Thee Lor Su Riverside — Timber Bungalows on the Mae Klong River, a Basecamp for the Thi Lo Su Waterfall
If you've set your sights on the Thi Lo Su waterfall — the one many Thais rank as the country's largest and most beautiful — the first question isn't how to get there, it's where to sleep the night before the climb. Thee Lor Su Riverside Resort is the name most people who've been to Umphang mention first. It's a cluster of teak bungalows spread along the bank of the Mae Klong River, some raised on stilts directly over the water. Be clear from the start: this is not a polished resort, and the rooms are plain village-style timber houses. What guests come back talking about is waking to the sound of the river outside the bungalow — and having a 4WD vehicle and a guide on hand to take them up to the falls the next morning.
Thee Lor Su Riverside sits in Mae Klong sub-district, Umphang — the far western corner of Tak province on the Myanmar border. The resort is a scatter of teak bungalows across a plot on the bank of the Mae Klong River. They range from small fan-cooled units to air-conditioned houses, and a few sleep 5–7 people for groups or whole families. Each bungalow has its own name (Rimnam 1–4, Leelawadee, Rachawadee) and comes with an en-suite bathroom, hot-water shower, a TV, and local woven textiles over the beds. Plain but clean, it feels closer to staying at a relative's house in the forest than at a hotel.
The strongest card here is the setting right on the Mae Klong River. The riverside bungalows are raised high on stilts, jutting out over the water with a balcony where you can sit and watch the river run over the rocks below. Several guests say the best moment is early morning before you set out — mist still hanging over the water, the air cool, the sound of the river and a few birds the only thing you hear. Worth knowing: not every bungalow sits on the water. Some are set further back in the garden, so if you want a genuine riverfront unit you'll need to ask for one when you book.
People who have made the journey to Umphang tell remarkably similar stories, and what they return to most often has nothing to do with the room or the amenities. It is the hour before dawn, when you open the bungalow door and step onto the balcony to find the Mae Klong River completely swallowed by white mist, the air cold enough to see your breath, the only sounds the water running over the boulders below and a few unseen birds calling from the forest. You stand there with a hot coffee, knowing that in a few hours you will be sitting in a rubber boat as it pitches through the rapids, watching limestone walls rise on either side, and that by late morning you will be standing in front of the largest waterfall most people in Thailand have ever seen. Several guests describe the Umphang trip as the most physically demanding journey they have taken — the 1,219 curves of Route 1090, the nausea on the bends, the pre-dawn starts — but when asked whether they would go back, the answer is almost always yes, and usually without hesitation. Part of that is the falls themselves. The Thi Lo Su waterfall drops in multiple tiers across a broad face of rock, and the scale of it tends to catch people off guard even when they have studied photographs and read every account written about it. Standing in front of it is genuinely different from reading about it, and a surprising number of guests say it is the single most impressive natural sight they have encountered anywhere in the country. Part of the pull is also the setting on the Mae Klong River that is genuinely hard to replicate anywhere else in Thailand — the combination of the forested banks, the river bends, the silence broken only by water and wildlife, and the knowledge that you are a long way from anything that looks like ordinary life. And part of it — something that comes up again and again in what guests write afterwards — is the team at the resort, who keep every stage of the trip running smoothly from the moment you arrive to the moment you leave. Guests single out specific staff members by name in their accounts, which is not something that happens often enough to be unremarkable. A place is easier to reach by better roads and with fancier fittings, but that particular texture — the people, the river, the mist, the sense that the trip demands something from you and gives something real back — is harder to manufacture. The bungalow itself is simple timber and a ceiling fan or a window unit, and that is exactly the right frame for this kind of trip. You are not here for a room. You are here for the river at dawn and the falls by mid-morning, and Thee Lor Su Riverside delivers both, which is why people keep coming back and keep telling others to go. What stays with you from a place like this is not a thread count or a minibar. It is that particular morning, the mist over the river, the coffee going cold in your hands, and the knowledge that you are about to see something most people only ever look at in photographs.
What sets Thee Lor Su Riverside apart from an ordinary place to sleep is that it works as a full tour basecamp, not just a bed. The resort runs 2-day/1-night and 3-day/2-night packages that fold in accommodation, meals, rubber-boat rafting on the Mae Klong River, a four-wheel-drive transfer up to the Thi Lo Su waterfall, and travel insurance. The rafting route passes Pha Bong, Pha Phueng, the Thee Lor Jor (Rainbow) waterfall and the hot springs before reaching the falls themselves. If you have extra days, there's also a trekking package out to Pi Tu Gro, the heart-shaped waterfall that takes a longer walk to reach.
Food is a point reviews return to often. Dinner is several freshly cooked Thai dishes served family-style — the kind of home cooking that travellers come back to after a long day and call better than they expected. The staff are the other thing people single out: reviews name team members like Khun Mee and Khun Not for looking after guests and keeping trips running smoothly. Honestly, half the appeal of this place comes from the people who run it, not the bungalows themselves.
Now the part to know before booking — this place is genuinely remote and rough to reach. Umphang is about 164 km from Mae Sot, but the drive runs along Route 1090, famous for its 1,219 curves; it takes roughly 3–4 hours and anyone prone to motion sickness should come prepared. Rooms are basic timber-house standard, and there's no daily housekeeping like a city hotel. Some reviewers note the bathroom could be cleaner, and the current in front of the resort can run strong enough that swimming isn't possible. Bring your own basics — soap, toothpaste and mosquito repellent are worth packing.
On price — bungalows start around ฿900–1,200 per night for the room alone. But most people who come to Umphang choose a tour package instead, since it bundles the 4WD, guide, meals and rafting into one rate: a 2-day/1-night package starts around ฿2,500–4,500 per person (the more people, the cheaper per head), and a 3-day/2-night around ฿3,200–5,300 per person. The Umphang Wildlife Sanctuary entry fee (about ฿200) is not included. Umphang's high season is late rains into early winter (November–January), when the falls run full and the mornings are misty — rooms book out fast, so reserve several weeks ahead.
The bottom line: Thee Lor Su Riverside works best for people who are coming specifically for the Thi Lo Su waterfall and Umphang's wild country and want a riverside base that arranges the whole tour in one place, with no scramble to find a vehicle or guide. If you want a crisp air-conditioned room, full amenities or an easy drive, this probably isn't your answer. But if you can take the plain bungalows and the winding road in exchange for standing in front of one of the country's finest waterfalls — a small bungalow on the river here is the right base for that kind of trip.
