A very nice trip overall! We're so glad we got to see Erawan especially since we were staying in Bangkok. We would have liked more time at the National Park, rather than at the Museum/railway, the museum was very, very dated and small, quite run down, but important to see. Lunch was expensive and not that tasty, we would have preferred to browse the various lunch options at Erawan.
The national park itself was stunning, gorgeous waterfalls and we loved swimming at different levels. You need to pay 20baht to rent a lifejacket if you want to swim. I'd recommend hiking the waterfall first to see where you want to swim, rather than carrying the lifejacket, then hire one and go straight to the level you want to swim at.
We wished our guide gave us more information about the trip and was more engaging with the group, it was more of a charter bus than a tour. But great experience and thank you for a wonderful time! 🥰
