Tarantula Trek for Families

September 1 @ 6:00 pm - 8:45 pm

Find out if you have arachnophobia or fall in love with spiders as you are introduced to the gentle giants of Mount Diablo.

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? Let’s find out!

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 arachnids. As the sun sets, we’ll be on the lookout for another one of Mount Diablo arachnids – scorpions!

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

Restrooms are available at the parking lot.

***There will be a $6 park entrance fee (exact cash required)
