7. Bear Lake, Kenai Fjords National Park, Alaska
There is a reason why Bear Lake stands out as one of the best lakes in a state with over 3 million lakes. Throughout the year, you can enjoy hiking and kayaking around and on the lake. There are massive glaciers that you can paddle through and around, as well as ice-skating and dog sledding. But the best part? Sometimes you can even see the Northern Lights dancing above the lake.
