The following cliffs will be closed to climbing beginning March 1, 2012: Angels Landing, Cable Mountain, The Great White Throne (beyond single- and double-pitched climbs), Isaac (in Court of the Patriarchs), The Sentinel, Mountain of the Sun, North Twin Brother, Tunnel Wall, The East Temple, Mount Spry, The Streaked Wall, Mount Kinesava, and the Middle Fork of Taylor Creek. All other cliffs will remain open to climbing.
Kolob Canyon is the "other" Zion. Part of the park, but accessed via a separate entrance, this area encompasses the less-explored but equally spectacular northern reaches of the Zion. The canyon is home to many long routes, both free and aid, as well as a great sport climbing crag and some high quality bouldering.
This area feels untouched and has a strange beauty about it. Expect to get out of this area what you put into it. Weather can be a little more alpine as Kolob sits at a much higher elevation than the main area.
17 miles north of Toquerville on I-15 from Toquerville; this is as if you were leaving Zion's main canyon and driving towards Cedar City.
