The nature trail at the South campground is about half a mile and not very interesting. The boardwalk at the northern campground (Visitor Center) is also about half a mile and very scenic.
The boardwalk at the nature center is about 1/4 mile? And the nature trail at Grassy is a mile neither one are hard trail's very easy to walk with benches to rest on hope this help's and there is also a trail at the welcome center it's on the way to Grassy!:)
