Starting among ancient petrified sand dunes, this guided Moab canyoneering trip hikes downhill into a dry sand-and-rock wash that plunges over an edge into a hidden chasm; participants descend via a series of dramatic rappels into a grotto and then through an alluring green canyon, accompanied by interpretation of the area’s geology and a spring-fed stream that cools the route.
Nestled in the heart of southeastern Utah, Moab is a magnet for adventurers seeking to conquer rugged landscapes and discover its hidden secrets.

Route Schematic
Route Schematic & Key Stops
A sequence of distinct travel moments marks the route: dune country, a plunging wash, technical rappels into the grotto and below a natural stone bridge, then a stream-lined canyon hike.
Petrified Sand Dunes
The trip begins among ancient, lithified sand dunes where the hike first descends toward the wash and guides set context on geology and plant life.
Dry Wash & Overhanging Edge
A dry sand-and-rock wash leads to an edge where the ground falls away into a hidden chasm—this overlook precedes the first rappel.
The Grotto (First Rappel)
A deliberate, instructional rappel drops participants into the nearly enclosed stone room called the Grotto, the initial technical obstacle on the route.
Natural Stone Bridge & Green Canyon Rappel
Exiting the Grotto, the route includes an impressive rappel via an enormous natural stone bridge into a green-walled canyon, followed by a hike along a spring-fed stream.
This trip includes multiple rappels and downhill hiking; guides provide detailed instruction and a back-up safety system so even first-time canyoneers can participate, but expect technical exposure and physical movement on uneven rock.
