Clusters of black, orange and yellow will once again fill the eucalyptus trees in Pismo Beach starting Oct. 27, according to a California state parks news release.
The opening-day celebration is slated for Oct. 27 to welcome back the butterflies to the Pismo State Beach Monarch Butterfly Grove.
The butterflies cluster at the grove from late October to February.
More than 80,000 people visited the butterflies last season, the Pismo Beach Conference & Visitors Bureau reported.
The Pismo Beach colony of monarch butterflies is one of the largest in the nation, hosting an average of 25,000 butterflies over the past five years, according to www.monarchbutterfly.org, a site funded by the visitors bureau.
The opening day event runs from 10:45 a.m. to 2 p.m. at the grove, located on the west side of Highway 1, just south of the North Beach Campground in Pismo Beach. This years event is about an hour longer than last year's butterfly festivities.
The grove is staffed daily from 10 a.m. to 4 p.m., with docent programs at 11 a.m. and 2 p.m.
