great place to climb for a week. the local climbing shop/guide service called Chiang Mai Rock Climbing Adventure gives rides to/from the crag for 200 baht including a great lunch, fully worth it.
Great area for some good limestone sport routes. i went a few years back with the chiang mai rock climbing adventures. the guides gwang and taw (if they are still there) are THE BEST! they also have a small bouldering wall at the store. agreed with the awesome food. just watch out for the biting ants! overall great climbs... i highly recommend 'magic drop.'
