Shortlist · Green Ridge State Forest, Maryland

Campsites for a camper van or a trailer

14 of the 99 campsites with a page qualify.

Two things have to be true at once, and they come from two different places: campers have to have found room to put a van or a trailer on the pitch, and the road in has to be one you would take it down.

The app’s trait filter is an AND, so that link shows the trailer half of this list; the pop-up sites are here too.

Independent, free, and built by campers. Not a DNR service.

Booking
None. Sites are first come, first served.
Fee
$10 a night for a standard site, $20 for a group site, paid at headquarters. Maryland DNR.
Check in
Sign the sheet at headquarters when you arrive, then go to the site.
Is it free tonight?
This page cannot know. The app shows what the sign-up sheet last showed, with the photo's age.
What put a site on this list

Campers report room for a trailer or a pop-up, the road in is gravel-rated, and nothing on the approach is steeper than 12 per cent.

The test
A trailer-friendly or pop-up tag from campers, drive rating gravel, and a steepest approach grade under 12%.
Where it comes from
The pitch tags are the only thing on this page that is a judgement rather than a measurement — they come from campers who have been there. The road rating and the grade come from OpenStreetMap and the USGS elevation model.
What it does not mean
These are primitive sites with no hookups of any kind: no water, no electric, no sewer, no dump station. Nothing here is graded for a motorhome, and DNR asks anything over about 25 feet to use the main entrance off I-68 and stay off the switchbacks. Phone headquarters before bringing a big rig.

Same test, same order. Each number opens that site’s page.

The other shortlists

Every list is built from the same data, and a site can appear on several of them.

Where these numbers come from

Provenance

This list is generated from open data at build time, not compiled by hand. Nothing on it is a recommendation: it is a test, run over every campsite, with the test written at the top of the page so you can disagree with it.

  • Elevation, landform, slope, the horizon profile, sun times and the steepest grade on the approach come from the USGS 3D Elevation Program (3DEP).
  • Roads, surfaces and watercourses come from OpenStreetMap contributors, licensed ODbL.
  • Campsite coordinates and sections come from the Maryland Department of Natural Resources campsite layer.
  • Pitch tags — room for a trailer, secluded, a view — come from campers, and are the only thing here that is a judgement rather than a measurement.
  • Availability comes from nowhere, because there is no source for it. See above.

Independent, free, and built by campers. Not a DNR service. Greenridge is not affiliated with the Maryland Department of Natural Resources or any government agency, and the forest’s own rules always win.
