The B&A Trail Park encompasses 112 acres andÂ stretches 13.3 miles from Jonas Green Park in Annapolis to Dorsey Road in Glen Burnie, passing throughÂ Arnold,Â Severna Park,Â Millersville, andÂ Pasadena. The trail follows the route of theÂ Baltimore & Annapolis Railroad from which it derives its name. The trail opened in 1990 as the second rail trail in the state.
In 1999, the B&A Trail Park was named a National Millennium Trail. The B&A Trail is also a designated component of the East Coast Greenways, a route connecting major cities between Maine and Florida, while the southern portion of the corridor is a segment of the American Discovery Trail, a national trail extending from Delaware to California.
The Earleigh Heights Ranger Station is located in Severna Park with parking available on the premises. A gazebo, horticultural gardens and park benches are found at the Hatton-Regester Green property in Severna Park. 80 flowerbeds, all tended by volunteers, grace the park grounds.
The trail includes a Planet Walk sponsored byÂ NASA. The Planet Walk is a linear museum with educational displays for eachÂ planet and theÂ sun. The central sculpture, Spectrum, is a 26 foot tall sculpture topped with 9 rings.
At the north end of the trail, the B&A Trail connects to theÂ BWI Airport Trail for another 11 miles of running. At the south end of the trail it is only a short 2 miles to the Naval Academy and Annapolis.
Since 1998, the trail has hosted the popular B&A Trail Marathon and Half Marathon each Spring, which draws approximately 225 marathoners and 650 half marathoners.
