Summer Celebration at Martin Griffin Preserve
July 27th is the last day of our summer season at Martin Griffin Preserve -- time to celebrate! Enjoy the late-season flowers, changing sounds and smells, and warmer days with guided hikes at 11am and 2pm offered by our volunteer Nature Guides, with summer celebration activities and crafts throughout the day.

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. Grab a net and scoop a newt at our freshwater ponds. Come out to our kids’ tables to do activities related to the sights, sounds, and smells of June at Martin Griffin Preserve! No reservation necessary -- please join us!
