Possibly the most wonderous of all natural wonders in Santa Barbara, California. The Coronado Butterfly Preserve is a place where - from late October through early March - monarch butterflies migrate to spend the winter. They hang in clumps and clusters from the branches of the eucalyptus trees, often hundreds at a time. Free to the public (there is a donation box at the entrance), the Coronado Butterfly Preserve open every day from sunrise to sunset. Even in the off season, the preserve is a beautiful place to visit, home to numerous birds and wildlife, Devereux Creek, trails, open area and outdoor gathering areas and classroom.
