Studded with stalactites, the Khao Luang Cave is filled with Buddha images, including a 10-meter-long reclining Buddha. Most were put in place by kings Rama IV and Rama V. The cave is best appreciated on a clear morning, between 9 and 10, when the sun shines in and reflects off the brass Buddha images. For a donation of B20 or so (to pay for the electricity), the nun will light up the rear of the cave for you. The cave is accessed via a two-minute walk from the parking lot and some steep stairs. Watch out for the monkeys. A large monastery, Wat Tham Klaep, at the bottom of the hill below the cave, is open to the public.
