On the ground
Formed by Glen Canyon Dam on the Colorado River, Lake Powell winds for many miles through red-rock canyon country, with marinas and boat ramps serving as access points to the water.
Water levels at the reservoir vary year to year with drought and snowpack, which can affect ramp and marina access, so current conditions are worth confirming with the official source before you go.
