La Cumbre was home to the UCSB golf team when I played there 40+ years ago, sounds like it still is.
The kikuyu infestation is the only real problem at La Cumbre except for changes over the years which irritate the hell out of Geoff Shackleford (also a UCSB golfer before he transferred to Pepperdine), such as the filling in of the barranca in front of current #8, originally #16.
There is an ongoing problem with erosion and landslides behind #8, and a major retaining wall to be built soon. Old #17, the NLE par 3 which followed original #16, slid down the hill many years ago.
The kikuyu is so velcro-like that it is almost impossible to play any ground game shots at La Cumbre, every shot must be pitched onto the greens, which are very fast and great green surfaces. They are way past the point of eliminating the pest grass so get used to it.
The course has some terrific holes. #1 is a straight away 420 from an elevated tee. #2 goes back to clubhouse with a green almost as far above the fairway as #1 tee, and features a two tier demonic green. Do NOT be in back if the pin is in front!
#4 is a short dog leg left with a monster tree in the corner. The best play is away from the tree about 225, that opens up the uphill pitch.
#12 is a stout par 5 cape hole. #13 is the famous par 3 across the water 220 yards, Redan-ish except for a bunker in the way. Somehow the club has mucked this up by building an alternate shot par 3 on an island green off to the left. I don't really understand how anyone could have reasonably done this, given the fame and quality of the original.
#14 is a very solid dog leg left, 425, continuing around the lake which is in play on 12, 13, and 14 counterclockwise. Uphill midiron approach to a green that sits unbunkered on top of the hill between two large trees.
#18 is an excellent finisher, 410 yards dogleg right, downhill drive, uphill approach. The clubhouse is quite a ways above the green, but there's a rope tow to assist the hike up.
Have a great day, I am a big fan of LaCumbre and enjoy it very much.
