I saw the Abama Golf Course in Tenerife in October 2005. The Tenerife Open was held that week and was won by John Bickerton. The course was designed by Dave Thomas.
In terms of slope, the course has 790 feet of elevation change. The clubhouse is set in the middle of the property, climbing to the top at the 5th green, then descending on 6, 8, 9, 10 and 11 to the bottom (#11 green) by dropping 790 feet. Essentially all in play. (hole 7 is a short, flat par 3). Then, the battle is on back up to #18 by the clubhouse. Even the holes without elevation change between tee and green (eg 1, 18) have a significant drop and climb from tee to shot point to green.
Some interesting holes (I have photos if people are interested) but I would hate to walk the course carrying my own clubs or pulling a trolley. Most of the caddies at the Tenerife Open had understanding players - light carry bags. Some had the full size bag though.
A couple of holes reminded me of a black slope ski run. The cart paths had double switchbacks on a couple of holes (descending on #9, ascending from #4 green to #5 tee.
Just to repeat - 790 feet of elevatuion change from top to bottom, plus climbs up and down on some holes. Only three flat holes, all par 3's.
