New Carrillo Trail Opens on February 19, 2014


The new trail section is .7 miles long and is located east of the damaged trail section.

The new Carrillo Trail is 0.7 miles long and replaces approximately 0.9 miles of the heavily damaged Carrillo Trail section between the Douglas Spring Trail and Three Tank.

This change was necessary to prevent further damage along the old Carrillo route which suffered from deep rutting as a result of water runoff being caught in the trail and cutting down the trail.

The new trail gains approximately 70 feet in elevation, as opposed to the 15% grade in some areas of the previous trail, creating a safer and more easily maintainable trail for hikers and horses.

The old section of the Carrillo Trail will be closed and rehabilitated to prevent further damage to the area once the new section is open.
Carrillo before
The old Carrillo Trail became a drainage for water in wet weather due to its steep slope and lack of switchbacks and waterbars to drain the water away. 

These deep ruts were difficult to hike in and dangerous for horses.
