You’ll need to make more than one visit if you really want to enjoy fall colors at Cuyahoga Valley National Park in Ohio. Different trees peak at different times, so each journey into this gorgeous forest offers a unique experience. Throughout October, maples, oaks, gums and dogwoods put on a splendid show you don’t want to miss. Photo at Blue Hen Falls by Craig Walton (http://ift.tt/18oFfjl).

Muscatatuck National Wildlife Refuge – the first wildlife refuge in Indiana created 50 years ago this week – protects habitat for more than 280 species of birds like sandhill cranes. The refuge was also instrumental to the comeback of the state’s endangered North American river otter, serving as the first release site to bring populations back to healthy numbers. This amazing landscape of lakes, marshes and creeks is a quick trip from major metropolitan areas in Indiana, Ohio and Kentucky. Photo by Susan Harner, USFWS.

From mountains to sand dunes to wetlands, Great Sand Dunes National Park & Preserve in Colorado has a terrific diversity of ecosystems. Each landscape is affected differently by the seasons. With fall descending on the park, that means patches of aspens in the alpine ranges are starting to show their gorgeous yellow colors. What a view! Photo by Patrick Myers, National Park Service.
