Pros:
One big valley with a nice mix of elevation, spotty trees, and views.
-Amenities: Textured rubber tees, DGA baskets, tee signs with basic maps and distances.
-Environs: This section of the park is essentially a giant grassy bowl. Various sections of the course have nice overlooks of what feel like rolling, hilly pasture. Just as notable are some great views of downtown LA from one segment of the course. Other than some walkers on the perimeter, there isn't other traffic inside the course.
-Elevation: Two breathtaking downhills, several challenging side slopes, and some other moderate hilly holes. Definitely the most notable feature of the park, these slopes alone make for a fun course.
-Loop: A perfect loop of 9 holes. The last basket is just feet from the first tee.
-Shot Shaping/Gameplay: Nothing mind blowing, but a solid series of medium-length holes requiring a combination of angle control, big ripping, and light shot-shaping. There is a moderate number of trees that factor into every hole in some way, some more than others. Generally they form either very generous fairways or last-minute basket guardians. The hills need to be handled smartly, but also have a major fun factor as you smoke some shots off what feel like cliffs. One par-4 is a change of pace for the closing. There are several birdie chances for 300' throwers, and bogey should only happen on a flubbed approach.
Cons:
Pretty standard SoCal stuff.
-Technical Challenge: Or rather, lack thereof. Arguable there are zero technical holes; the toughest shaping gets is avoiding basket-guarding trees.
-Par-3 Standard: 8 out of 9 will feel like you should birdie them in two if you don't. It's not a particularly strategic course beyond controlling for elevation.
-Park Users: This definitely isn't the worst place I've seen for pedestrian traffic, but there were some at-risk sidewalks and two of the holes were being used for a picnic and a photo shoot.
Other Thoughts:
Kenneth Hahn is a fun little course thanks to a pleasant hills environment. You'll enjoy a couple of bomber shots and pretty greens. On the whole, it's not pushing any envelopes and I've seen plenty of courses with similarly elementary shot-shaping. I give it a Typical.
-Parking: There's a fee sometimes to park inside the recreation area. However, I had no trouble parking on Punta Alta Drive and walking in. It was just as convenient.
