Monarch butterflies have arrived: Three best California monarch sanctuaries


California is home to monarch butterfly western migration.

Starting in late summer and fall, monarch butterflies west of the Rocky Mountains fly down to coast of California, where they spend the winter months, November to February.

In spring, western monarch butterflies leave the coast, and fly inland through California, Oregon, Nevada, Idaho, Rocky Mountain foothills, migrating back to area where they originated, as far north as Canada.

In winter, monarch butterflies need a warm environment (no frost), protection from wind and rain, and source of water and nectar. Overwintering monarch butterflies semi-hibernate, clustering together for warmth and safety from predators, saving their energy until spring arrives.

Three best monarch butterfly sanctuaries are in central coast California – Pismo Beach, Pacific Grove (Monterey), and Santa Cruz.

Each sanctuary provides what monarch butterflies need – sheltered woodlands (eucalyptus, cypress, pines trees), source of water (coastal fog or pond), food (nectar) from flowering plants and trees.

Tip: In the morning hours when its cold, butterflies stay clustered in the trees; when it warms up they open wings, sun themselves on branches and fly around.

Peak months to see monarch butterflies is late November to early January.

Monarch butterfly sanctuaries are fun multi-generational activity for families – walkways or boardwalks are okay for strollers and easy for grandparents.
