Preah Khan Temple, a significant complex within the Angkor Archaeological Park, offers a captivating experience, blending restored sections with areas where nature has reclaimed structures, similar to Ta Prohm but on a grander scale. Access involves walking on uneven stone pathways and navigating steps, typical of ancient ruins, making it challenging for those with significant mobility issues but generally accessible for others. While solo exploration is rewarding, a local guide can greatly enrich the visit by providing historical context and explaining the intricate carvings and layout. The best time to visit is during Cambodia's dry season, from November to April, to avoid the intense rains and humidity of the monsoon season. Entrance is covered by the Angkor Pass (e.g., ~$37 USD for a 1-day pass, prices subject to change), with no separate fee for Preah Khan itself. Visitors typically spend 1.5 to 2.5 hours exploring its extensive courtyards, sanctuaries, and unique two-story structures. Comfortable footwear, water, and sun protection are highly recommended for this sprawling, partly unrestored temple that often feels less crowded than the main Angkor temples, offering a more serene exploration.
