All Discover Diablo hikes are subject to, and will honor, all applicable COVID-19–related restrictions in place for our area.

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 rattlesnake’s, and delivering a bite generally considered fatal.” Yeesh. Is this the gruesome truth or just arachnophobia?

Join us for a nature walk through Mitchell Canyon and we will dispel any malicious rumors you might have heard about Mount Diablo’s misunderstood eight-legged creatures.

Be sure to bring plenty of water and a snack, and dress in layers. Sturdy shoes or hiking boots are recommended. Heavy rain cancels.

Due to COVID-19, we are limiting the hike to 8 participants. All participants must bring a mask and stay 6ft apart. Hand sanitizer will be available at the hike.

Participants will also be required to accept our COVID-19 Protocol (available during registration).
