Thousands of monarch butterflies have filled the eucalyptus trees at the Pismo State Beach Monarch Butterfly Grove.
The monarchs start arriving at the grove in late October and spend the winter there before leaving in February.
An estimated 30,000 monarchs were clustered at the grove as of Jan. 2, according to www.monarchbutterfly.org, a website funded by the Pismo Beach Conference & Visitors Bureau.
The grove is located on the west side of Highway 1, just south of the North Beach Campground in Pismo Beach. The grove is staffed daily from 10 a.m. to 4 p.m., with docent programs at 11 a.m. and 2 p.m.
