Patuxent River State Park – Annapolis Rock Road Area

17261 Annapolis Rock Road, Woodbine, MD 21797
(301) 924-2127 

Patuxent River State Park is comprised of 6,700 acres of natural areas and farmlands, located in Howard and Montgomery Counties along the upper 12 miles of the Patuxent River. The Patuxent is the longest river contained entirely within Maryland, and along its length, changes from a sleepy, slow-moving stream to a wide tidal estuary that empties into the Chesapeake Bay near the southernmost point of Maryland’s Western Shore.

Note: Do not confuse Patuxent River State Park with Patuxent River Park – Jug Bay and Patuxent River Park – Mount Calvert; the latter two are part of a county-owned series of parks in Prince George’s County on the tidal portion of the river.

Patuxent River State Park, following the river valley, is long and narrow, with its long axis oriented approximately northwest to southeast. A portion of Patuxent River State Park is a designated State Wildlands Area. There are numerous parking areas and access points, as shown on the official park trail map at the link at left. Or download a handy table that shows the locations of the various parking areas with GPS coordinates, street addresses, and links to Google Map screens.

This description is for the Annapolis Rock Road access in Howard County on the north side of the river, where Annapolis Rock Road runs roughly east-west, between Hipsley Mill Road and Woodbine Road/MD Route 94. Note that the trails at the Annapolis Rock Road area connect with those at the Hipsley Mill Road Area, covered separately in this Birder’s Guide.

The Annapolis Rock Road area of Patuxent River State Park is about 450 acres with extensive pine plantings and deciduous woods, scrub and second-growth, upland and floodplain, cultivated fields, streams, a pond, and a beaver-created wetland.

The main parking area on the south side of Annapolis Rock Road is marked by a small sign across from the entrance. Designed to accommodate horse trailers, the parking area is entered through a metal gate which is usually closed, but not locked. The deeply rutted lane leading to the parking area can be difficult for a car with low clearance to negotiate, especially in wet, snowy, or icy weather. The main parking area is in a large, circular, grassy (sometimes muddy) area.

From the main parking area, an extensive network of wide and easily followed horse trails (also used by hikers) fans out through patches of planted pines, along old farm fields, and through young deciduous woods. Trails are generally dry except after heavy rains or where they drop down to cross small streams. Consult the official DNR trail map at the link at left, as well as the detailed trail map also linked at left.

Patuxent River State Park has many unmarked, casual trails that have been created by trail users and wildlife over the years. These trails are not maintained by park staff and should be used at your own risk. Plans are underway to develop an official trail system that will replace the network of casual trails. Call the Park Ranger at 443-962-0216 if you have issues or would like to report hazards.

We recommend using a compass and/or GPS device or a smart phone GPS app. A trail map from the MD Interactive Trail Atlas can be downloaded and printed from the link below. Better yet, access the trail map directly from the free Interactive Trail Atlas or Maryland Interactive Recreation Atlas, both of which are smart-phone-enabled and geo-locator enabled; download these two apps from https://dnr.maryland.gov/Pages/DNR_TrailMaps.aspx.

There are also several roadside pull-offs in the vicinity, and these are handy for roadside birding; see the map and descriptions provided by the Howard County Bird Club at https://howardbirds.website/birding-hoco/site-guide-annapolis-rock-directions.pdf.

In winter, there may be bird feeders behind the MD DNR Forestry & Inland Fisheries building at #17400 Annapolis Rock Road (north side of road), and you can stop in to check the feeders in colder months.

Birdlife:

Over 160 species have been reported on eBird for the Annapolis Rock Road area of Patuxent River State Park.

The extensive pine plantings regularly produce breeding and wintering owls; American Woodcock display here in late winter and early spring; and a variety of warblers(including Cerulean) nest in the floodplain. A total of 27 migrating and nesting warbler species have been reported.

Specialties at Annapolis Rock Road include Wild Turkey, American Woodcock, Barn Owl, Long-eared Owl, Northern Saw-whet Owl, Red-headed Woodpecker, Common Raven, Winter Wren, Gray-cheeked Thrush, and a number of nesting warblers.

To look for feeder birds in winter, go to the MD DNR Forestry & Inland Fisheries building at #17400 Annapolis Rock Road (north side of road), a quarter-mile west of the large gated parking lot. The feeders are behind the building and may offer chances for winter finches and nuthatches.

Wheelchair Access:

The trails at Annapolis Rock are not wheelchair-accessible, but there is fairly good birding at the parking area and at the roadside pull-offs. No restrooms.

Pet Policy: 

Pets are allowed on leash; pick up after your pet and take the pet waste with you when you leave.

Special Designations:

Almost 1,600 acres of Patuxent River State Park in the area of Hipsley Mill Road have been designated as a State Wildlands. Maryland Wildlands are areas of state-owned land or water that have retained their wilderness character or contain rare or vanishing species of plant or animal life or similar features worthy of preservation. These sites are Maryland’s equivalent to the federal Wilderness Preservation System. Passive recreation such as birding and hiking are permitted on State Wildlands.

Special Features:

Local MOS Chapter:

The Howard County Bird Club, a chapter of the Maryland Ornithological Society, holds bird walks at Patuxent River State Park and other sites in the county; such walks are free and open to the public. See the Howard County Bird Club’s calendar for more information.

The Howard County Bird Club has a detailed online guide, “Birding Howard County,” on their website at https://howardbirds.website/birding/birding-howard-county-md/site-guides/.  Edited by Joanne Solem, the online guide replaces an older printed guide, now out-of-print. The website is up-to-date and extremely detailed. Check it out!
