Pros:
The city views here are simply fantastic, especially from the basket for Hole 2. Despite the preeminence of shorter holes, the narrow paths do provide some challenge. Hole 3 might be the best hole, with a steep drop from the top of the ridge down to a near a winding road. Holes 6 through 8 are steep enough uphill to throw with higher amounts of power. Holes 9 through 11 wind around the side along a trail. I saw woodpeckers in the trees on Holes 1 and 2. Decent wood (or plastic?) tee pads are adequate. The existing signs are nice. Free course.
Cons:
Navigation is near impossible for first timers, especially between Holes 3 and 4, and Holes 8 and 9. Signs are missing from Holes 9 through 11. Recent overgrowth near Hole 12 ate one of my drivers. At first glance you might shoot at the basket for 9 from the tee for 1. The course map on this site is better than nothing, but not by much. The Elysian park courses seem to stump navigation devices.
Other Thoughts:
This 12 hole course occupies a boot shaped, approximately 10 acre sliver of land on Buena Vista hill. A decent course with some fun factor points. With less overgrowth this course would improve a bit.
