This trail is currently closed due to significant slide damage and high-risk hike-a-bike conditions.
The Santa Cruz trail heads south from Alexander saddle. The trail begins by heading down through a series of steep meadows. There is little to obscure your view but the exposure is quite significant. After a few miles, the trail changes character and encounters a couple rocky technical sections culminating in a series of shale slides.
Once the slides are navigated, the trail winds and twists deeper into the canyon. It is easy to miss the junction on the left with the 19 Oaks Train. As the angle eases the fun continues. A few rocky sections, and some tread balanced precariously on the canyon wall, end suddenly as the Big Pine/Buckhorn road is met.
