Runner Notes

A fairly steep trail with many rocks and roots to negotiate - place your feet carefully.

Description

Gregory Canyon goes west past the junction of the Saddle Rock Trail, crosses a ridge with spectacular outcrops and views. It then climbs to a saddle and drops into a drainage to end at a dirt road leading up to Realization Point.

Flora & Fauna

Black bears and mountain lions inhabit this area. Many other wildlife species are common including birds of prey, mule deer and coyotes. White-tailed and mule deer are common. Red-tailed hawks, foxes and coyotes are sometimes seen.

Hop across rocks here to cross the stream. There is a lot of flood debris scattered around here.

As of 2015, the stream crossing is still washed out from the 2013 flood.
