Shortlist · Green Ridge State Forest, Maryland

Campsites beside running water

27 of the 99 campsites with a page qualify.

Not the river page. The Potomac is nine sites at the bottom of the forest; this is every pitch with running water inside 500 ft of it, which is mostly Fifteenmile Creek and the unnamed runs that feed it. Close enough to hear from the tent.

The app’s water tag is campers’ judgement; this page is the measured distance, so the two lists differ a little.

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

A mapped watercourse within 500 ft of the pitch, measured to the nearest point on it.

The test
A mapped watercourse within 500 ft of the pitch. Distance is to the nearest point on the water, not to a named place on it.
Where it comes from
Watercourses from OpenStreetMap; the distance from the pitch measured against the USGS 3DEP model. A stream with no name in the data is called running water here rather than given one.
What it does not mean
None of this is drinking water — there is no potable supply anywhere in the forest and you bring what you need. Nor is it permanent: the smaller runs go dry in a hot summer, and a creek 200 ft away can be a dry bed in August.

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

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.
