Bueng Chawak Chaloem Phra Kiat sits in Doembang Nangbuat district, north of Suphan Buri town and about 170 km from Bangkok. The lake itself is a natural crescent-shaped body of freshwater spanning thousands of rai, stretching across into Hankha district in Chai Nat province. The land around it has been developed into a learning and recreation area with several zones to walk through, and the busiest spots are the aquarium and the zoo.
The nice thing here is you can spend the whole day without moving on. Kids get to see fish, animals, and crocodiles; adults get to wander along the lake and catch the breeze; and the entry price isn't steep. That's why it's such a popular stop for families driving through Suphan Buri.
Entry fees and opening hours
Fees are split by building and zone. If you want to see everything from the aquarium to the crocodile pond, the combined price is still very good value for what you get to see.
- Aquarium Building 1 + Building 2 + crocodile pond — adults 30 THB, children 10 THB (Building 2 has the freshwater fish tunnel)
- Building 3 “Paradise of the Undersea World” — saltwater fish and coral zone, adults 150 THB, children 50 THB (charged separately from the first two buildings)
- Zoo and giant aviary zone — some areas are free to enter, and certain periods are free admission for festivals; it's worth checking the official page before you go
The aquarium section is open roughly 10:00–17:00 on Monday–Friday and around 09:00–18:00 on Saturday–Sunday. Long weekends get busier than usual, so if you want an easy walk, a weekday or early morning is quieter.
Quick check before you go
Entry fees and free-admission periods for each zone change with festivals and the agency's policy. It's best to check the official Bueng Chawak page or the Suphan Buri provincial page before you set off, so you can budget and time things right.

The aquarium — river fish, the fish tunnel, and the undersea world
The heart of Bueng Chawak is the aquarium, split across several buildings. The highlight everyone talks about is the freshwater fish tunnel in Building 2 — a glass tunnel you walk through underwater, watching big river fish glide over your head, including Mekong giant catfish, giant barb, Siamese tigerfish, and plenty of other Thai river species.
Building 3, named “Paradise of the Undersea World,” is the saltwater and coral zone, with brightly colored marine tanks, sharks, clownfish, and other sea creatures. It's charged separately and costs more than the freshwater zone, but kids usually love it because they get to see sea fish up close without having to reach the actual coast.
Shooting photos in the tunnel
The tunnel is fairly dim and the fish never stop moving. For sharper shots, turn off your flash (it reflects off the glass) and shoot when the fish are swimming slowly — you'll get a clearer image.
The zoo and giant aviary
Next to the aquarium is an open zoo with a range of animals for the kids to see, and it's an easy walk around. The standout is the giant aviary — around 5 rai in size and roughly 25 m tall — that you can walk right into, with dozens of bird species flying all around you. Kids love it because they see birds up close rather than crammed into small cages.
Giant aviary
A large walk-in aviary where dozens of bird species fly around you. A photo spot and the kids' favorite.
Freshwater crocodile pond
Thai crocodiles in a near-natural, spacious setting with safe viewing points, where you can watch them bask in the sun up close.
Open zoo
Walk among a range of animals in a shady area — good for taking small children for a stroll in the morning or evening.
Strolling along the lake and rest spots
Beyond the animal zones, the area around the lake is a good place to wander and catch the breeze, with open lawns, shade trees, and waterside seating. The evening breeze is pleasant, and many families lay out a mat to rest after walking the animal zones. There are restaurants and snacks on site, so no worries about going hungry along the way.
- Lakeside lawn — seating to rest and catch the breeze, with wide water views to photograph, ideal in the evening before you head home
- On-site restaurants — rice dishes, noodles, and snacks to refuel mid-walk
- Native vegetable garden — a learning zone of local plants and vegetables, a pleasant wander for anyone who likes nature
Planning a full day at Bueng Chawak
Bueng Chawak can fill a whole day, and with a good order to your route you'll cover every zone without wearing yourselves out. Here's a smooth walking plan for families.

Getting there and tips
The easiest way is to drive yourself. From Bangkok it takes around 2.5 to 3 hours along the Suphan Buri–Chai Nat route, and there's plenty of parking on site. Without your own car, public transport is fairly awkward since it's outside the town, so renting a car or going with a family tour is the way to go.
- Wear comfortable shoes — it's a big site and you'll walk all day, so sneakers help a lot
- Bring an umbrella/hat and water — some zones are outdoors and the midday sun is strong
- Come on a weekday if you don't like crowds — weekends and long weekends are much busier
- Allow a full day — to see every zone, come in the morning and make a long day of it through to the evening
