We enjoyed Grand Tetons NP a lot - much quieter than Yellowstone up the road, good camping and great rafting adventures. Lesser known is Acadia NP in Maine on the Atlantic coast. Great hiking in a variety of settings - mountains, ocean shoreline, meadows and woods. For variety, see the alligators and birds in Everglades NP between Naples and Miami.
