This route was planned by komoot.
The trail is located in Patapsco Valley State Park, Maryland. It provides a crucial link between the Hollofield Campground and historic Ellicott City. You can access it from either the campground or from Ellicott City, offering flexibility for your hike.
While the trail is rated as 'easy' overall by komoot, some sections are described as having 'Blue difficulty' and a 'Moderate' physical rating due to challenging segments, including a high-exposure area. Beginners should be prepared for varied terrain and some elevation changes.
The trail features varied terrain, including natural surfaces typical of a state park. A notable segment was professionally built using a mini excavator, particularly above the Union Dam Tunnel, to navigate difficult terrain and avoid an active railroad line. Expect some challenging sections.
The trail can be enjoyed year-round, but spring and fall offer pleasant temperatures and beautiful scenery. Summer can be warm and humid, while winter hiking is possible but may involve colder temperatures and potentially icy conditions on some segments.
Yes, dogs are permitted on the trail, but they must be kept on a leash at all times. Please remember to pack out any waste.
As the trail is located within Patapsco Valley State Park, standard Maryland State Park entrance fees may apply, especially if you are driving in. It's advisable to check the official Patapsco Valley State Park website for current fee schedules and any specific permit requirements.
Yes, the OEC and Campground Connector Trail is designed for connectivity. It links the Hollofield Campground to historic Ellicott City and also provides connections to other trails within Patapsco Valley State Park. Specifically, the route also passes through sections of the OEC Connector, Peaceful Pond Trail, Patapsco Howard County Thru Trail, Patapsco Traverse (south hiking), and Patapsco Traverse (south mtb).
A significant feature is the innovative construction above the Union Dam Tunnel, which allows hikers to bypass an active CSX railroad line safely. The trail's primary highlight is its role in connecting park guests to historic Ellicott City, offering opportunities to explore local shops and dining.
Given its 'easy' komoot rating and the option to connect to amenities in Ellicott City, it can be suitable for families. However, be aware of the 'Moderate' physical rating and some challenging, high-exposure segments mentioned in the trail research. Supervise children closely, especially in these areas.
One of the trail's main benefits is its direct connection to historic Ellicott City. This means you can hike from the campground directly into town to access a variety of amenities, including cafes, restaurants, shops, and other local businesses.
The OEC and Campground Connector Trail primarily functions as a point-to-point connector between the Hollofield Campground and Ellicott City. However, its connections to other trails within Patapsco Valley State Park allow for the creation of larger loop routes if desired.
