Pros:
Great use of elevation.
Plenty of opportunity to work on your drives.
Multiple true par 4s and par 5s.
Beautiful property, very well maintained (especially by disc golf standards).
Pro shop with discs (a few) and snacks,
Bathrooms.
Cons:
Navigating the course can be a challenge.
Expensive (especially on Sundays).
Shared course with ball golfers, so look out for bouncing balls.
Other Thoughts:
I'm doing this review for a couple of reasons. First, the existing reviews are old and reference using golf carts, which are no longer allowed for disc golfers. Second, I'm guessing many folks who play Goat Hill will be out-of-towners, so this is sort of a guide to the first time player.
I played on Sunday, which meant the greens fee was $15. The course is also open on Tu and Th for $10. I suspect their are fewer ball golfers on weekdays, so if possible, play then rather on a Sunday.
Course navigation was a challenge, especially early on. I met up with another first time player, and we played to the wrong basket on #1. Later, we met up with another twosome who had played to the wrong basket on another early hole. The scorecard for the disc golf course includes a decent map, but it takes a few holes to get oriented. My tip is to follow the ball golf cart path from the golf green of each hole to the next ball tee and then look for the marker stump for your disc tee.
Once you figure out where you're going, though, this course is a ton of fun. About half the holes are par 4s or 5s, and these are the real deal for anyone without a huge arm. Many tees are elevated, while other holes climb significant hills. If you like to throw long, this is the course for you.
It would be nice if more holes really made you shape your tee shot, but I don't recall a single tee that had any obstacles nearby. That changes somewhat as you approach the baskets, as many of them are near ball golf greens and/or sand traps. There are a decent number of trees and bushes near baskets as well.
This is a lush, green (even in February) hilly property with lots of beautiful views. For folks who enjoy hiking, this is an excellent walking course. If you are used to walking shorter, flat, courses, this might be more exercise than you are looking for.
If I lived in the area, I'd play here at least a few times a year. It's a beautiful, fun course that every disc golfer who visits San Diego should probably play at least once.
