I can't think of them all in the Westchester Area, but WFE & W has three testing, but rewarding, uphill Par 3s... 3 & 13 W...a maybe the single most brightened hole in the Hanse renovations last decade, 6 East; that's almost a perfect uphill par 3 imo.
Another uphill one on the WF courses is 7 West, which though it reads as an everyday 150-160 hole can be a frustrating, and delicate clubbing as the target may be the smallest of WF's 36 greens, and either hits it or goes bounding off its push-up/false front design...add to this that the tee is slanted just a bit uphill to a small uphill target, quartering/into the prevailing summer wind, and you learn over time, that day's "hit" itself has to be right, not just the clubbing. . It's called Babe in the Woods and it belles the trouble you can get into on what seems to be a straightforward mid/short iron....It's the one Miller made a mess in the cavernous front right bunker to a big number.
It's almost too audacious and taxing to be great, but Siwanoy's 13th is an inspiring altar-piece played over a large bunker, blind to a wild, thumb printed green (softened and expanded in its last Devries shovel), steep from back to front. Even at the more modest white tee yardages in the 165 -76 range, this plays 15-20 yards more with the ascent and into a prevailing west wind.
I dislike almost all of the Knollwood course, save for a few holes and one of them is the short 2nd, which plays only a whisper uphill, but is that rare dink (105-130) yardage hole without water that manages to be equally dangerous and rewarding, according to how well judged/played the shot.
Though the course has seemingly fallen in esteem or notice from where it was 20... 25...30...35 years ago, Stanwich's 13th remains an honest aerial midiron over a meadow pond to a clover shape green featuring a tapered spine at its midpoint. The job never seems to be over even once the green is achieved, and the green complex seems to complicate every pitch and chip scramble for up and down.
