Nobody has sent me a picture of Big Run. If you have been, that is the one thing I cannot get by ringing anyone up —send one and it goes on this page with your name on it if you want it.

No reservation needed

Not on Maryland DNR's list of parks requiring day-use reservations as of 25 June 2026. Day-use fees may still apply on arrival.

Three hundred acres at the mouth of the Savage River where it meets the reservoir, surrounded on all sides by Savage River State Forest. Primitive camping, and the put-in for some of the most serious whitewater in the mid-Atlantic when the river is released.

Primitive camping where the Savage River meets the reservoir, wrapped on every side by state forest. There are restrooms and picnic areas, which for a site this rough is more than you'd expect.

    Bears on: restrooms, picnic, camping

First-hand and useful, but not the same as the agency confirming it — so it doesn't change the stamp below. It changes what I go and ask.

Field notes

What I saw on the day. Not checked with anyone, and it can go out of date faster than the facts above.

  • Field note · 6 August 2026 · Site maintainer

    Pets were unconfirmed here while the park's own warning said "pets must be leashed and with their owner" — a rule about how to keep a dog is Maryland DNR saying you may bring one. Read as yes. The new dogs page is what put the two side by side; on the park page they sat in different blocks and nobody noticed.

Still open — tap one

Not published. A person reads it, and if I can use it, it becomes a dated fact here. How that works.
