Glen Canyon Dam & Lake Powell

Straddling the Utah-Arizona border, Glen Canyon Dam and Lake Powell form one of the American Southwest's most dramatic human-made landscapes. The 710-foot concrete arch dam holds back the Colorado River to create a shimmering 186-mile-long reservoir that snakes through vermilion sandstone canyons. This is a place where engineering meets raw geology, offering houseboat adventures, slot-canyon hikes, and jaw-dropping views from the Carl Hayden Visitor Center.

Highlights & What to See

• Carl Hayden Visitor Center: Perched on the canyon rim, this free museum and viewpoint explains the dam's construction and offers panoramic windows over the chasm.
• Dam Tour: Descend 500 feet into the dam's interior to see the massive generators and the surreal blue-green river below.
• Antelope Canyon: Just east of Page, this world-famous slot canyon (Upper and Lower) is a must for photographers, with light beams and swirling Navajo sandstone.
• Horseshoe Bend: A short, sandy hike leads to the iconic curve of the Colorado River, 1,000 feet below—best at sunrise or sunset.
• Lake Powell Boat Tours: Cruise to Rainbow Bridge National Monument, the world's largest natural bridge, accessible only by water.
• Houseboating & Kayaking: Rent a houseboat from Wahweap Marina to explore hidden side canyons like Padre Bay or the Escalante arm.

Suggested Time to Spend

Give the dam and visitor center at least two hours. Add a half-day for a boat trip to Rainbow Bridge or a self-guided kayak paddle. If you're keen on hiking Antelope Canyon and Horseshoe Bend, plan a full day. Most visitors base themselves in Page, Arizona, for 2–3 nights to cover the highlights without rush.
