18. Lake Tahoe
Where: California and Nevada
Why We Love It: Not only is Lake Tahoe a gorgeous place in the United States, but you can also visit two separate states when you go see it – all in one day. Why? Because the stunning lake is on the border between California and Nevada.
Located in the Sierra Nevada Mountains, it’s a large freshwater lake with several beautiful beaches and ski resorts to check out. You can also stop and check out the 1929 Nordic-style mansion Vikingsholm and see 70 feet into the water.
