The old train station was built in the late 1800s for the Central Railroad of New Jersey. Today, it serves as a hub for the Califon Historical Society and access point for the Columbia Rail Trail. Supposedly, the name Califon comes from a shortening of "California", since the painter creating the station map didn't leave enough room for the original title.

A packed dirt road takes you along the Raritan River at the sheltered base of the gorge. There are plenty of spots to park as you head in from Readingsburg, but most of the road is closed to vehicle traffic and makes for the perfect bike route. You are right next to the water and can bike along both sides of the gorge.
