On a forested hillside at the edge of Phetchaburi, Phra Nakhon Khiri Historical Park (Khao Wang) includes one of King Rama IV’s palaces and a series of temples and shrines.
Many of these are set high on the hilltop and have good views. Monkeys are a major shoplifting hazard around the gift shops at the foot of the hill.
There’s a cable car for those who don’t fancy the strenuous walk.
