For anyone vacationing at Rehoboth Beach, Delaware, I wanted to make a recommendation. Most people who come to Rehoboth come for the boardwalk, beach, and outlets, but also check out the Junction and Breakwater Trail (see
http://www.destateparks.com/Activities/trails/J&B....
It's a beautiful and easy trail for walking, running, and riding (no rollerblades here, though. It's a crushed-stone trail).
Today I ran from Holland Glade to Wolfe Neck. It's beautiful, winding, gravel-trail. At the trailhead are cornfields and open glades of purple, golden, and green grass, and from here the trail winds through copses of oak, sassafras, hickory, pine, and holly (the state tree) and along open cornfields. In the first copse, I spotted a doe and two fawns, and other times I've run this trail at dawn or dusk I've seen deer on the edge of the wooded areas. Closer to the Wolfe Neck trailhead, the trail passes over a long, but low bridge that passes over a marsh and Holland Glade, a beautiful stream running through the wetlands. I turned around at this point for my 30 minute run, but the trail continues. Anyone who comes to Rehoboth would love to run or ride this trail.
As a Delaware native myself (now living in St. Louis and vacationing at my parents' house), I love to brag about what we have to offer.
PS: For paddlers, Henlopen State Park in Lewes has rentals for bay and ocean kayaks.
