You are allowed to camp most anywhere in Sequoia National Forest, but if you want to have a campfire or charcoal barbeque, you do need a campfire permit. They can be picked up at the Hume Lake Ranger Station or the Grant Grove Visitor Center. Also, in mid- to late- summer some years campfire restrictions do go into place and you may not be able to have a campfire at all.
In 1914 a telephone was installed at the Buck Rock lookout. At this time the lookout was nothing more than an open platform on top of the rock which was reached by climbing up a tree with steps nailed into it. In 1923 the lookout building was constructed. It is a 4-A style cab which measures 14 feet by 14 feet with windows on all sides and a steep roof. The Buck Rock Lookout was one of the last 4-A cabs built in the U.S. and is one of only 3 still standing. At this time a series of long ladders placed along the sheer granite walls had to be climbed in order to reach the lookout tower. In 1941 the ladders were replaced with a series of stairways built by the CCC and these are still in use today.
