We had one more day to spend in Hua Hin, so Evan, Hannah and I went to the Sam Roi Yot National Park to go to the Phraya Nakhon Cave where a Thai king had built a pavilion. After arriving at the national park, we took a short boat ride to the beach where the hike to the cave began. It was a short hike, but it included a lot of stairs and the weather that day was very hot and humid. However, the cave that we arrived at was incredible and it was completely worth the hike. This was possibly one of the most beautiful places I have ever been (right up there with Cinque Terre in Italy) and pictures do not do it justice.
After walking around in the cave we hiked back down to the beach, had lunch at a little restaurant they had there for people who camp in the national park, and rode the boat back to where our taxi was waiting to take us back to the hotel.
Here are some pictures from that day:
