From late October until February, over 25,000 black-and-orange monarchs make their winter home here. Forming dense clusters in the tops of eucalyptus trees, they might easily be mistaken for leaves. Between 10am and 4pm during the roosting season, volunteers can tell you all about the insects’ incredible journey, which outlasts any single generation of butterflies. Look for a gravel parking pull-out on the ocean side of Pacific Blvd (Hwy 1), just south of Pismo State Beach’s North Beach Campground.
