Why it matters
Why Khao Sam Roi Yot National Park is worth your time
The park shows another side of the Prachuap coast: limestone, wetlands and wildlife in a short drive from the resort. For visitors who want more than the beach, it offers variety.
The cave and pavilion also tie nature to royal history, giving the trip a clear focus. It also helps to be honest about effort. The marsh, viewpoints and shoreline are gentler than the cave climb, so a mixed party can split up for part of the day. Plan a driver who knows the park and agree a return time before you set out.

How to experience it
Khao Sam Roi Yot is a marine national park in Kui Buri District. Wikipedia says it was established in 1966 as Thailand's first coastal national park, covers about 98 square kilometres and lies about 58 km south of Hua Hin. It includes Thailand's largest freshwater marsh, mangroves and limestone peaks.
The best-known stop is Phraya Nakhon Cave, about 500 m from Laem Sala Beach, where a hole in the ceiling lets sunlight reach the Khuha Kharuehat pavilion built in 1890 for King Chulalongkorn. Wikipedia notes a climb of roughly 430 m to reach it. Start early and carry water.
If the cave is too much, spend time at the marsh and viewpoints and look for birds. Hire a car and driver from Hua Hin, and plan to be back before dark.
