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. Let’s find out if this is the gruesome truth or just arachnophobia!

During this nature walk through Mitchell Canyon, you’ll dispel any malicious rumors you might have heard about Mount Diablo’s misunderstood arachnids. As the sun sets, you’ll be on the lookout for another one of Mount Diablo arachnids – scorpions!
