  route: From the main entrance to the park, follow the Saratoga Gap Trail to an obvious platform sticking out over the top of the cliff. If you want to view it from the bottom, there are unmarked trails used by rock climbers to the east. The best way to reach the falls on these trails starts quite a ways from the falls. I probably won't be more specific because I don't want too many people using the unofficial trails.

• The size of this set of cascades is impressive, but no single part of it comes close to being as scenic as the well-known falls upstream. at (37.22518, -122.10779):

  The videos show a fair amount of this waterfall, and the static photos show only small parts, due to the trees and due to dangerously steep terrain limiting my choices of where to see it from. My estimate of its size is unreliable because I only saw bits and pieces of it at any one time, separated by much time looking for a somewhat safe route to the next view.
  Beauty: 7.5
  Duration: 365 days after a significant rainfall
  Height 140 feet (broadly defined)
  Height 120 feet
  Biggest vertical drop 15 feet
  route: The terrain is unusually steep, and I'm reluctant to recommend visiting it at all. If you really want to find it, my best guess is that you should start on the unmarked trail used by rock climbers that goes along the ridge to the east. You will lose the remnants of a trail well before reaching the waterfall.

  I'm unsure how much of this to classify as a waterfall. Hard to reach due to the terrain, and insignificant compared to the other falls on the creek.
  Beauty: 6
  Duration: 365 days after a significant rainfall
  Height 30 feet (broadly defined)
  Biggest vertical drop 2 feet
  route: I don't recommend looking for this.

  Hard to reach due to the terrain, and insignificant.
  Beauty: 8
  Duration: 365 days after a significant rainfall
  Height 22 feet (broadly defined)
  Height 18 feet
  Biggest vertical drop 15 feet
  Terrain: woods, little or no trail
  route: My gps reception was very poor in this area, and the routes I took coming and going were unusually steep or covered with dense chaparral. So if you try to find it, expect to be challenged.

Long Ridge Open Space Preserve
Peters Creek

• waterfall at (37.28937, -122.16729):
  Name: Peters Creek Falls

  I wouldn't be surprised if it flows year round. The number of people I saw there suggests it's moderately well known, but the only reference to it that I've been able to find is on a map in Jean Rushmore's book Bay Area Ridge Trail. The start of the trail that I found looks like it only gets a few people, but closer to the creek it seems heavily used, and has signs with rock climbing regulations.
  Beauty: 8.5
  Duration: 90 days after a significant rainfall
  Height 32 feet give or take 6 feet
  Biggest vertical drop 20 feet
  Number of drops 2
  Terrain: unofficial trail, frequently used
  route: From the Grizzly Flat Trailhead, hike 0.4 miles down Peters Creek trail. Turn right onto the Bay Area Ridge Trail. Just before the trail crosses a private paved road (Portola Heights Rd), turn left on an inconspicuous path. The path will follow the creek a half mile downstream to the top of the falls. There are cruder paths that go farther down which look like they are occasionally used by rock climbers.

  This is close enough to the two falls above that they could be considered a single 100+ foot waterfall, but the terrain is steep enough that most people will want to stop near the top of the upper falls.
  Beauty: 7.5
  Duration: 90 days after a significant rainfall
  Height 47 feet give or take 7 feet
  Biggest vertical drop 25 feet
  Number of drops 2
