Pros:
UPDATE: I have edited my review to reflect the new, permanent layout. The course greets you after a short walk with a practice basket. Unlike many Denver area courses, this course has plenty of old growth trees. Many baskets are situated directly next to low hanging branches. This also provides plenty of shade relief for those hot days.
The course makes great use of available land and features, and forces a variety of shots.
Distances vary from a few in the 150ft range, to #18 which is 450+. The average hole is about 300ft.
Located in a nature preserve, there's not much other foot traffic on the course. You are fairly well isolated from other parts of the park. The course has had it's rough area's cleaned up, so there are defined fairways for each hole, and, at time of writing, a low chance of losing a disc. There is a well maintained PortoPotty on site, as well as a water pump.
The course is well designed for safety. Most tee's are protected or situated away from other holes. Only two holes come into contact with a sidewalk. It is also easy to navigate, the course flows fairly naturally, only 7 to 8 isn't plainly obvious (8 is located by the sidewalk near the railroad tie fence).
The yellow Innova DisCatchers are easy to spot and catch very well. The recent update to the course has blessed it with concrete tee pads, which are just barely long enough but plenty wide. Additionally, most of the front 10 was changed, permanent signage for each hole and multiple pin positions were added to almost every hole. There are benches and trash/recycling throughout the course.
Cons:
UPDATE: The redesign/update addressed most of the common gripes found on the original design. Its hard to find much fault in the course now, but nothing is perfect. Tee pads could stand to be a few inches longer, though they are still very good. There are no navigational markings (yet); it could be tough for a first timer to find 8's tee and 18's basket. There's about an 1/8th mile walk from the parking lot to the first tee.
Other Thoughts:
Designed for beginner to intermediate players, this park is a great compliment to nearby Benedict Park. Overall this is a fun course to play. The update was done right, and addressed nearly every complaint, so there's really not much to dislike.
