Phimeanakas, located within the ancient city of Angkor Thom, is a Hindu temple built in the 11th century, taking the form of a stepped pyramid. Access to the upper levels involves climbing steep steps, making it less accessible for individuals with mobility challenges. Exploring the temple can be done solo, allowing for independent discovery, or as part of a guided tour for historical context. There aren't specific seasonal restrictions affecting visits, but the dry season (November to April) offers more comfortable weather. Entrance to Angkor Thom, which includes Phimeanakas, requires an Angkor Pass, with prices varying depending on the number of days (approximately $37 for one day, $62 for three days, and $72 for seven days). A typical visit duration is around 1-2 hours, depending on your interest in the historical details and exploration of the surrounding Angkor Thom complex. Be aware that the steps can be quite steep and challenging to climb.
