War Museum Cambodia in Siem Reap offers a sobering look at the country's turbulent past, showcasing an extensive collection of military hardware, including tanks, artillery, and small arms. Accessibility can be limited due to uneven terrain. Visitors can explore the museum solo or opt for a guided tour to gain deeper insights from knowledgeable locals, often former soldiers. There are no significant seasonal restrictions, though the dry season (November to April) offers more comfortable weather for outdoor exploration. Expect to spend approximately 1-2 hours at the museum, and the entrance fee is generally around $5-10 USD. It provides a poignant and educational experience, shedding light on Cambodia's history and the impact of conflict.
