Patapsco Valley State Park – Daniels Area

2090 Daniels Road, Ellicott City, MD 21043
(410) 461-5005

Patapsco Valley State Park is huge, extending along 32 miles of the Patapsco River, spanning four counties, and encompassing 16,043 acres and eight separate recreational areas. Patapsco Valley State Park, originally called the Patapsco Forest Reserve, was the very first state park established in Maryland; the nucleus of the park dates back to 1907, with the donation of 43 acres of land in Catonsville by the philanthropist John Mark Glenn. Other portions of Patapsco Valley State Park in this Birder’s Guide are Henryton, which is nearby in Howard County, and the McKeldin Area in Carroll County.

The Daniels area of Patapsco Valley State Park is in northeastern Howard County; the Patapsco River here forms the boundary with Baltimore County, and part of the Daniels area is on the north side of the river, in Baltimore County. This description covers only the Howard County portion of Daniels, on the south side of the river and comprising roughly 400 acres.

This largely undeveloped area of Patapsco Valley State Park was once the site of a bustling mill town, and reminders of the past are scattered along the trails here. Most of the Daniels area is wooded floodplain forest along the Patapsco River or upland deciduous forest on steep hillsides. There is access to a stream valley with mature trees adjacent to the paved parking area on Daniels Road, and additional small stream valleys upriver. A limited amount of open lawn and brushy area around the Daniels Dam and historic church provides diversity.

Access to the Daniels area is via Daniels Road, which winds northward from Old Frederick Road and descends into the Patapsco River Valley, before coming to a dead end on the south shore of the river. There is no river crossing. There are several shoulder parking areas along Daniels Road and two parking lots at the river. There are active businesses at the end of the road and an historic church.

The main trail heading upstream (to the west) along the river is broad and shaded and is a pleasant walk in all seasons.  The trail is orange-blazed and is shown on the DNR trail map at the link at left. The Daniels Dam creates a two-mile slack water stretch upstream.

After parking your car, walk south along Daniels Road (going back the way you came when driving in the car), birding along the way. There will be activity here earlier in the morning than on the main trail.

To walk the main trail, enter the gated gravel road heading west from Daniels Road just a few hundred feet south of the small parking lot. Follow the gravel road upstream (i.e., west). The road often has muddy areas which are usually easily skirted. The road at first runs along the water, but soon the floodplain widens, and a dirt path leads off to the right along the water. The trees at the water’s edge along this path may have the most activity in the morning sun. The riverside path rejoins the road and becomes the main trail about one-half mile west of Daniels Road. A spur that veers to the left at this point leads to abandoned buildings. Beyond a gate blocking vehicles, the trail narrows and continues along the river. It is generally level and dry, but there are occasional permanently muddy spots which must be bypassed where water seeps from the hillside. The path runs west for several miles within sight of the river, terminating at the Davis railroad tunnel. Most birders bird the main trail as far as desired or as time permits and then return along the river. If you took the riverside path on the way upstream before reaching the gate, try the gravel road on the way back, as the steep hillside can give good views up into the interior forest.

There are additional trails and spurs that can be explored in the Daniels area. Several of the trails are loops and there are numerous confusing intersections, so we recommend using a compass and/or GPS device and a state park trail map. MD DNR’s geo-locator-enabled trail map can be downloaded and printed from the link at left, or better yet, download the DNR trail map to an app on your smart phone and use it to follow the trail in real time as you hike.

Alternatively you can use DNR’s free Interactive Trail Atlas or free Maryland Interactive Recreation Atlas, both of which are smart-phone-enabled; download these two apps from Also see the Howard County Bird Club’s online guide Birding Howard County, which features a simplified trail map at
