5:30 - 8:30 PM


We will assemble near the Mitchell Canyon Visitor Center.


A scientist exploring California in the 1860s described Mount Diablo's tarantulas as "attaining the size of a half-grown mouse, possessing fangs the size of a rattlesnakes, and delivering a bite generally considered fatal." Yeesh! Is this the gruesome truth or just arachnophobia?

Join us for a talk and nature hike up Mitchell Canyon and we will dispel any malicious rumors you might have heard about Mount Diablo’s famous spiders. You'll also have a chance to get close up and personal with a tarantula named Scarlet O'Harry, the real-life (not just Facebook friend) of hike leader Liz Watson.

This is an easy hike of about 2 miles round trip with a 400-foot elevation gain. Bring liquids, snacks, and a flashlight. Dress in layers and wear good hiking shoes. Bring poles if you normally use them. Restrooms and water are available near the trailhead. Rain cancels.
