Dalecarlia Tunnel on the Capital Crescent Trail

Highlight (Segment) • Structure

Relatively wide path with no crossings and it's all downhill so very easy. But, it can be pretty crowded.

Key Bridge Boathouse

Highlight • Rest Area

Boathouse where canoes, kayaks and stand-up paddle boards can be rented. Great way to explore the Potomac shoreline up and down stream.

Francis Scott Key Bridge

Highlight • Bridge

This is a paved path across the bridge with metal railings separating pedestrians/cyclists from vehicular traffic. It feels safe but it can be a little loud. The views are beautiful.
