Cosmopolitan Park / Rhett’s Run
Cosmopolitan Park is the diametric opposite of Finger Lakes. There’s little draw for tourists to visit the park other than Rhett’s Run, a fabulous mountain biking loop.
Rhett’s Run (4.8 miles / 473′ gain) is the most popular mountain biking in Columbia. It has a network of tight and twisty turns, rocky sections, and narrow gaps between the trees that make the most of the terrain. It was designed by riders for riders with many reported trail technical features that include: A-Frame, Berm, Bridge, Drop, Jump, Gap Jump, Ladder Bridge, Log Ride, Pump Track, Rock Face, Rock Garden, Roller Coaster, Skinny, Teeter Totter, and Wallride.
I didn’t find all of these on my Rhett’s Run ride, but you can tell by my track on the Columbia bike map that I got a little turned around. The trails get tight and close together in spots, so it wasn’t hard to do. It also didn’t matter in the end. I rode 4.8 miles and enjoyed every twist and turn. I think Rock Bridge might be objectively prettier, but Rhett’s Run was the area’s best ‘pure ride.’
