June 25, 2025, Califon Train Station

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.

There are abandoned railroad ruins along the sides of the road. There are even still rails on the ground in spots overgrown with grasses and weeds.

The Columbia Trail is a gorgeous Greenway along the South Branch Raritan River from this trail head to High Bridge, almost 15.5 miles to the south. Absolutely incredible views all the way through, autumn could be the best time to enjoy the trail. This parking at the northern trailhead isn't very big, but a couple of cars can fit in it.

This stunning lake features a unique rock wall waterfall and is surrounded by lush trees. The sights are even more amazing in springtime when the leaves start to change colors.
