The California coastline varies from top to bottom. Some areas have wide, flat sandy beaches, and others are at the base of rugged cliffs, sometimes accessible, sometimes not. State law says the beaches are for everyone, and must be accessible. People in Malibu and some areas south of San Francisco have rich people who won’t grant access, and lawsuits have been fought long and hard. There is even an app for your phone that tells you where you can access beaches in Malibu, in spite of the fake “No Beach Access” signs put out by land owners on the coast. Funny, but not funny.
Hendry’s Beach (often called “Henry’s Beach”) is a long-time favorite and a popular one in Santa Barbara. At low tide, you can walk a long distance, but if you are not careful about the tides, you could get caught! The ocean is sometimes out enough that a lagoon is formed, and then disappears when the tide comes in.
