Join Peninsula Open Space Trust (POST) for a beautiful, family-friendly, and fun-filled fall morning at Calero County Park! Celebrate the season by getting outside and experiencing the natural beauty of one of Santa Clara County’s most diverse regional parks. Knowledgeable staff members and POST volunteers will lead a variety of age-appropriate hikes, and will also have an assortment of interactive activities to participate in.

Our main activity will be a Halloween Costume Hike! Participants of all ages are encouraged to come dressed up and ready to enjoy some great goodies that we will be passing out at the end of the hike.

All minors must be accompanied by an adult, parent or guardian.

Schedule of Events:

9:30 AM – 10:15 AM: Registration
(Pull up your QR code from your Eventbrite Ticket) Arrive on time so you don’t miss any of the fun!

10:30 AM – 11:30 AM: Costumed Hikes
POST Staff & Volunteers will lead two versions of a hike; one shorter hike (~1.0 miles) for younger children and a longer hike route (~2.6 miles) for those who want to get some more steps in. The longer hike does feature some steep inclines and declines, so please consider your ability to complete the hike! Both hikes will feature a goodie bag at the end of the hike.

This event is part of POST’s community event series. These events are open to the general public as well as POST donors, and we hope you will join us! We also curate a separate series of private events for our donor community. Find out more about how you can support POST here:

About Calero County Park:

Once part of the Pueblo lands of San Jose and Rancho San Vincente land grant, this approximate 4,471-acre park is nestled in the eastern foothills of the Santa Cruz Mountains. Two distinct areas define this park: the reservoir, which offers a host of water-oriented recreational activities, and the adjoining “back country” which reveals to the visitor California Oak woodland, chaparral, riparian plant communities, and associated wildlife habitats. During the months of March, April and May the “backcountry” offers a spectacular display of wildflowers. To learn more, visit this website!
