Pros:
Hanns Park is a really beautiful park with shaded Eucalyptus groves, picnic and bbq areas, an ampitheater where they perform Shakespeare in the park, restrooms, hiking trails, and open fields. Unlike most city parks there are no sports fields or playgrounds to draw activity, because of this the homeless and drug population moved in and nearly ruined this beautiful park. Enter disc golf to reclaim the park.
The disc golf course consists of 9 teepads and 18 baskets, color coated with blue and white Innova Dispatchers. The temporary signs mentioned in the other reviews have been replaced and updated with metal signs. On the temp signs it looks like they were planning on having a yellow basket but decided against. The new signs show the blue and white baskets with two possible pin positions for each per hole. They are using a unique marking system to identify which position you are throwing to. They are using blue and white magnets that look like they came out of a magnetic travel board game. They do the job but is real easy to slide them everywhere. There are huge level concrete teepads on every hole. The course plays through a beautiful Eucalyptus grove and very much reminds me of a small Golden Gate Park.
Cons:
There are a few safety nitpicks here and there but nothing major. Some of the teepads are located pretty close to baskets, but it doesn't appear to be that busy of a course.
There is some small navigation issues. When you finish hole 3 turn left and walk up the road, ignore the teepads right in front of you this is hole 8. I actually ended up playing hole 8 and was looking for hole 5 when I realized what I had done.
The course could probably use some more benches and trash cans on holes, but there are a few, and it is a very minor nitpick.
Other Thoughts:
I enjoyed my time here. Most of the holes are on the shorter side with only a few over 300, but most are technical. Hole 7 features a cool downhill island hole that is about 200 feet away but has bushes blocking the easy forehand or backhand hyzers. You really need a straight touch shot to get this one. All in all I would say this is a great park 9 holer.
