The morning light pours across flat rice paddies as a convoy leaves Siem Reap; dust and distant motorbike hum give way to a quieter landscape the farther north you go. By the time the road gives up to red dirt, the ruins of Koh Ker appear — a lone pyramid rising where a brief Khmer capital once tested new forms of temple architecture.

History
Koh Ker served briefly as Khmer capital in the 10th century under Jayavarman IV; Beng Mealea dates to the early 12th century and mirrors Angkor Wat’s layout while remaining partially unrestored.
Conservation
Both sites face pressure from weathering and vegetation; visitors should avoid climbing on fragile carvings, stick to paths, and support local guides to help sustain responsible tourism.

Hydrate and carry backups
Bring a 1–2L refillable water bottle and use the bottled water provided — there are long stretches without services between sites.
Grip for uneven stone
Wear sturdy shoes with good traction; temple floors and stairways are often irregular, broken, and slippery when wet.
Sun management
Bring a wide-brim hat and sunscreen — shade is limited at Koh Ker’s summit and open courtyards at Beng Mealea.
Cash and respect
Carry small Cambodian riel or USD for local vendors, donations, and restroom fees; follow guides and avoid touching fragile carvings.
Sturdy walking shoes
Provide traction and ankle support on broken stone and muddy approaches.
