Crossing Over the C&O Canal

Highlight • Bridge

It's just a shame that cycling is only allowed on the paved road. The many earthy trails to the right and left of the road are very tempting for a mountain biker. Unfortunately explicitly forbidden.

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.
