Western Maryland — Mountains

Deep Creek Lake State Park is the gateway to Maryland’s largest lake — swimming, boating, and year-round mountain recreation. Offers 112 campsites (26 electric), 2 mini cabins, and 1 yurt (all sleep 6; electric, heat, beds; no running water; bring linens; no pets). Rocky Gap State Park is a resort destination with 278 campsites, 15 mini cabins (4- and 6-person), 1 yurt (8-person with camp pad for 15 total), the 243-acre Lake Habeeb, a swimming beach, and the Easter Hill Chalet — a furnished 3-bedroom house overlooking the lake with full kitchen and fireplaces. Swallow Falls State Park protects Maryland’s tallest waterfall — the 53-foot Muddy Creek Falls — and 360-year-old old-growth hemlocks. Green Ridge State Forest offers 47,000 acres of rugged backcountry camping.

Central Maryland

Cunningham Falls State Park boasts the 78-foot cascading waterfall — the largest in the state — plus a scenic lake with swimming beach. The William Houck Area campground has 4 mini cabins (6-person; A/C but no heat; cook outside; bring linens). Patapsco Valley State Park runs along 32 miles of river valley near Baltimore with suspension bridges. Rocks State Park features the King and Queen Seat — a dramatic 190-foot rock outcrop. Gunpowder Falls State Park offers diverse landscapes from river gorges to Chesapeake shoreline.

Chesapeake Bay & Eastern Shore

Assateague State Park — Maryland’s only oceanfront park — is famous for wild horses roaming freely along pristine Atlantic beach. 342 campsites for tents and RVs (some electric loops; most waterless). No cabins or yurts. Keep 40+ feet from wild horses — never feed them (illegal and dangerous). Secure all food in hard-sided containers. Calvert Cliffs State Park features fossil-rich cliffs dating back 10–20 million years — visitors can find ancient shark teeth washed up on the Chesapeake Bay beach below. The 1.8-mile Red Trail reaches the beach. Sandy Point State Park is the closest Chesapeake beach to Baltimore-Washington. Elk Neck State Park features the Turkey Point Lighthouse on dramatic bluffs.

Booking tip: Use the new reservation system at parkreservations.maryland.gov (launched Feb 2026). Reservations up to 365 days ahead; inventory drops at 9 AM ET daily. Assateague fills months ahead for summer — weekdays are easier. 2-night minimum on peak weekends; 3-night on holidays. No Saturday arrivals/departures during peak season unless booking 7+ nights. No pets in mini cabins or yurts.

Are dogs allowed in Maryland state parks?
Maryland state parks welcome leashed pets, but where they may go is set park by park under the Maryland Park Service Pet Policy — check each park’s designated pet areas. Maximum leash length is 6 feet in designated pet areas and 10 feet in undeveloped areas; swimming off-leash under voice control is allowed only in designated areas. At most parks pets are barred from sandy swim beaches from Memorial Day weekend through Labor Day; many parks allow shoreline swimming outside the swim beach. Most cabins are pet-free, but select parks designate pet-friendly cabins (e.g. Herrington Manor cabins 1-10, New Germany cabins 3-7). Pets not allowed in park buildings or playgrounds; pets must be licensed and vaccinated. Rules verified July 2026 via dnr.maryland.gov. Full 50-state comparison: Dog Rules in America’s State Parks.
