As the visitor approached Tan Rua Waterfall, they felt a sense of discovery, as if they were uncovering a secret tucked away in the lush jungle of Koh Samui. Located in the Mae Nam area of Thailand’s second-largest island, Tan Rua Waterfall, also known as Secret Falls, is a charming cascade that offers a peaceful escape from the island’s bustling beaches. For someone who has explored many of Thailand’s natural attractions, Tan Rua stands out for its secluded beauty, accessible trails, and the thrill of reaching a less-touristed spot. In this review, the visitor’s experience of Tan Rua Waterfall is detailed, covering its scenic allure, activities, unique atmosphere, and practical tips for a memorable visit.
Getting There: A Journey Through the Jungle
The visitor’s journey to Tan Rua Waterfall began in Mae Nam, a quieter area of Koh Samui known for its laid-back vibe. The waterfall is located off Maenam Soi 5, accessible by a winding road that leads into the island’s mountainous interior. The visitor chose to rent a scooter, a common mode of transport on Koh Samui, costing around 200 baht ($6 USD) per day. The drive took about 15 minutes from Mae Nam Beach, following a paved road that grew steeper and narrower as it approached the waterfall. For those less comfortable with scooters, cars or taxis are viable options, though the visitor noted that the final stretch of road is steep and may require parking and walking the last few hundred meters.
The road to Tan Rua was an adventure in itself, passing through lush jungle and offering glimpses of the Gulf of Thailand from elevated points. The visitor followed coordinates (9.569465, 99.995353) to a turnoff from the main road, eventually reaching a dead-end near the waterfall’s entrance (9.544506, 99.991538). A small parking area marked the start of the trail, and the visitor was greeted by the sound of distant water and the scent of damp earth. Entry to Tan Rua Waterfall is free, though a donation box supports maintenance, and the visitor tossed in a few baht as a gesture of appreciation.
The Waterfall: A Picturesque Retreat
Tan Rua Waterfall is a classic jungle cascade, spilling down through a rocky, vine-draped ravine into a natural pool below. The visitor was struck by its serene beauty, with water flowing over smooth boulders and surrounded by tall trees and tangled foliage. While not the largest waterfall on Koh Samui—Na Muang and Hin Lad are bigger—Tan Rua’s charm lies in its intimate setting and relative seclusion. The visitor noted a decent flow of water, even during the shoulder season, though reviews suggest the falls can dwindle in the dry months of July and August.
The waterfall’s setting is enhanced by its jungle surroundings. The visitor marveled at the towering trees and vines that frame the cascade, creating a canopy that filters sunlight into a soft, green glow. A rope suspension bridge, part of the nearby Tree Bridge Cafe and zipline attraction, added a whimsical touch, swaying gently as the visitor crossed it to reach the waterfall’s base. The pool at the foot of the falls was clear but contained some branches and leaves, so the visitor proceeded cautiously when wading in. Nearby rocks offered perfect spots for photos, though the visitor heeded warnings about slippery surfaces and avoided climbing too high.
The trail to the waterfall included a short climb over uneven stone steps, passing the Mae Nam Viewpoint, which offered sweeping views of the island’s northern coast and the Gulf of Thailand. The visitor paused to take in the vista, appreciating the contrast between the jungle’s greenery and the distant turquoise sea. The entire hike from the parking area to the waterfall took about 15-20 minutes, making it accessible for most fitness levels, though the visitor noted that the steep, rocky path required careful footing.
Activities: Nature and Adventure
Tan Rua Waterfall offers a mix of relaxation and light adventure. The visitor spent time wading in the natural pool, enjoying the cool water after the warm hike. The pool is suitable for a quick dip, though they avoided swimming due to the debris mentioned in reviews. For those seeking a more immersive experience, the visitor observed that the pool could be refreshing in the wet season (October to December) when the water flow is stronger.
