Borobudur, built in the seventh and eighth centuries, consists of six square platforms decorated with more than 2,500 relief panels and some 500 Buddha statues, making it one of the most decorated temples on earth. Guided tours of the complex uncover the stories behind the imagery while giving visitors a better understanding of nirvana, karmic laws, and the life of Buddha. You can choose between intimate small-group tours, private tours, or combo tours that might include cycling through nearby villages, rafting on the Progo River, or visits to Pawon and Mendut Temples. If you have some extra time, opt for a two-day tour that includes a visit to Prambanan, a UNESCO-listed Hindu temple.
