Bayon Temple, located within Angkor Thom in Siem Reap, Cambodia, is a must-see for its iconic smiling stone faces and intricate bas-reliefs. While the general park is accessible, the temple itself involves climbing steps and navigating uneven surfaces, limiting wheelchair access. Visitors can explore solo, but a local guide is highly recommended to fully appreciate its historical and cultural significance. The temple is open year-round, with the dry season (Nov-Apr) offering pleasant weather but more crowds, and the wet season (May-Oct) providing lush scenery and fewer tourists. Entry is covered by the Angkor Pass (e.g., ~$37 for a 1-day pass), and a visit typically lasts 1-2 hours, often as part of a larger Angkor Thom tour. Arriving early morning or late afternoon is advisable to avoid peak crowds and capture optimal lighting for photography. Remember to dress modestly, covering shoulders and knees.
