Emerald Cave Kayak From Las Vegas: Willow Beach or Hoover Dam Base

The Black Canyon Water Trail

The stretch of the Colorado River below Hoover Dam is the Black Canyon National Water Trail, part of Lake Mead National Recreation Area. The National Park Service describes about 30 miles of river with beaches, caves, coves and hot springs, and three ways in: a guided tour at the base of Hoover Dam, Willow Beach in Arizona, or Eldorado Canyon in Nevada.

Emerald Cave is a small cave 2 miles upriver from Willow Beach. The park says the light turns the water green inside when the afternoon sun is right, and that you glide in backwards.

The trade-off: every kayak tour from Las Vegas uses the same river; what changes is where you get on and how far you paddle. Decide that first and the price follows.

From Willow Beach: the Short Paddle

Willow Beach is 14 miles south of Hoover Dam, off US 93 on the Arizona side, with a launch ramp and a marina that rents canoes and kayaks, according to the park. Most Emerald Cave tours start here and paddle upriver to the cave and back.

In the listings we tracked in October 2026, these guided tours cost $69 to $129. The day runs three to six hours with the drive, and one listing gives about three and a half hours on the water for a round trip of 4 to 5 miles. Some include hotel pickup from the Strip, about an hour each way; others meet you at Willow Beach.

There are also kayak rentals without a guide, listed at $69 to $89.88, where you paddle to the cave at your own pace. The one with the most reviews meets at Willow Beach and does not include pickup.

The trade-off: Willow Beach is the less expensive and shorter way to reach Emerald Cave, and you see a few miles of the canyon, not all of it. If the cave is the point, this is the trip.

From the Base of Hoover Dam: the Whole Canyon

Launching at the base of Hoover Dam requires a permit, and the park says it is offered by a limited number of approved companies: visitors are taken by bus into the Hoover Dam security zone to reach the river. From there, the longer tours paddle about 12 miles down the Black Canyon to Willow Beach, past hot springs and coves, and some stop at Emerald Cave on the way.

In the listings we tracked, these trips run seven to twelve hours and cost $199 to $315. One of the best reviewed asks you to arrive 40 minutes early for security check-in, gives no hotel pickup and says all sales are final.

If you would rather not paddle, rafts float the same water from the base of the dam: a 1.5-hour float listed at $69, and a 3-hour motorized float to Willow Beach with lunch listed at $140.

The trade-off: the dam launch gives you the whole canyon and the hot springs, and asks for a full day, a moderate level of fitness and a higher price. If you want to see the canyon without paddling, the raft is the easier way.

Fees, Ages and the Days Without Motors

Lake Mead National Recreation Area charges an entrance fee of $25 per private vehicle, valid for one to seven days, according to the park's fee page. Two of the most reviewed listings say the fee is included when you take the hotel pickup and paid separately if you drive yourself; check yours.

The ages differ by tour. The guided tour with the most reviews takes ages 12 to 80 and paddlers under 260 pounds; others take children from 4 or 5. The dam launch with the most reviews takes children from 5 and asks for a moderate level of fitness.

The river between Hoover Dam and Willow Beach is shared with boats on some days. The park keeps it free of motorboats and personal watercraft on Sundays and Mondays all year; from the Saturday of Memorial Day weekend to Labor Day, Tuesday to Saturday, there is no horsepower limit and personal watercraft are allowed.

The trade-off: a Sunday or Monday paddle is the quietest the river gets. In summer, the other days bring boat traffic, and an early start keeps you out of the afternoon heat.

Sunset Trips and Who Each Trip Suits

Sunset and night trips were listed at $109 to $199 in October 2026, some with a bonfire or lights on the kayaks.

What reviewers say about the guides and the paddle on these trips is in our article on Colorado River kayak reviews, and how to see Hoover Dam itself is in our article on Hoover Dam tours from Las Vegas.

The trade-off: the short Willow Beach trip suits beginners and families who want the cave; the dam launch suits paddlers who want the canyon. Cancellation terms vary: most refund up to 24 hours before, and some say all sales are final.
