Viewing Tips

  1. Bring Binoculars: Essential for getting close-up views of whales, seals, and butterflies.
  2. Plan Ahead: Popular viewing sites like Año Nuevo State Park often require advanced reservations for guided tours during the winter Elephant Seal season.
  3. Respect Wildlife: Bay Area animals are protected. Maintain a safe distance, especially from seals and pups, and never feed the wildlife.
  4. Dress in Layers: Weather along the coast and bay is notoriously changeable. Be prepared for wind and cold, especially during winter whale watching boat trips.
