Pro Tips
- 1.Arrive at low tide for the best tide pooling experiences,check tide charts before your visit to time it perfectly for discovering sea stars, anemones, and hermit crabs
- 2.Bring layers and windbreakers even on sunny days, as coastal fog and wind can roll in quickly, especially in the afternoon
- 3.Pack a complete beach kit including sand toys, kites, and a picnic blanket since there are limited amenities and no food vendors on-site
- 4.The parking lot fills up on warm weekend afternoons, so aim for morning visits or weekdays for a more peaceful experience

Best Time to Visit
Visit on weekday mornings or early afternoons for the most peaceful experience and better parking availability. Spring and fall offer the clearest days for tide pooling and sunset viewing, while summer mornings before the fog rolls in provide the warmest beach conditions for families.
What to Know
Parking is free in the beach lot off Thornton Beach Road. There are no restaurants, restrooms are basic, and no lifeguards are on duty, so pack everything you need and supervise children closely near the water due to strong currents and cold temperatures.
Seasonal Notes
Spring (March-May) offers the best tide pooling and clearest weather. Summer brings fog that typically burns off by afternoon. Winter can be stormy with dramatic waves perfect for watching from a safe distance. December through April is whale migration season, offering potential sightings from the coastal trails.
