Explore a Slot Canyon. While hikes like Angels Landing or Observation Point satisfy the macho, goal-oriented hiker, Hidden Canyon is more of a sublime, spiritual experience. A nice place to while away a few hours on a hot summer day, the beautiful, well-shaded grotto offers no specific objective - and is better for it.
The trail to the mouth of Hidden Canyon (HC) was constructed in 1928, when trail designers Guy D. Edwards and F.A. Kittredge set out to provide access to a hanging canyon. The men designed the trail to blend in with exisiting landscape features, and largely succeeded, creating a trail largely invisible from nearby vistas. Like its sibling across the way, the HC Trail is hewn into a steep rock buttress, with chains anchored to the rock for security. Don't bring small children or the faint of heart.
Hidden Canyon also makes a fine, moderate technical canyoneering adventure. See Hidden Canyon from the Top under Technical Canyons.
