Hawaii: Na Pali Coast
Once home to ancient Hawaiian communities, the Na Pali coast is characterized by sharp peaks and mountains that fall steeply to the ocean, forming deep valleys, caves, and cliffs. The only ways to see the coast are by helicopter, boat, or hiking a gruelling 11-mile trail over the steep ridges.
Idaho: Sawtooth National Forest
The Sawtooth National Forest is home to over 300 alpine lakes amongst dozens of 10,000 foot snow-capped peaks, and over 700 miles of trails. While Sawtooth is a haven for all types of outdoor sports and activities, those who wish to see it firsthand from the comfort of a vehicle can drive the Ponderosa Pine Scenic Byway.
Illinois: Garden of the Gods
These 300-million-year-old sandstone formations in the Shawnee National Forest are accessible by a quarter-mile observation trail and are one of the most photographed locations in Illinois.
Indiana: Indiana Dunes
Spanning 15 miles of coastline on the southern shore of Lake Michigan, Indian Dunes National Park has over 50 miles of dune trials, as well as beaches, wetlands, rivers, forests, and prairies.
Iowa: Upper Iowa River
The Upper Iowa River traverses part of what is known as the Driftless Area, a region untouched by glaciers during the last ice age, which has left the land with intact ancient topography. High bluffs surround this stretch of water, which is a popular area for kayaking and canoeing.
