Take wing on a nature hike to view the cliffs and caves of Castle Rock—nesting site of the Peregrine Falcon, the fastest animal on Earth! 

By the mid 1950's Peregrine Falcons disappeared from the steep cliffs of Mount Diablo, victims of DDT. Re-introduced to the area in 1989, they have done well, but now face record numbers of visitors to our wild lands, especially in spring and early summer when they urgently need space and privacy to raise their chicks. We'll view the cliffs from far below in Pine Canyon with two leaders of the MDIA Peregrine Team, Rosita Harvey and Jenn Roe.

Our route follows the historic Stage Road, then up the Little Yosemite Trail, and finally past the enigmatic China Wall. Along the way, we'll enjoy late spring wildflowers.

This is a moderate hike of about 5 miles with several hundred feet in elevation change. There is an option for an easier 2-mile hike over mostly level terrain. Rain cancels.
