Share the joy of crystal-clear water flowing through stunning desert wilderness on this virtual experience.


In 2014, the Secretary of Interior designated this portion of the Colorado River as a National Water Trail, making it the first in the Southwest and the first to flow through a desert. You can access the water trail through a guided tour at the base of the Hoover Dam, from Willow Beach, Arizona, or near an old mining town in Eldorado Canyon, Nevada.

As you travel the 30-mile trail, you’ll find beaches, caves, coves, hot springs, wilderness and solitude. Desert bighorn sheep and other wildlife are often seen on the cliffs along the river. Historic structures associated with the construction of Hoover Dam can also be viewed.


  • The water trail is around 30 miles long
  • Launching at the Hoover Dam (river mile 64) requires a permit
  • Paddlecraft can launch and takeout at Willow Beach (river mile 52 1/2)
  • Emerald Cave is located 2 miles up river from Willow Beach
  • The water trail ends at Eldorado Canyon (river mile 39)
Hoover Dam
Launching at Hoover Dam is an exclusive experience provided by a limited number of vendors in Southern Nevada and Northern Arizona. Visitors are escorted to the launch site on a narrated bus ride into the Hoover Dam Security Zone. Before rafting or paddling down the water trail, guides describe the engineering marvel that is holding back up to 28.9 million acre feet of water in Lake Mead. Tours range from float trips near the dam to day trips to full exploration tours. Approved vendors for Hoover Dam access are listed below.

Emerald Cave
Glide into this small cave backwards and have your camera ready. When the afternoon light is just right, the cave becomes a radiant grotto of shimmering green.
Eldorado Canyon
In the late 1700s, Spaniards searched for gold along the Colorado River. They named their camp “Eldorado” in honor of their quest for the legendary city of gold. At one time, thousands of men, driven by gold fever, lived within the narrow confines of the canyon. This was more men than in the nearby town of Las Vegas.

The Eldorado Canyon marks the end of the Black Canyon Water Trail. Paddlers must carry their watercraft ¼ mile up a desert wash to a vehicle. Those who continue south from Eldorado Canyon need to be prepared for open water, possible windy conditions and extreme temperature ranges. The distance to Cottonwood Cove is 17 miles and it is 40 miles to Katherine Landing.

The waterway from the Hoover Dam to Willow Beach is narrow. To provide a wilderness experience in this part of the park, there are rules restricting certain watercraft at various times of the year. Houseboating, water-skiing and wakeboarding are prohibited year round for safety reasons.
