Lake Powell, stretching across the Utah-Arizona border, is one of the largest manmade reservoirs in the United States. Formed by the flooding of Glen Canyon after the completion of the Glen Canyon Dam in 1963, it covers over 180 miles in length and contains nearly 2,000 miles of shoreline, more than the entire West Coast of the U.S. Despite its modern origins, the area has long been home to the Ancestral Puebloans and later Navajo communities. Ancient petroglyphs and cliff dwellings can still be seen in the canyons that rise above the water.

The lake is best known for its maze of narrow canyons, sandstone arches, and dramatic cliffs that reflect the sun in changing shades of red and gold. One of the most photographed spots is Rainbow Bridge National Monument, accessible by boat or a challenging hike. Towering nearly 300 feet, the natural rock span is considered sacred by several Native American tribes and is one of the largest natural bridges in the world. Other highlights include Antelope Canyon, Wahweap Bay, and the lesser-known Labyrinth Canyon, which offers a quiet, winding paddle route.

Recreation on Lake Powell is centered around water, and houseboat rentals are a major draw. Many visitors spend several days cruising, swimming, fishing, and anchoring in secluded coves. Campgrounds and marinas such as Bullfrog and Wahweap provide launching points and supplies. The fishing here is excellent for striped bass, walleye, and crappie, with spring and fall offering peak conditions. Stand-up paddleboarding and kayaking are popular for exploring side canyons that boats can’t reach.
