Event description


Find out if you have arachnophobia or fall in love with spiders as naturalist and hike leader Ken Lavin introduces you to the gentle giants of Mount Diablo. Early fall is a busy time for local tarantulas as they look for love on the mountain. Join us for a moderately paced four-mile hike with moderate elevation change to dispel myths about tarantulas and observe them in nature. Be sure to bring plenty of water, a snack, and dress in layers. Sturdy shoes or hiking boots recommended. Heavy rain cancels.

Are there ID or minimum age requirements to enter the event?

Anyone under the age of 18 will need to be accompanied by a parent or guardian.

Do I have to bring my printed ticket to the event?

No. On the hike day, we will have a roster with your registration information on it. Please make sure to check in with the hike leader.

Yes. If you would like to change anything, please contact Denise Castro at

We recommend long pants, sunscreen, and a hat. Dress in layers. Running shoes are OK. For strenuous hikes, we suggest sturdy hiking boots.
