PATAPSCO HERITAGE TRAIL
The Patapsco Heritage Trail is envisioned to be an on/off road trail that connects Ellicott City/Catonsville to the BWI Regional Trail System.  The BWI regional trail system in turn connects BWI to the Annapolis area where the regional trail connects to two national trails - the East Coast Greenway running North-South from Calais, Maine to the Florida Keys and the American Discovery Trail running East-West from Lewes, Delaware to Point Reyes in California.

The on-road section north of the Patapsco State Park follows along the Patapsco from Ellicott City to Illchester where it enters the Park. The Trail follows the Grist Mill Trail and its recently completed extension within the Park. South of the Park, the Trail follows the bike route signs on back country roads to the BWI Trail. The portion of the Trail within the Park is the only portion which is presently suitable for young or inexperienced bicycle riders.
