Imagine an impossibly narrow canyon with sinewy curved and twisted wind-swept paths, lit with mysterious shadows and hints of light, that tempt canyoneers to wiggle, slither and climb to its finish. Birch Hollow is such a canyon, yet it’s a forgotten gem in the canyoneering world, because it doesn’t hold the stigma of being within the Zion National Park boundary. Not only does Birch Hollow offer some of the best canyoneering to be had anywhere, it can be combined with two of Zion’s magnificent classic canyons, Orderville Canyon and the Zion Narrows.
