The new boardwalk was completely closed today (I think they were painting the handrails) but we had an amazing boat ride which was well worth the 500 baht. The guide didn't speak English but he frequently cut the engine to point birds out or if we saw one. It was blissfully quiet and we often felt like the only people there. We went at 9am.

The Bueng Bua Nature Center sits within a huge freshwater marsh (one of the largest in Thailand). It is part of the Khao Sam Roi Yot National Park and foreigners will be charged 200 baht (locals 40 baht) to enter. If you paid the fee to visit Phraya Nakhon Cave (located in the same park), one fee covers your visit here as well if you remember to save your entrance ticket. The marsh is adjacent to a striking line of mountains, which makes for fabulous photos looking out over the marsh toward the mountains. A key feature of the center is a long boardwalk out over the marsh. Unfortunately, more than half of the boardwalk is in disrepair (now for more than four years!) and is blocked off. Visitors can still walk part way on the renovated portion of the walk, but will be disappointed that so much is still closed. Especially disappointing that the budget has not be allocated to complete the renovations, considering the steep fees that are charged visitors to enter the park. Visitors can also pay for a boat ride out among the cattails of the marsh. I would rate this place with four or five stars except for the poor maintenance.

Note that there are two ways to reach this place. One is off of highway 4020, which leads you to the ranger station where you can hire a boat. The other is off of highway 4, which leads you to a wooden boardwalk. My review is of the boat trip off of highway 4020. I showed up here around 10AM, hardly anyone around but when I asked if I could hire a boat, someone made a phone call and within a few minutes a boatman arrived. Be aware that not much English is spoken here, but basic communication is still possible. The boat fee is the same no matter how many are in your group - 500 thb. Trip lasted about an hour. Lots of bird life, although it's off in the distance - if you want good bird photos be sure to bring more than just a phone to take photos with. Lotus flowers were sparse, but I knew this before I arrived. The boatman said the flowers come in around December. Be aware, as others have noted, that if you come from Hua Hin, your navigation app will have you turn off highway 4020 onto an unnamed road which turns to dirt in 50 meters. This is not the correct road. Stay on the highway another few kilometers until you reach Samroiyod 6. From here navigation is correct. When you reach the sign for the ranger station at the end of the paved roadway, turn left and drive to the water's edge.

Overrated area, not quite as scenic as the pictures would have you believe, many of the beaches on the other side of this mountain have much more scenic views of the mountains themselves, so may want to skip this area if you're already going to the other (better) areas nearby. The pictures make it feel like you'll be out in nature, but in reality, the main road is right nearby and the entrance gate that collects the 200 baht admission from foreigners is within view. You aren't hiking into some remote area here, so it feels more like a tourist attraction and less like nature. They obviously have not taken care of this area because the boardwalk was mostly closed when I went this week, Only half of it was open, which was quite disappointing as well. It's also very convenient for the boat captains there as the only way to go out on the lake and see things while it's closed is by paying for one of the boats to take you out there instead, since you can't walk out there while it's closed. There's nothing else to do at this location other than see the boardwalk. They shouldn't be charging 200 baht to see a closed boardwalk, and they should have taken better care of it all these years so they wouldn't need to shut down the entire thing to make repairs.

Visited after Phraya Nakhon cave and Khao Deng View Point on the same day. Had refreshments and re-applied sun block at the restaurant before heading to the education centre to take a look. It was relatively sparse and had to remove our shoes before entering. As the boardwalk was still under construction, we decided to do the boat ride immediately. It costs 500tbh for a boat (1hr ride) which could take up to 4 pax. The fee was paid to the officials there instead of the boat captain. Even though the lotus were not in full bloom (season probably ending), we saw a lot on the boat ride. There were different species of birds and insects. The mountain formations were also spectacular. We really enjoyed the privacy of the boat ride and the peace and quiet while seeing nature at work. Would highly recommend this activity to everyone visiting Hua Hin.

We visited this marsh after climbing the Khao Daeng view point (elsewhere in the national park) and found it to be a great, peaceful and picturesque corner to wile away a few hours. The scenery is beautiful, lush and very unique in Thailand. The site also benefits from not being overrun by lots of tourists. We went late July, during low-season, and were the only ones there on a bright sunny afternoon! Although it is not possible to complete a full route, as the boardwalk is undergoing repairs, you can still walk a considerable way and enjoys views across the marsh.

Admission ticket is 200THB per person. The ticket is valid for 1 day and can be used to enter multiple sites of the national park. This place is beautiful and is a nice place to spend an hour or so. So start early so you have time to visit other placed. You are not able to walk the whole board walk due to disrepair. But is it still a very nice visit.

The lotus season is over. Only a few lotus blooming. Some part of the board walk are still not upgraded yet. Still ok to walk but be careful. 200bath per pax for foreigners. totally worth it if lotus are blooming but not for now. So do check if lotus are in season before venturing there. It’s almost an hour drive from Hua Hin City.

Went to the ranger station to get a boat ride for 500 Baht for max 4 pax per boat. Went in late Dec and lotus were already in bloom. Boat ride goes on for an hour. Perfect to enjoy the scenery and watch the different types of birds at the wetlands.

I'm retired and live locally in Pran Buri - DONT GO - DON'T VISIT IT - it's very dangerous the walkways are rotting and if they keep any of it open you may have a serious fall. It would be beautiful, magical, but due to lack of love and DESPITE CHARGING MORE FOR FOREIGNERS - the money is not going into it. I read they are rebuilding it, ho ho who died? Wait until you get positive reviews. I cannot understand the mentality behind attractions like this in Thailand, the "cafe" was appalling too, cold coke or cold coke with cold coke, they dont seem to realise that cooking a few simple foods and offering Tea (in teapots) and Coffee would improve their profile and attract more "farang" people. They just think that foreign tourist are just some kind of unintelligent "animal" that doesn't need feeding will look around spend loads of money then go home happy - well it isn't true the standards of all Thai visitor places around sam roi yod need to be brought up to the modern world level. Thailand has serious travel problems and this is ONE OF THEM..
