This beach, with its famous natural bridge, is an excellent vantage point for viewing shore birds, migrating whales, and seals and otters playing offshore. Further along the beach, tidepools offer a glimpse of life beneath the sea. Low tides reveal sea stars, crabs, sea anemones, and other colorful ocean life. The park also includes a large area of coastal scrub meadows, with bright native wildflowers in the spring. Moore Creek flows down to the ocean through these meadows, forming a wetlands in the sand.

Monarch Butterfly Natural Preserve:
The park's Monarch Grove provides a temporary home for over 100,000 Monarchs each winter. From mid-October through the end of February, the Monarchs form a "city in the trees." The areas mild ocean air and eucalyptus grove provide a safe roost until spring. In the spring and summer, the butterflies live in the valley regions west of the Rocky Mountains where milkweed, the only plant a Monarch caterpillar eats, is plentiful.
The Monarch Grove has been declared a Natural Preserve, thus protecting the Monarchs and their winter habitat from human encroachment or harm. This is the only State Monarch Preserve in California. Access to the preserve area is limited to a handicap accessible boardwalk and observation area.
Monarchs begin arriving in October and most are gone by the first week of March. The grove contains eucalyptus trees which are located in a canyon, providing the Monarch needed shelter from the wind. These winter flowering trees are also a convenient food source for the butterfly. On chilly days when the temperature drops below 60 degrees, the butterflies cluster together in the eucalyptus trees for warmth.
The park maintains a demonstration milkweed patch where visitors may view Monarch eggs, caterpillars and chrysalides. For about half a year, milkweed is the Monarch's home, super market and maternity ward. The Monarch larva eats only the milkweed plant.
Docent-led butterfly, tidepool and nature trail tours are available. Large groups should reserve beach use and tours by phone at least 2 weeks in advance. Special event reservations should be made at least 1 month in advance.
Visitors can view the over-wintering Monarchs by walking down the park's wheelchair and stroller-accessible boardwalk to an observation deck in the eucalyptus grove.
