Pond Day at Martin Griffin Preserve

Saturday, May 25 @ 10:00 am - 4:00 pm

| $20

Newts, and damselfly larvae, and scuds, oh my! Come join us on May 25th for our ever-popular Pond Day where we get up close and personal with the many critters who make our ponds home. Join our volunteer Nature Guides in scooping up some goodies (avoid the muck and the duck weed!) and examining pond life with magnifying boxes and under microscopes.

As every Saturday, we’ll have ample opportunity for nature exploration! Join our volunteer Nature Guides and grab a pair of binoculars or peer in the scopes to watch osprey dive for fish and eagles disrupt the waterbirds over the Bolinas Lagoon. Come out to our kids’ tables to do activities related to the sights, sounds, and smells of May at Martin Griffin Preserve. Learn about the wonders of nature and hike through redwoods, mixed evergreen forests, coastal scrub, and enjoy sweeping vistas of the Bolinas Lagoon and Pacific Coast. No reservation necessary — please join us! Bring your family and friends!
