4. Lake Powell – Arizona & Utah
Lake Powell is a massive reservoir created by the Glen Canyon Dam. What makes it special is how the water winds through deep red rock canyons, forming countless inlets and hidden corners. The lake is popular for houseboats, paddleboards, and scenic hikes nearby like Antelope Canyon.
Its landscape combines water and desert in a way that’s unlike any other place in the country. The mix of still water and massive cliffs makes it a favorite for outdoor adventures and dramatic photo spots.
