In my last post, I wrote that one of Malibu's best-kept secrets is that Carbon and the other public-private beaches are open 24 hours--that's true--and that the 17 access gates, while they close at sunset, remain unlocked from the beach side.
Which turns out to be true with one exception--the Carbon Beach gate at 22126 PCH. To leave Carbon after dark, you have to exit a mile up the coast at the other Carbon accessway at 22706 PCH. (Keep an eye on the tide, though, since the high tide sometimes covers part of that mile.)
I think that's the best-kept secret in Malibu.
Enjoy the beach--and watch out for the paparazzi.
