be a trickle; pools dry up. |
| Intermittent | July – Sept | ★★★ | Flow depends on weekly rainfall. |
Pro Tip: Visit in the early morning (before 10:00 AM) to avoid the heat and have the highest chance of having the entire waterfall to yourself.
Practical Tips
- Footwear: Sturdy hiking sandals or sneakers are essential. Do not attempt the upper tiers in flip-flops.
- Insect Repellent: The shaded jungle environment is a haven for mosquitoes. Apply repellent before you start the hike.
- Water: Bring at least 1 liter of water per person. There are no vendors once you leave the parking area.
- Safety: Tell someone where you are going. While the trail is straightforward, it is remote, and phone signal can be spotty at the higher levels.
- Respect Nature: This is a pristine area. Carry out all trash and avoid using soap or shampoo in the natural pools.

FAQ
Is Lardwanorn Waterfall free? Yes, there is no official entrance fee. However, you should bring some small change (20-50 THB) in case a local land owner asks for a small parking fee or if you want to support the maintenance of the trail.
Can you swim at Lardwanorn? Yes, but the pools are generally shallow. They are better for wading and cooling off than for serious swimming. During the rainy season, the pools are deeper and more inviting.
Do I need a guide for this trail? No, a guide is not necessary. The path is relatively intuitive as it follows the riverbed. However, if you are not an experienced hiker, it is always safer to go with a partner.
How does it compare to Na Muang? Na Muang is much larger and more spectacular in terms of height, but it is also very crowded and commercial. Lardwanorn is smaller but offers a much more peaceful, “raw” nature experience.
Is it safe for children? The lower levels are very safe and easy to reach. The upper tiers involve steep climbing and slippery rocks, which may be too challenging for younger children or those without proper footwear.
