This is another example of a series of caches that I published as a set that were a natural to turn into a GeoPath.Established in 1936 by executive order of President Franklin D. Roosevelt, the Patuxent Research Refuge is the nation's only national wildlife refuge established to support wildlife research. The National Wildlife Visitor Center is a science and environmental education center providing visitors with opportunities to explore, discover, and learn.
There are 6 caches in this GeoPath, but you'll only need to find 5. This is to allow you to complete it even if you visit when the actual Visitor Center is closed.
If you are in the area, this can easily been completed in a couple hours or so.
