Access Points Technically, the D&R canal starts near Bull's Island (now a state campground) in Raven Rock where it connects to the Delaware River; the trail north of the Bull's Island inlet is a rail trail built on the former rail bed of the Pennsylvania Railroad Belvidere Division; the surface is crushed stone.

Bordered by Route 29 on the east and the Delaware River on the west, there are few access points along its length.

Competition from federally funded highways and automobiles caused passenger service to end by 1960.

The government-created entity Conrail abandoned portions of the line between Trenton and Milford in the late 1970s.

Much of the feeder canal path is actually a rail-trail; the only official towpath segments are in Trenton and Lambertville.
