30,000 butterflies at one of the largest overwintering sites for the Western Monarch

The Pismo Beach Monarch Butterfly Grove shelters Monarch butterflies from freezing temperatures during the winter. This grove is one of only a few sites that count over 10,000 butterflies annually. This location is estimated to contain around 30,000 butterflies each winter and is the largest wintering area on the west coast. Once temperatures begin to warm, the monarchs will begin their migration north again. Many are still here now, and it is incredible to see so many Monarchs flying around in one place.
