The trip was well... - The trip was well organized and after some delay (due to other travelers not showing up) we went straight to the national park. Our guide was very enthusiastic and knew exactly where to look to see interesting or well hidden animals. In our case we saw monkeys, a lot of lizards, a baby Komodo and even an elephant (obviously nothing is guaranteed, but we had a lot of luck it seems). After the final hike we emerged at a small restaurant with prices in the 50~150 THB range. Our only suggestion for improvement would be to start the tour way earlier (around 6 am) so you have more time in the park. At the end, we had to rush to the bus to get back to bangkok on time.

Perfect trip - Golf is a very nice guide, speaking fluently in English with extremely big knowledge about the jungle/forest, plants and animals living there. I can highly recommend!

Jungle excursion - Enormous park with truly evocative beauties and a wealth of impressive flora and fauna. The guides really go out of their way to allow you to meet any animal and to pass on knowledge about the park. It's absolutely worth it!

Good hike through a national park. - The tour was a good opportunity to see this far flung national park, if you are like me and do not want to attempt driving in Thailand (I am not familiar with their road suggestions/etiquette and my spatial awareness is not advanced enough to tetris a car through traffic). Our guide was very enthusiastic and affable. This is a good tour for ablebodied people who like to hike and attempt nature watching. First things to note is that this is a national park, not a game reserve with trackers or a zoo. Animals are wild so there is no guarantee you will see them. Unfortunately we were not luck to see elephants when we went, they showed themselves 30 mins after we left, as our guide's friend confirmed. The trails are not accessible by any means. They are marked but not paved and there are sections of steep stair or tree roots/rocks to discend. We went during a particularly dry warm season but it is a tropical forest so it is an all weather activity. Prepare accordingly. Only 2 of 6 brought an umbrella which helped with not getting completely soaked. Guide was used to the rain but as he said, you will have to be 200% careful. In some sections 500% careful or you could fall (sometimes into elephant poop). All of us slipped at least once but only 1 badly. If you have camera gear, have a waterproof bag. Recommend long sturdy pants unless you are ok with some scratches from thorned plants and some potential ant bites. Pants count: 2 cotton pants split at seams, 1 shorts a bit muddy from sitting to navigate downwards, 1 yoga mants with tear in the leg from spiky plant. Spotted : monkeys, deer, scorpion, monitor and lots of butterflies.

Nice excursion with experienced guide - It was a really nice trip out in nature. The trip by car was comfortable. Surina was a very good guide, she knows the park very well and shared with us as much as she could. She and Frank took good care of us during the whole trip. We were not lucky to see any elephants but saw many monkeys, an iguana, etc. The two waterfalls didn't have a lot of water since it was dry season but still really cool to see.

Wonderful tour with Surina and Frank - My friend and I went to Khao Yai National Park today with our guide Surina and driver Frank and we had a wonderful day. Surina is a very nice, open-minded and committed person who gave us a really great day. We can definitely recommend this tour, we had a lot of fun and learned and experienced a lot.

A lovely day trip to get away from the smog of Bangkok, best to go in (or end of) wet season to see the waterfalls - This was a lovely day trip, although as it is the dry season, the waterfalls weren’t flowing at the national park. We saw some interesting bird species and a crocodile too. Surina was a lovely and knowledgable tour guide and was vigilant and made sure we are safe walking through the jungle. The lunch at the park was really good too. The trip got cut slightly short as it started pouring down, but our driver Mai, proved to be and excellent driver and got us home safe in the heavy rain.

A fun and thrilling trip through the national park - worth being very sweaty at the end of it! - We had a great experience hiking through the jungle with Surina! She was very nice and knowledgable guiding us to waterfalls, along small rivers and over sticks & stones. Thanks to her trained eye, we saw footprints of elephants (&their poop of course), marks of bears on trees, a snake as well as a few other animals during our trip. And at the end, we were even able to watch a big elephant eat calmly on one side of the road! The driver Jerawat was also really nice to us and tried his best slowing down at bumps in the road, so that we had a smooth 3-hour drive to the park (& back). We can fully recommend the trip for a great and thrilling experience during holidays :)

Mr.Paul's mood is contageous! - Mr Paul was really kind with us and also a true elephant lover. We even got lucky enough to see an elephant!

Nice, but little time at waterfall - Waterfalls are amazing. The planning and time management skills of the organisers is better to be developed, since instead of promised 4 hours at the waterfalls we were there only for 1.5 hour, which is definitely not enough to enjoy that fantastic place.
