Hua Hin

Hua Hin is the only province in this dataset that already has a temple, a real waterfall and a dramatic cave all independently verified: Wat Khao Takiab's hilltop shrine, Pa La-U's sixteen tiers, and Phraya Nakhon's sunbeam-lit royal pavilion. Nothing else in the dataset stacks all three, so this is the best match on the original ask, at the cost of a long day of private-car driving between three sites that sit far apart.
