Natural Bridges State Beach
Natural Bridges State Beach is world-renowned for its yearly migration of monarch butterflies. Visitors can see thousands during the butterflies’ peak season. The best time to see monarchs in the park is usually from mid-October to late January.
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 and grasslands, with bright native wildflowers in the spring. Moore Creek flows through the park, forming freshwater wetlands and a salt marsh before it reaches the sea.
Take Swift Street west from Highway 1, or follow West Cliff Drive north along the bluffs until it ends at Natural Bridges.

Natural Bridges State Beach is named for three naturally occurring arches that were once part of a large cliff that jutted out into the sea. The bridges formed as wave power eroded the mudstone, deepening depressions in the cliff that grew until the rock formed a cave, and eventually, a bridge.
Of the three original arches, only the middle one remains. The outermost arch fell during the early 20th century, and the inner arch collapsed during the 1980 storm.
