Preah Khan Temple: Siem Reap Travel Guide (4.8★)

Most visitors burn their energy on Angkor Wat and Ta Prohm first, then arrive at Preah Khan already tired, which is a mistake. This is one of the largest ground-level ruins in the Angkor complex, laid out as a long east-west processional axis rather than a single central tower, and it rewards a slow, unhurried walk more than almost any other site here.

King Jayavarman VII built it in the late 12th century, on the spot where he reportedly defeated an invading Cham army. It served as a Buddhist monastery and teaching university, and inscriptions found on site suggest thousands of monks, students, and staff once worked here.

Walking the long axis

Preah Khan has no single dominant tower like Angkor Wat. Instead you move through a sequence of gopuras (gateway towers), courtyards, and galleries stretched along a roughly 800-metre east-west line.

The carvings are the reason people rate this place so highly. Look for:

• Apsara dancers carved in relief along the walls
• A two-storey structure with round columns near the eastern end, thought to have been a granary or library
• Tree roots from silk-cotton and strangler fig trees fused directly into the stonework, left deliberately unrestored in sections

Give yourself 45 to 75 minutes minimum. Rushing the corridors means missing the carvings that survive only because this part of the complex gets less foot traffic than the headline temples.

When to go to avoid the crowds

Preah Khan is well-known enough that tour buses build it into standard multi-temple itineraries, so it does see steady traffic. Weekdays are consistently quieter, with manageable crowds any time between 8am and 6pm.

Weekends are the opposite: try to avoid arriving between 9am and 5pm, when guided groups cluster around the eastern entrance and the main corridor. If a weekend visit is your only option, aim for right at opening or the last hour before closing.

Because the site is open until 6:30pm daily, a late-afternoon visit also gives you softer light through the tree canopy without competing with the sunrise crowds gathered at Angkor Wat.

Getting there and combining it with other temples

Preah Khan sits north of Angkor Thom and the Northern Group of temples, making it a natural pairing with Neak Pean and Ta Som on a “small circuit” tuk-tuk route. Most drivers include it as a stop rather than a standalone trip.

You’ll need the multi-day Angkor Pass to enter, the same ticket that covers Angkor Wat, Bayon, and Ta Prohm; there’s no separate admission for Preah Khan. Confirm current pass prices and entry rules before you go, since these are adjusted periodically.

The main entrance is on the eastern side, which is also where most tour groups congregate. Entering from the western gopura instead gives you a quieter, reverse walk through the temple before meeting the crowds coming the other way.

Reading the ruins without a guide

Preah Khan’s layout can be confusing on a first pass because the galleries branch and double back rather than running in one straight line. A rough map or a guide’s explanation helps you find the granary structure and the best-preserved carving panels rather than wandering past them.

If you hire a guide at the entrance, agree on a price before starting; rates aren’t posted and vary by group size and language. Independent travelers can also pick up a printed Angkor guidebook in Siem Reap town beforehand, which covers Preah Khan’s layout in more detail than the on-site signage does.

What to bring for the walk

The corridors are shaded by tall trees for long stretches, which makes Preah Khan more bearable at midday than open-air sites like Angkor Wat’s central towers. Still, the ground is uneven sandstone and packed earth, often damp near the tree-root sections.

• Closed shoes with grip, not sandals
• A refillable water bottle; there’s limited shade-free walking but the heat still adds up over an hour
• Shoulders and knees covered, as with any active religious site in the complex

Wear modest clothing even though Preah Khan functions today mainly as a ruin rather than an active place of worship. Small shrines and Buddha images remain in use in parts of the complex, and local staff do enforce basic dress standards at the entrance.