The visitor was intrigued by the nearby Canopy Adventures zipline, which passes over the waterfall area. They heard the excited shouts of zipliners soaring above the treetops, adding a lively energy to the otherwise tranquil setting. While they didn’t try the zipline themselves, they noted its popularity and the stunning views it must offer of Tan Rua from above. Photography was another draw, with the visitor capturing the waterfall’s cascade, the suspension bridge, and the lush jungle backdrop.
Relaxation came naturally at Tan Rua. The visitor found a flat rock near the pool and sat for a while, listening to the water and the rustle of leaves. The absence of crowds made it easy to unwind, and they appreciated the lack of commercial stalls, which preserved the waterfall’s natural charm.
The Atmosphere: Serene and Secluded
Tan Rua Waterfall exudes a peaceful, almost hidden vibe, earning its nickname “Secret Falls.” The visitor noted the quiet hum of the jungle, punctuated by the sound of water and occasional zipline shouts. Unlike Koh Samui’s busier attractions, Tan Rua felt like a true escape, with only a few other hikers and locals sharing the space. The visitor overheard a Thai couple discussing the waterfall’s beauty compared to more crowded spots like Na Muang, agreeing that Tan Rua’s seclusion was its greatest asset.
The crowd was small, consisting of adventurous travelers, local families, and a few zipline participants. The visitor appreciated the diversity and the shared sense of discovery among those exploring the trails. The nearby Tree Bridge Cafe, with its observation deck, offered a cozy spot to relax, and the visitor imagined sipping coffee there while taking in the jungle views.
Food and Drinks: Simple and Nearby
Tan Rua Waterfall has no on-site food vendors, preserving its unspoiled feel. The visitor brought a water bottle and some snacks from Mae Nam, which sufficed for the short visit. The Tree Bridge Cafe, located near the suspension bridge, offers coffee, cold drinks, and light snacks, and the visitor purchased a chilled coconut water for 50 baht ($1.50 USD), enjoying it while admiring the scenery.
For a proper meal, the visitor returned to Mae Nam Beach, where they dined at a beachfront restaurant serving khao soi, a creamy coconut noodle dish, for about 120 baht ($3.50 USD). The vibrant flavors and ocean views were a perfect complement to the day’s jungle adventure. Those planning a longer visit should pack a picnic to enjoy by the waterfall, as the setting is ideal for a relaxed meal.
Quirks and Tips
Tan Rua Waterfall is a delight, but a few quirks are worth noting. The final road to the parking area is steep, and the visitor advises parking at the last intersection and walking if driving a car, as the incline can be challenging. Scooters handle the road better but require caution. The trails can be slippery, especially after rain, so sturdy shoes are essential. The visitor also recommends insect repellent, as the jungle attracts mosquitoes.
Visiting early in the morning, as the visitor did, ensures cooler temperatures and fewer people. The waterfall is open year-round, 24/7, but the flow is best during the wet season. The visitor suggests avoiding the dry season (July-August) when the falls may be reduced to a trickle. Respecting the environment is crucial—pack out all trash, and avoid climbing the rocks, as slips can cause injuries.
Why Tan Rua Waterfall Stands Out
Tan Rua Waterfall is a hidden treasure that offers a quieter alternative to Koh Samui’s more famous cascades. Its jungle setting, accessible trails, and serene pool create an intimate experience that feels like a discovery. Compared to Na Muang or Hin Lad, Tan Rua’s seclusion and natural charm make it a standout for those seeking an off-the-beaten-path adventure.
As the visitor left, the jungle’s green canopy and the distant sound of water lingered in their memory. Tan Rua isn’t just a waterfall—it’s a peaceful retreat that captures the wild, untamed spirit of Koh Samui.
Final Thoughts
The visitor’s time at Tan Rua Waterfall was a highlight of their Koh Samui journey. Whether wading in its cool pool, hiking its jungle trails, or simply soaking in the serenity, the waterfall offered a perfect blend of adventure and calm. For anyone visiting Koh Samui, Tan Rua Waterfall is a must-see—a secret worth uncovering in the island’s lush interior.
