Michigan's Upper Peninsula
Lonely Planet recently named the Upper Peninsula of Michigan one of the world's best value destinations. Marquette is where much of the action is, Copper Harbor is known for mountain biking trails, and shipwrecks off the coast entice divers.
Check out nearby Pictured Rocks National Lakeshore or venture to Isle Royale National Park to find lighthouses, dramatic stone cliffs, waterfalls, and more. Hotel rooms go for less than $85 a night depending on the season.
