43. Arlington National Cemetery – Virginia
Sure, it might sound strange to add a national cemetery as a vacation spot. However, it’s an American destination everyone should visit at least once. Located outside Washington D.C., the cemetery covers at least 624 acres dedicated to the graves of service members, veterans, and even a few deceased presidents (via Oyster). Stick around long enough and you’ll witness the Changing of the Guard that takes place every 30 or 60 minutes depending on the time of the year (via Oyster).
