Pros:
-Beutifull location with hills, valleys, creeks, mature oaks, wildlife, and great views.
-Lots of variety, uphill, downhill, sidehill, across valleys, left turning, right turning, etc...
-Secluded seting in the hills of Napa, close to town, but far enough away to not feel crowded by the city.
-Challenging. I saw some of the best players I know chewed up by this course.
-Benches on most holes
-Area of the park thats not used much by other park users
-Fire Extingushers on every hole
-Multiple pin positions on all holes
-Rubber teepads in good condition with brooms on each hole.
-Great Locals, these guys are lots of fun.
Cons:
-Some holes almost require you to throw a thumber (hole 15).
-"Napa Rolls": The art of landing within 20' of the basket (or hitting the basket) then rolling 300' down the hill behind you.
-Signage didn't feel 100% accurate.
-Not a beginers course, as it will beat up on even an experenced golfer
Other Thoughts:
Napa is a beutifull course with many great fun holes that will both challenge and entertain players with some experence in disc golf. For beginers and people who are out of shape this course will frustrate and wear you out. It is full of massive elevation change throughout the course. Some holes I thought were a little unfair if you don't have a big thumber in your bag (hole 15). Everyone it seems, no mater how good you are, will get at least one disc that will roll away and down the hill way far away from where you want it, this is just the way it is, that's Napa for you. Make sure to bring some snacks and water as this will be a long round.
