A Full-Day Black Canyon Kayak Tour with Hot Springs and a Sauna Cave
Paddle twelve flat-water miles below Hoover Dam to a steam cave, hot springs, and beaches reachable only by boat.
Black Canyon begins at the base of Hoover Dam and runs south toward Willow Beach. The Park Service designates the stretch as the Black Canyon National Water Trail, and the walls along it climb as much as fifteen hundred feet above the river.
This trip covers twelve miles of that canyon in about seven hours. The launch sits at the foot of the dam, reached by the original road cut into the rock while the dam was going up in the 1930s. Access there is permit-controlled, and that shapes how you book.
Evolution Expeditions runs the trip out of Boulder City and secures the launch permit as part of the booking. The boats are seventeen-foot Prijon touring kayaks with rudders and padded seats: singles for paddlers with some experience, tandems for everyone else. Lunch is catered and you choose it when you book.
The company says its guides hold CPR and Wilderness First Aid certification and pass rescue, weather, and paddling tests before they lead a trip.

There is no white water below the dam. The river runs flat, and the operator is plain about what that means: nothing pushes you downstream, so twelve miles is twelve miles of paddling. It calls this a real physical day and asks that you be reasonably fit.
The water sits in the low fifties Fahrenheit all year. In July that is the best thing about it. In January it is the reason you stay in the boat.
You will get wet to the knees either way. Cotton and denim are the wrong call. Water shoes or old sneakers work, and flip-flops do not.
Life jackets come with the boat, and on this stretch wearing one is not optional: the Park Service requires every person in a hand-propelled craft between the dam and river mile 43 to wear a Coast Guard-approved jacket while under way.
The Cave Steams, and the Springs Sit Up a Side Canyon
Partway down, the route stops at a cave in the canyon wall that fills with geothermal steam, and at hot spring pools set back in the side canyons. Reaching the springs means a walk up a rocky wash from the water's edge. Wear a swimsuit under your clothes.
The land trails down to several of these springs shut from the middle of May to the end of September every year. The Park Service notes they stay open to anyone arriving by water, which is the way you are arriving.
There are beach stops too, on gravel bars no road reaches. Bighorn sheep come down to drink along this stretch, and the 1921 gauging stations the surveyors bolted into the rock are still there.
The operator lists Emerald Cave as a stop only if the day runs ahead of schedule. Plan the trip without it and enjoy it if it happens.
Forty-Five Permits a Day, and They Go Early
The launch is capped. Park Service concession documents put the limit at forty-five paddlecraft a day, released in three slots at seven, eight, and nine in the morning, fifteen boats each. The operator says the permits go first come, first served and sell out well ahead. Your booking is not confirmed until that permit is secured, and the company contacts you once it is.
So book early. The week of your trip is too late.
One separate thing to read before you pay: this listing is sold as a final sale, and cancellations carry no refund.
Who Gets in the Boat, and What the Gate Costs
Nobody drives to the water. Private vehicles are barred from the road into the Hoover Dam security zone, so everyone rides in on the operator’s shuttle, and the Park Service describes it as an escorted bus ride into the zone. Adults need a government-issued photo ID to clear that checkpoint. The operator says security turns away adults without one, and that children and minors are not asked for it.
Age rules split by how you reach the meeting point. Nevada law sets the shuttle minimum at eight years old or eighty pounds. Driving yourself to Boulder City carries no such floor, and the operator says its youngest paddler was four, riding tandem with an adult. Anyone under thirteen rides in a tandem with an adult, and children have to be able to sit unaided in their own seat.
One fee note, because it is easy to get wrong. Reclamation states that interagency passes, America the Beautiful among them, are not accepted at Hoover Dam. The contract governing this launch also folds a Reclamation charge and an area entrance fee into the permit itself. The operator sells two tiers and only the shuttle one names park entry in its price, so look at which tier you are buying.
📍 Self-drive guests meet at 18000 US-93 in Boulder City, roughly forty minutes from the Strip, and the pin on this page marks that address. Arrive forty minutes before the listed start time. Shuttle guests are collected from a Las Vegas hotel ninety minutes to just under two hours ahead, and set back down at the hotel ninety minutes to two hours after the paddle ends.
Either way the day ends downstream, sunburnt, and a good deal quieter than it started.
