About This Event

Join us for this unique opportunity to discover the extraordinary creatures who come out when the sun goes down.

As night falls, Grassroots Ecology naturalists will guide you around Arastradero Preserve's grassy hills and oak woodlands. We'll keep an eye out for critters such as bats, owls, spiders, glow-in-the dark scorpions and millipedes, and more!

Attendees should expect to walk 2.5-3 miles on dirt and gravel trails with limited visibility. Don’t forget your flashlight or headlamp (red/UV light recommended)!

Visit Grassroots Ecology’s Pearson-Arastradero Preserve webpage to learn more about the ecosystem and accessibility considerations.

Grassroots Ecology encourages people from all identities and backgrounds to participate in our programs. Many of our programs are outdoors and involve moving and working in a variety of landscapes. If you have accessibility concerns (e.g. allergies, limited mobility, learning differences), our projects are flexible and we are happy to work with you. Please reach out to the workday facilitator so we can prepare for your participation.
