Signed Monarch Trail begins near the park's small interpretive center. Soon the trail splits; the leftward fork leads to a monarch observation platform. Sometimes on cold mornings, the butterflies look like small, brown, fluttering leaves. As the sun warms the tropical insects, the "leaves" come to life bobbing and darting. As many as 200,000 monarchs cluster in the state park on a "good" butterfly year. The other branch of the trail is a self-guided nature trail. It ends in a grove of Monterey pine.
Take Swift Avenue west from Highway 1, or follow West Cliff Drive north along the in-town bluffs until it ends at Natural Bridges.
