Lake Powell is a vast reservoir on the Colorado River straddling Utah and Arizona, its red sandstone canyons flooded to create nearly 2,000 miles of shoreline. Houseboating is the classic way to experience it, weaving between towering rock walls and side canyons like Antelope Canyon's slot canyons nearby — though the lake's dramatically fluctuating water levels in recent years have reshaped parts of the shoreline.

What is houseboating like?

Multi-day houseboat rentals are popular, allowing visitors to anchor in remote canyons; advance booking is essential, especially in summer.

Is Antelope Canyon part of Lake Powell?

It's nearby, near Page, Arizona — a separate slot canyon attraction on Navajo land requiring a guided tour, often combined with a Lake Powell visit.

Prolonged drought has significantly lowered water levels in recent years, exposing previously submerged features and affecting some marina access — check current conditions before planning a trip.

Traveler reviews

★★★★★

Houseboating for four days was unforgettable — anchoring in a quiet side canyon at sunset with the red rock glowing was incredible.

Greg S. · June 2024

★★★★☆

Water levels were noticeably lower than in photos we'd seen, but the lake and canyons were still spectacular. Worth checking conditions before booking.

Patricia L. · August 2023

★★★★★

Combined a couple of nights at Lake Powell with an Antelope Canyon tour from Page — an amazing few days in a landscape unlike anywhere else.
