If you only have time for one stop in Phetchaburi, many visitors pick Khao Wang, since it combines a historic palace, a temple, a stupa, and a city viewpoint all on a single hill. Phra Nakhon Khiri sits right beside Phetkasem Road in the middle of town, just minutes from the city centre, and about 2 hours from Bangkok, making it an easy stop on a day trip.
The hill itself is split into three peaks, each with its own structures, which makes the walk around more absorbing than you might expect. On this page we review in detail what you'll find as you climb, what's on each peak, which route up is best, and what to keep in mind before you go — covering both what reviewers praise and what they flag as drawbacks.
Phra Nakhon Khiri Historical Park (Khao Wang), Phetchaburi — Hilltop Palace on 3 Peaks + Cable Car
Phra Nakhon Khiri is a summer palace that King Mongkut (Rama IV) had built atop a tall hill in the middle of Phetchaburi. The hill is divided into three peaks, each holding a different set of important structures. The western peak is home to the group of royal residences, a museum displaying historic royal artifacts, and the observatory (Ho Chatchawan Wiangchai), which Rama IV used to study the stars, reflecting his well-known interest in astronomy. The central peak holds Phra That Chom Phet, a bell-shaped white stupa visible from a distance, while the eastern peak is home to Wat Phra Kaew Noi, the palace's own temple. A point reviewers frequently mention is the architecture, which blends Thai, Chinese, and Western styles, clearly reflecting the tastes of Thailand's era of opening up to the world.
There are two ways up Khao Wang. The first is the cable car (funicular), which runs up and down all day and is convenient for elderly visitors, young children, or anyone who'd rather not tire themselves out. The other option is climbing the stone staircase, which is fairly steep and takes some effort, though it offers a shaded, pleasant walk along the way. Park entry and the cable car fare are charged separately, and Thai and foreign visitors pay different rates, so it's worth having cash ready for both. At the top, walkways connect the three peaks so you can see everything in a single loop. Once you reach the summit you get a panoramic view over Phetchaburi, taking in the river, temples, and rice fields spread around the town. Late afternoon, before sunset, is when the light softens and the views look their best, while midday sun tends to be quite strong since the hilltop area is open and exposed. Many visitors make Khao Wang their main stop, then continue on to try Phetchaburi's famous sweets and visit Khao Luang Cave on the same trip.
One thing worth knowing plainly before you go: Khao Wang is home to a large troop of monkeys. They're used to people and can be fairly bold, often snatching food bags, water bottles, glasses, or anything held in your hands. Keep valuables well out of sight, avoid carrying visible plastic bags, and don't feed them. Getting around the hilltop involves a fair amount of up-and-down on stairs and stone slopes, so comfortable, sturdy walking shoes make a real difference. Anyone choosing to walk up rather than take the cable car should bring enough energy and water, since the stairs are steep and the weather can be hot. Inside the royal residences you'll need to remove your shoes and any hat, and dress modestly — no bare shoulders or shorts above the knee. Another point reviews mention is that parts of the buildings and walkways are periodically under restoration, and the park tends to close fairly early in the evening, so it's worth checking opening hours in advance.
- A hilltop palace from the Rama IV era with a Thai-Chinese-Western architectural blend, plus an observatory, Phra That Chom Phet, a museum, and a temple all in one place

- Centrally located and easy to reach, easily combined in one trip with Phetchaburi's famous sweets and Khao Luang Cave
- Plenty of monkeys, and fairly bold ones — they often grab at food bags, water bottles, and anything held in your hands, so valuables need to stay out of sight at all times
- If you choose to walk up rather than take the cable car, the stairs are steep and involve a fair amount of climbing; midday sun is strong since the hilltop is open and exposed
- Entry and cable car fees are charged separately, with foreign visitors paying more than Thais; some areas are under restoration, and the park tends to close fairly early in the evening
💡 Know before you climb Khao Wang (Phra Nakhon Khiri)
The stone staircase up the hill is fairly steep and takes real effort. If you're bringing elderly relatives or young children, or just don't want to tire yourself out, take the cable car (funicular) instead — far more convenient and much less exhausting.
Khao Wang has a troop of monkeys that are used to people and fairly bold. They like to grab food bags, water bottles, glasses, and anything in your hands. Keep valuables out of sight, don't carry visible plastic bags, and never feed them.
The hilltop area is open and exposed, so midday sun is strong and there's a lot of walking. Go in the morning or late afternoon when the sun is softer and photos look better. Bring a hat, sunglasses, and water.
Park entry and the cable car fare are billed separately, with different rates for Thai and foreign visitors. Bring cash, and check opening hours before you go since the park tends to close fairly early in the evening.
