Below the Dam: Kayaking Black Canyon to Hidden Hot Springs
7 Hours | Paddle 12 miles from the base of Hoover Dam through Black Canyon
The first light finds the canyon in stages: shadowed ribs of volcanic rock, then a narrow band of silver as the Colorado River begins to move. You stand on a high shelf of the original access road, helmet still warm from the van, watching guides unfurl bright kayaks like little buoys of human intent. The dam above is a hulking, precise thing—manmade masonry that hums with a century of engineering—and the river below seems to dare you to follow. Ten minutes after slipping past the security gate and signing beneath the stern gaze of National Park Service staff, the canyon tightens and the modern world drops behind you.
Trail Wisdom
Bring a government ID
A federal security checkpoint controls the Hoover Dam launch; adults must present photo ID or you may be denied access.
Wear water shoes with grip
The shoreline is rocky and scramble sections to hot springs require closed-toe footwear that can get wet.
Hydrate and pace yourself
12 miles of paddling and canyon sun can deplete you—drink regularly and use breaks to recover.
Book permits early
Only 45 participant permits are issued daily; reserve in advance to secure a launch slot.
Local Knowledge
Hidden Gems
- •Steam-filled sauna cave tucked into a side canyon
- •Small gauging station ruins from early 20th-century hydrology surveys

Conservation Note
The launch is permitted and limited to reduce impacts; visitors should follow Leave No Trace, avoid altering hot spring pools, and pack out all trash.
Hoover Dam was completed in 1936 and transformed water management and power distribution across the Southwest; Black Canyon bears both native histories and 20th-century engineering marks.
