The South Boundary Trail loses most of its elevation in the last 5 miles, with the steepest of those being the last 3 miles called the "El Nogal" section. For those less experienced riders — or if you've had any trouble with what you rode up to the "log drop" at the Ojitos trail — we recommend taking the Ojitos descent instead of the El Nogal technical downhill descent. Ask your shuttle driver for details.
