Once you have found the units in the National Park System you plan to visit there are numerous links on each unit’s webpage that can be helpful to you. There are links to “Plan Your Visit,” “Directions,” “Operating Hours and Seasons,” “Fees and Reservations,” “Things to Do,” “For Kids,” and much more. Some of the units will have a link for “Nearby Attractions” that can be found after going to the “Things to Do” link. This link can be very helpful, take the Nearby Attractions link for Homestead National Monument of America for example; it provides links to nearby state parks, camping, and other units in the National Park System. In addition it provides links to appropriate visitors’ bureaus, airports, and tourism agencies.
The National Park System isn’t the only agency that administers federal lands that you could visit. The best place to start for ideas is Recreation.gov. But you could also check these sites: Department of Interior Plan A Trip, U. S. Forest Service homepage, and U. S. Army Corps of Engineers Recreation Page.
