Complete Guide to Na Muang Waterfall in Koh Samui

About Na Muang Waterfall

Na Muang Waterfall sits in the forested interior of Koh Samui, a two-tiered cascade that surprises most visitors who've only seen the island's coastline. The lower fall, Na Muang 1, spills over a wide shelf of distinctly purple-violet limestone into a cool, clear pool. The purple tinge comes from iron oxide in the rock, and in certain afternoon light it almost glows. The air here is noticeably cooler and damper than the beach zones, carrying the smell of wet earth and something faintly mossy as you approach through the canopy. Na Muang 2, the upper fall roughly 80 metres high, requires a proper jungle trek to reach. Expect mud, steep patches, and the sound of rushing water pulling you forward through the undergrowth before the falls come into view. The two falls attract very different crowds. Na Muang 1 is accessible enough for families and day-trippers, with vendors selling cold drinks and fresh fruit in the lower car park, the sizzle of grilled corn drifting up the path. Na Muang 2 draws the hikers, rewarding them with more solitude and a taller drop that sends spray across the viewing rocks below. Worth noting: after a dry spell, Na Muang 2 can reduce to a thin thread, while Na Muang 1 holds its flow more reliably year-round thanks to the wider catchment area. For whatever reason, this corner of Koh Samui feels removed from the beach resort atmosphere. You're hemmed in by rubber trees and wild banana palms, and the persistent sound of water makes the whole place feel cooler than it is. The purple rock pool at the lower fall is swimmable and popular with local Thai families on weekends, which is itself a decent indication of quality.

What to See & Do

Na Muang 1, The Purple Pool

The lower fall is the one on every postcard, and for good reason. Water fans out across a broad, gently sloping face of violet-streaked rock before collecting in a wide, waist-deep pool you can wade straight into. The rock underfoot is smooth and slightly slippery. You'll feel the cold water hit your ankles before you're even at the edge. On sunny mornings, shafts of light break through the canopy and the pool takes on an almost turquoise tint against the purple stone.

Na Muang 2, The Tall Upper Fall

The 1.5-kilometre trail to the upper fall is the more physical option. Expect to haul yourself up a rope on one steep section, with the jungle closing in and the footing turning loose and red-clay slippery after rain. The payoff is an 80-metre cascade crashing into a narrow rocky basin, loud enough that you have to raise your voice to be heard. It's the kind of waterfall that generates its own breeze. You'll feel the cool mist on your face well before you round the last bend.

The Forest Trail Between Falls

The connecting path threads through secondary jungle with a soundtrack of cicadas, and if you walk it in the early morning you'll likely have it largely to yourself. Giant fig roots arch across the path in spots, and the light filters green and gold through the canopy overhead. Interestingly, the trail passes through what appears to be old rubber plantation. You can still see the herringbone cuts on some older trees.

The Natural Swimming Area

At Na Muang 1, the pool below the fall is the main event for most visitors. Locals bring their children here on weekends. The shouts and laughter mix with the roar of falling water. The depth varies with season but is typically comfortable for adults to stand in. The current near the base of the fall is lively enough to feel like a natural massage if you wade close enough.

Elephant Trek Starting Point

Adjacent to the Na Muang area sits one of the island's longer-established elephant camps, with trails that wind past both waterfalls. If you arrive early on a weekday morning, you'll often hear the low rumble and the crack of branches before you see the elephants moving through the tree line. It's an unexpectedly affecting sound in the forest context.

Practical Information

Opening Hours

The Na Muang waterfall area is accessible roughly from sunrise to late afternoon. Most visitors arrive between 9am and 3pm. There's no hard gate closure. But the trail to Na Muang 2 is best avoided after dark or during heavy rain when the path becomes treacherous.

Tickets & Pricing

Entry to Na Muang 1 is free. The trail to Na Muang 2 typically involves a modest entry fee collected at a small booth near the trailhead. It's budget-friendly by any measure, and it goes toward trail upkeep.

Best Time to Visit

November through February, when the wet season has recently ended and water flow is at its strongest, is the sweet spot. The falls are lush and full, the air cooler, and the forest trail less brutally humid. March to May the flow drops noticeably at Na Muang 2 during prolonged dry spells. June through October has the most water but also the muddiest trails and occasional trail closures after storms.

Suggested Duration

Allow 45 minutes to an hour for Na Muang 1 alone, or a solid two to three hours if you're doing both falls including the hike. Factor in time to cool off in the pool. Most people linger longer than they planned.

Getting There

Na Muang sits roughly in the center of Koh Samui, off Route 4169, the inland road that cuts south from Nathon toward Ban Hua Thanon. From Chaweng or Lamai, a scooter rental makes the most sense. The ride takes around 20-30 minutes on roads that wind pleasantly through coconut and rubber plantations before the jungle thickens. Songthaews, the shared pickup truck taxis that ply the ring road, don't run this route directly, so from the coast you'd need to take one toward Nathon and arrange a local taxi or motorbike taxi for the final stretch inland. Metered taxis and Grab are available from Samui Airport and the main beach towns. The journey from Chaweng runs mid-range for the island. The car park at Na Muang 1 is large and well-signed; the trailhead for Na Muang 2 starts from the same area.

Things to Do Nearby

Hin Ta and Hin Yai Rocks
The island's most photographed natural curiosity sits on the. Lamai. Two weathered rock formations have taken on unmistakably anatomical shapes. Pair it with a waterfall visit. It's on the coastal road heading back toward Lamai. Jungle interior meets open sea views. Good way to spend a half-day.
Wat Khunaram
A Buddhist temple on Route 4169. Same road you'd take to Na Muang. Houses the preserved, mummified remains of a revered monk seated in meditation. The temple itself is modest. Interior is atmospheric, incense-heavy, quiet. Worth stopping on the way to or from the waterfall.
Samui Elephant Sanctuary
One of several elephant centers in the Na Muang area. Notably operating on an ethical no-riding model. Watch elephants foraging in forested terrain near the waterfall zone. Natural pairing on the same inland excursion.
Lamai Beach
The closest beach to Na Muang. Around 20 minutes by road. Less frenetic than Chaweng. Long curve of pale sand and clear water rewards after a sweaty jungle hike. Southern end near Hin Ta and Hin Yai tends to be quieter than the stretch near the main village.

Tips & Advice

Wear water shoes or old trainers you don't mind getting wet. Purple rock at Na Muang 1 looks grippy but gets slick when wet. Flip-flops are a liability near the base of the fall.
Start the Na Muang 2 hike before 10am if possible. By late morning, tour groups from the beach resorts start arriving. Narrow sections of trail become slow-moving queues.
Bring more water than you think you need for the upper fall hike. Climb is short by trekking standards. Jungle humidity means you'll sweat through a half-litre faster than expected.
The wet season (June, October) delivers dramatic, full-flow waterfalls. Connecting trail between the two falls can become a mudslide after overnight rain. Check conditions that morning before committing to the upper hike.
If the pool at Na Muang 1 is crowded when you arrive, typically 11am to 1pm, spend that time hiking to Na Muang 2. Return when the tour buses have moved on. Pool in the early afternoon on a weekday tends to be noticeably quieter.
