China Beach is a quasi hidden jewel in the Sea Cliff neighborhood of San Francisco. It's a beautiful place to have an intimate beach wedding.
A neighborhood beach, China Beach hasn't been discovered by many, so it's possible to get a bit of seclusion for your ceremony. Note: this beach has a fairly steep access (your choice of stairs or a winding path--about a 3-minute walk) so it's not for those with breathing or mobility issues.
