Had a great visit to a national park about one hour south of Hua Hin.
The drive down is easy with good highway and roads but we appreciated our GPS. The park costs 200 Baht per person and you are asked to show the tickets at a few stops. We first took a canal long-boat ride which was through a quiet area of mangroves. Pretty and saw monkeys, lots of birds, crabs and mudskippers.
Then we headed to a beach area and sat at an outside restaurant overlooking the beach. Good food and cheap plus no one at the beach which was great.
Then it was on to take another long-boat out to another secluded beach. From there you can climb up pretty tough steps hewn out of rock to reach caves with a temple inside. This is a tough climb in the heat.
The beaches are lovely and again were empty. It was a great day out.
