First thing to understand: Pha Chana Dai is not a drive-up-and-photograph-it spot. The viewpoint itself sits deep in the Dong Na Tham forest, and ordinary cars can't get up there. You park at the Dong Na Tham checkpoint and switch to a local vehicle (a pickup or one of the park's tour trucks) to go the rest of the way, on fixed up-and-down shuttle times. For sunrise, the sensible move is to spend a night on the cliff, because the morning run leaves as early as 4:30 a.m. and by the time you reach the viewpoint the sky is just starting to lighten.
What and where is Pha Chana Dai, and why go
Pha Chana Dai is a sandstone cliff on the bank of the Mekong, in the Dong Na Tham forest of Pha Taem National Park, in Na Pho Klang sub-district, Khong Chiam. What makes it special is that it's the coordinate where you see the sun come up before anywhere else in Thailand, looking across the Mekong to the mountains on the Lao PDR side. In the late-rains, early-cool window you've got a chance at a sea of mist drifting over the river. There's a natural stand of two-needle pines on the cliff and a camping ground for an overnight stay. The site used to open in stretches and then close again; it only came back fully on 1 June 2025, so it's still a corner most people haven't gotten around to.
- Park entrance fee — Thai adults 40 THB, children 20 THB · foreign adults 400 THB, children 200 THB
- Camping fee — 30 THB per person · no tent of your own? The park rents them for around 225 THB each (with a sleeping mat and pillow)
- Getting up the cliff — cars can't make it; park at the Dong Na Tham checkpoint and switch to a local vehicle, on fixed up-and-down shuttle times
- Viewpoint vs. camping ground — about 800 m apart and walkable; it's a short morning walk out to catch the light
- Facilities — separate men's and women's toilets, but no electricity, so bring a flashlight/power bank and your own food. Mobile signal is True and AIS
Pha Chana Dai up-and-down shuttle times
There are 3 runs up from the Dong Na Tham checkpoint — morning 04:30–06:30 · midday 10:30–13:00 · evening 16:00–18:00. The runs down are 07:30–09:30 · 14:00–15:00 · 19:00–19:30. If you want sunrise without camping, take the evening run up to sleep over and walk out to the viewpoint before dawn. Always check the latest times with the park before you go, as they shift with the season. Call 045-252-541.
Book the activities in your Ubon Ratchathani trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
Day 1 — into Khong Chiam, take in Pha Taem, then up to sleep on the cliff
Ubon city to Khong Chiam is about 80 km, an hour and a half of driving. On day one we knock out the lower sights first — Pha Taem and Sao Chaliang, which sit right by the access road and are easy to get to. Then in the afternoon we head to the Dong Na Tham checkpoint to catch the evening shuttle up Pha Chana Dai, arriving in time to pitch the tent before dark and catch sunset from the cliff too.

Want first light without an overnight stay
If you really don't want to camp, you can take the 04:30 morning run from the Dong Na Tham checkpoint — but that means getting up in the middle of the night from your lodging in Khong Chiam and driving over in time to make the shuttle, which puts a lot of pressure on the clock. We think one night in a tent on the cliff is the easier call and gets you far more of the atmosphere.
Day 2 — Thailand's first light, then down for the two-colour river
This morning is the highlight of the trip. Up before 5 a.m., walk to the cliff-edge viewpoint and wait for first light to slowly push the horizon up on the Lao side. If you're lucky in the late-rains, early-cool season, there'll be a sea of mist drifting over the Mekong too. Once you've got your fill of photos, take the morning run down and come back to take in the two-colour river and a bite to eat in Khong Chiam before driving home.

Which season to go, and when it's closed
Pha Chana Dai only opens in the cool and hot seasons; it closes in the rainy season because the way into the Dong Na Tham forest gets slippery and dangerous. The most popular window is the late-rains, early-cool season through winter, roughly November to February — cool, comfortable weather, clear skies, and a real shot at a sea of mist over the Mekong in the morning. The hot season still works, but the days get scorching and the mist thins out. Every time before you go, check with the Pha Taem National Park page that it's open and what the shuttle times are, since they adjust with the weather.
Getting there and what to pack
- Your own vehicle is easiest — Ubon city to the Dong Na Tham checkpoint is about 100 km, and public transport barely reaches it. If you fly into Ubon airport and rent a car to drive yourself, that's the smoothest option.
- Up the cliff means switching to a local vehicle — cars can't make it; park at the Dong Na Tham checkpoint and switch to a park/tour vehicle, on fixed up-and-down shuttle times, with the fare worked out on the spot by number of people.
- Tent and bedding — the park rents them, but during busy periods they may run out, so bringing your own tent is the safer bet. The camping fee is 30 THB per person.
- Flashlight, power bank, warm layer — there's no electricity on the cliff, and the wind is strong and cold at night, so even in the hot season you'll want a windbreaker.
- Food and water for every meal — there are no shops on the cliff, so pack enough dinner, breakfast, water and snacks, and carry every piece of trash back down.
- Sneakers — Pha Taem, Sao Chaliang and the paths on Pha Chana Dai are all stone and steps, and sandals slip easily.
What to eat before heading up and on the way down
Since you eat what you pack up on the cliff, the proper meals land in Khong Chiam both before you go up and on the way down. The standout here is fresh Mekong fish — giant catfish, Teepho catfish and river prawns — done as tom yum, grilled whole, or as larb, eaten with sticky rice and jaew dipping sauce. For the café crowd, there are river-view spots to rest up and shake off the tiredness.
Riverside restaurant, Khong Chiam
A local eatery on the riverbank, leaning on Mekong fish and river prawns, with a water's-edge setting. Good for a filling lunch before heading up the cliff.
Mong Khong Cafe & Camping
A café right on the Mekong with drinks, desserts, Thai–Isan–Western food and a camping zone. Drinks from around 60 THB, with a panoramic river view.
Khwam Song Jam Cafe
A chilled-out riverside café with house-roasted coffee, well-priced cakes and a savoury menu. You can sit and watch the river for ages — a good last cup before heading home.
The honest bit
Pha Chana Dai really is beautiful, but it really is rough too. You have to camp, there's no electricity, you carry your own gear up, and if the sky clouds over you might not get the first light you were hoping for. If your family has small kids or older relatives who struggle to walk, weigh it up first. Anyone who's fine with camping will find it well worth it — but if you'd rather take it easy, you might choose to watch the sunrise from the Pha Taem viewpoint instead, which you can drive right up to and is easier to reach.
