Every fall in the Bay Area, male tarantulas take advantage of cooler temperatures and venture out of their dens to seek out a mate. These fuzzy arachnids might give some people the creeps, but they’re actually completely harmless. Some locals and visitors steer clear of certain Tri-Valley parks during tarantula mating season, while others seek out these eight-legged creatures.
Here’s everything you need to know about tarantula mating season in the Tri-Valley, including when and where to find them.
You can usually expect to see tarantulas out and about starting the end of August and spanning through early November. Mating season, and tarantula sightings, typically peak around mid-October.
Tarantulas can be found in multiple outdoor recreation areas in the Tri-Valley, but they’re most prominent at Mount Diablo State Park, Del Valle Regional Park, and Sunol Regional Wilderness. Once you’ve arrived, you’re likely to see them crawling on roads, trails, trees and other vegetation in plain sight.
While visitors are usually able to spot tarantulas on roads and trails without help, multiple organizations host naturalist-led tarantula hikes in our parks to help shed additional light on these interesting arachnids. The East Bay Regional Park District hosts tarantula treks in both Del Valle Regional Park and Sunol Regional Wilderness. Save Mount Diablo and the Mount Diablo Interpretive Association facilitate hikes at Mount Diablo State Park.
