Believe it or not, this is not lava. This is how the falls look for just a few minutes a day in late February and that's if and only if the timing is right. Provided there's been enough water and the light hits just right, these falls appear to virtually glow. Quite a show, eh?
It's a clothing optional beach, but being in San Francisco weather, most people opt to wear clothes anyway. It's a lovely beach with a really nice view of the Golden Gate Bridge.
