How to see the Sunset Cliffs sea caves (and why the tide decides everything)
Only at a negative low tide on a calm day. Sunset Cliffs Natural Park in Point Loma hides arches and sea caves below 68 acres of bluffs, but the cliffs are unstable, falls have been fatal, and even at low tide you may wade or swim.
