Capital Crescent Trail. Suited for bicyclists, walkers, rollerbladers, and strollers, this paved trail stretches along the old Georgetown Branch, a B&O Railroad line that was completed in 1910 and was in operation until 1985. The 7.5-mile route's first leg runs from Georgetown near Key Bridge to central Bethesda at Bethesda and Woodmont avenues. At Bethesda and Woodmont the trail heads through a well-lighted tunnel near the heart of Bethesda's lively business area and continues into Silver Spring. The 3.5-mile stretch from Bethesda to Silver Spring is gravel. The Georgetown Branch Trail, as this section is officially named, connects with the Rock Creek Trail, which goes to Rockville in the north and Memorial Bridge past the Washington Monument in the south. On weekends when the weather's nice, all sections of the trails are crowded. Washington, DC. 202/234–4874 Capital Crescent Coalition. www.cctrail.org.
