Bueng Kan Nature Trip
Phu Wua–Chet Si Falls–Bueng Khong Long

Bueng Kan is still one of Thailand's quietest, most untouched provinces. If you want to get away from the crowds and spend a few days with forest, waterfalls, and a wide-open lake, the Phu Wua–Chet Si Falls–Bueng Khong Long route is the loop we've put together for you. This is a relaxed 3-day, 2-night plan you can drive yourself without rushing, timed so you catch the waterfalls when the water is strong and the lake when the light is best.

Bueng Kan Nature Trip Phu Wua–Chet Si Falls–Bueng Khong Long

🔄 Updated 21 Jun 2026

Before we start, we'll be honest: this route works best in the rainy season through early cool season (roughly July–November), because Chet Si and Tham Phra waterfalls sit inside the Phu Wua Wildlife Sanctuary and only really shine when the water is high. In the dry season (March–May) the falls can dry up until there's almost nothing left to see. Bueng Khong Long, on the other hand, holds water all year and is good in any season — so if you come during the dry months, you can shift the plan to focus on the lake and the Mekong views instead.

The main way to get around is to drive yourself, since the sights are spread across several districts (Mueang Bueng Kan–Seka–Bueng Khong Long) and public transport barely reaches them. If you don't have a car, renting one or hiring a car with a driver by the day will make things much smoother.

The 3-day plan at a glance

  • Day 1 — Arrive in Mueang Bueng Kan, warm up along the Mekong, see Wat Aham Sila Wat, and overnight in town.
  • Day 2 — Head into the Phu Wua area for a full day at Chet Si and Tham Phra waterfalls, then sleep over on the Bueng Khong Long side.
  • Day 3 — A quiet morning at Bueng Khong Long for birdwatching and lake views, then make your way back.

Plan your accommodation smartly

Sleeping in Mueang Bueng Kan on the first night is the most convenient, since restaurants and convenience stores are all close by. For the second night, move over to the Seka–Bueng Khong Long side so you don't have to backtrack so far.

Day 2 — Phu Wua area, Chet Si and Tham Phra waterfalls

Today is the highlight of the trip. Both waterfalls sit inside the Phu Wua Wildlife Sanctuary in Seka district. Leave a little early so you can enjoy the water before the crowds. Bring grippy shoes, a change of clothes, and some food, because the shops inside are limited.

Day 2

Chet Si Waterfall + Tham Phra Waterfall

07:30
Leave Mueang Bueng Kan and head for Seka district, about an hour and a half awayStop for breakfast or pick up supplies for the car before you head out of town.
09:30
Reach Chet Si Waterfall (Ka-am Waterfall). Entry 60 THB, open 08:00–16:00The waterfall has several tiers, and the mist catching the sunlight creates rainbow colors — that's how it got the name Chet Si ('seven colors'). You can swim in the lower pool.
11:30
Break for lunch near the waterfall, where there are restaurants and a parking areaFood at this spot is priced for tourists, so set your expectations a little on price.

17:00

19:00
A simple dinner near your accommodation, then rest up for an early start for birdwatchingRestaurants around here close early, so if you tend to get hungry late, keep some snacks on hand.

What to know about the waterfalls

The waterfalls in the Phu Wua area are seasonal. In the rainy season the water is strong and beautiful but the rocks are slippery and the current is fast — watch the warning signs and don't go into spots the staff have closed off. In the dry season the water can drop so low that swimming isn't possible. Check the water conditions with the province's or sanctuary's page before you set out to be sure.

Day 3 — Bueng Khong Long, a quiet lakeside morning

Bueng Khong Long is a large freshwater lake registered as an important wetland, and it holds water all year. In the cool season (roughly November–February) lots of migratory waterbirds arrive — ducks and egrets among them — so if you come during that window, getting up early to watch the birds is well worth it.

Day 3

Bueng Khong Long Park + the journey home

06:30
Get up early and head to Bueng Khong Long Park for the cool air and morning lightThere's a bird-watching tower and a viewing deck. Early on the water is still and mirrors the sky.
07:30
Walk around the park and watch the waterbirds — in the cool season you'll see flocks of migratory birdsBring a camera or binoculars if you're serious about birdwatching.
08:30
Find breakfast around the Bueng Khong Long market and try some khao piak or other local morning bitesIt's a small morning market, but there's local food to try.
10:00
Get a few more lake photos in the late morning, then check outIf you have time to spare, you can stop by Tham Naga (Naga Cave), which isn't far from Bueng Khong Long.
11:00
Set off for the journey back, heading to Udon Thani or Nong Khai to connect onwardAllow extra travel time, since distances in Isan are fairly long.

Rough budget per person

  • 2 nights' accommodation — around 800–2,400 THB (homestay to resort, cheaper split between people)
  • Waterfall entry — Chet Si 60 THB + Tham Phra/boat fee as charged, a few hundred THB in total
  • Food — around 600–1,000 THB/person for 3 days, eating local
  • Fuel/car rental — depends on where you're coming from; budget extra fuel for driving across several districts

What to pack for the forest

  • Grippy or water shoes — the rock terraces at the waterfalls are very slippery
  • A change of clothes and a waterproof pouch for your phone, since you'll definitely get in the water
  • Drinking water and snacks in the car — shops in the forest area are limited
  • Insect repellent and sunscreen — you'll be out in the forest and sun all day
  • Cash on hand — some spots take cash only, and mobile signal drops out in places

FAQ

When is the best time to visit Chet Si and Tham Phra waterfalls?

The rainy season through early cool season, roughly July to November, because both waterfalls sit in the Phu Wua area and look their best when the water is high. In the dry season, roughly March to May, the water is often low or gone. Check the water conditions with the province's page or the Phu Wua Wildlife Sanctuary before you go.

How much is entry to Chet Si Waterfall, and what are the hours?

Entry is 60 THB per person, open from 08:00 to 16:00. There's a parking area, toilets, and restaurants near the waterfall. It's best to go in the morning so you can enjoy the water before the crowds and head out before closing.

Can I do this route without my own car?

It's fairly difficult, since the sights are spread across several districts and public transport barely reaches them. We'd recommend renting a car or hiring one with a driver by the day, which is far more flexible and saves a lot of time.

Can you visit Bueng Khong Long all year round?

Yes, because Bueng Khong Long is a lake that holds water year-round. It's especially lovely in the cool season, roughly November to February, when large numbers of migratory waterbirds arrive. Getting up early to watch the birds and see the lake in the morning light is the most rewarding way to enjoy it.

Can this plan include Tham Naga (Naga Cave)?

Yes. Tham Naga is also within Bueng Khong Long district, but you have to register and book a slot in advance, and there's a fair bit of walking uphill. If you want to add it to this trip, allow extra time on Day 3 or extend to 4 days so you're not too rushed.
