Join Greenbelt Alliance for a spirited pre-Halloween walk in Mount Diablo State Park! In this family-friendly walk, we’ll stroll up Mitchell Canyon in search of witches’ broom, devil’s horns, ghost pines, and other scary and not-so-scary signs of the season. But first, we’ll meet the famous 8-legged diva, Scarlett O’Harry (a tarantula), examine the skins and skulls of some of our native Bay Area fauna, and hear the tale of Bully Ingram, a pirate who jumped ship and took up residence in a cave near Mitchell Canyon!
TOTAL DISTANCE: This is an easy hike of two miles round-trip with little elevation change.
