3. Lake Chelan, Washington

The longest natural lake in Washington and the 3rd deepest lake in the US, Lake Chelan was formed when a glacier-carved valley flooded, and it’s 1,500 feet deep and 55 miles long. Summer sun, blue skies and clear waters have made Lake Chelan of the best summer-vacation destinations to visit.

On the southeast end of the lake, there’s the remote town of Stehekin, which you can reach only by plane or boat. There is plenty to see and do in Stehekin, so consider visiting this town too.
