There are two main rock-climbing crags on the conglomerate rock at Maisan. Both are accessed from a side trail just past the lake (both lake and trail are on the right) if you head towards the temples from the "small entrance". Opera House is a massive, overhanging amphitheater with routes from 5.10+ to 5.14. More routes are being added, especially on the "side annexes". The turnoff is just behind the sign on the main road-- it's a faint path that leads up and around to the main rock. Albawi is a moderate crag -- turnoff a few minutes up the main path. It has moderate routes of 1-3 pitches, ranging from 5.8 to 5.10. If you want to climb, bring a helmet! More information can be found on www.koreaontherocks.com
It's also possible to camp, though the campgrounds are often reserved for groups. As a large group of mostly foreign climbers, we reserved for a gathering and were treated royally. This beta is courtesy of my friend Jake for the camp-ground just by the lake area. Call (or have someone call) ahead. They have tents and sleeping bags for those without their own. Prices are below, valid 2008-10-04. If you are camping here, then you can usually get free access to the park and drive right up (but you need to call the Management Office and Campground in advance).
