Kayak the Hoover Dam: Sauna Caves, Hot Springs & Black Canyon Waterfalls
Launch from the base of Hoover Dam and paddle a 12-mile stretch of the Colorado River where geothermal steam, emerald caves, and tiered hot springs punctuate black canyon walls. This full-day guided trip combines calm current paddling with short hikes, rope-assisted slots, and all the access you can’t get on your own.
The Experience
Before You Go
Start early for cooler temps
Morning launches avoid the worst desert heat and give better light for the emerald-water shots.
Wear grippy water shoes
Short hikes and wet rock scrambles require shoes with good traction—flip-flops are not sufficient.
Hydrate and salt-up
Bring at least 1–1.5 liters of water and electrolyte replacement; hot springs and exertion dehydrate quickly.
Follow guide instructions in geothermal zones
Some pools and waterfalls exceed safe bathing temperatures—only enter where the guide confirms it’s safe.
Local Knowledge
Hidden Gems

- •Emerald Cave entrances and small back-beaches that glow in low sun

Conservation Note
This is a managed corridor—stay on established access, pack out waste, and avoid disturbing fragile geothermal pools to protect aquatic life and water quality.
Hoover Dam’s construction in the 1930s reshaped the Colorado; Black Canyon’s hot springs were mapped and later restricted as dam projects developed.

Common Questions
Where do we meet and is there a parking fee?
Meet at Willow Beach Marina or Hoover Dam Lodge far-left parking lot; Willow Beach has a $25 entry fee unless you have a National Parks pass.
How physically demanding is the trip?
Moderate: paddling 12 miles with a slow current, plus several short hikes and light scrambles; guides assist technical sections.
Are children allowed?
Families are welcome; some sections require caution—guides will advise which stops are suitable for younger kids.
Can I hike the hot springs in summer?
Many onshore hikes are closed in summer due to extreme heat; the outfitter navigates river access so you still see heat-affected features by water.
What safety measures are in place around geothermal sites?
Guides assess temperatures and access; you should only enter pools or approach waterfalls at their direction to avoid scalding risks.
Can I bring a camera or phone?
Yes—waterproof cases or dry bags are recommended; the outfitter often points to the best photo stops and manages onshore breaks for shooting.
