Outdoor thrillseekers have probably never experienced anything like Delaware's new Go Ape Treetop Adventure Course, a tarzan-esque climbing challenge that's the first of its kind in the region. The course at Lums Pond State Park features a series of zip lines, Tarzan swings, rope ladders, bridges, swings, and trapezes, which typically take 2-3 hours to complete, and are suited to all skill levels.
