  Also known as Loma Alta Falls. It's an easy hike to see parts of it from the fire road. The short path to the base (where most people go to see all of the main drop) is somewhat harder, with much poison oak. You can also see it from the sides, but that involves steep terrain without much of a trail.

  route: Take Lucas Valley Rd west to mile marker 5.07 (about 0.3 mile before the Big Rock. There are turnouts on each side of the road for very temporary stops. I don't recommend trying to get closer to the falls. Among the obstacles are random pieces of old barbed wire.
