Pros:
Exposition Park is a flat, wide open, grassy plot of land interwoven with sidewalks and dotted with various bodies of water. It is truly an ideal course for beginners and intermediates because most of the holes play a straight line across spacious fairways blocked only by small, well-groomed trees. The park's hungry water obstacles claim more than their fair share of plastic, giving Expo a reputation for it amongst Denver's urban courses. Aside from the disc-eating ponds, whose presence poses the only real challenge on the course, it is a well-kept, attractive park. There are usually plenty of people out and about, but pedestrian and bicycle crossings very rarely interfere with the game and you'll never have to throw across a path from the tee box. The course's best features are its spacious cement tee pads displaying the hole number and distance, good quality baskets, trash cans, benches, overall upkeep, convenient location and lastly, let's not forget the 4 fun holes alongside the lightly wooded creek.
Cons:
Hole #1 is in the middle of an open field and cannot easily be accessed from either of the 2 nearby parking lots, which is a serious design flaw. The ponds flood at least a handful of times each year, leaving a ring of debris and trash 20 feet inland. Luckily, it's generally cleaned up in a few days. Even during the most lengthy droughts there are mud puddles behind and in front of many of the cement tees. In various places, the ground beneath the grass is like a soggy sponge and you won't know it until your foot is squishing into it. The tee box for hole #10 is usually covered in a film of greasy mud because it is too close to the shore. Geese overtake the ponds and shores in winter months and their excrement is everywhere.
There is very little elevation change to speak of throughout the course. Multiple pin locations would be a huge improvement. There is a wealth of free space for it on the existing course and as often as the Aurora Parks & Rec crews are out doing maintenance, moving the baskets would seem a very small task.
Other Thoughts:
PARKING: There are 4 different places to park that give access to the course: the main lot at the recreation center off Exposition Ave, the baseball field parking lot (southwest corner of park), streetside parking off Lansing St near basket #4, and the east corner of the Red Lobster parking lot which gives access to tee #12. These options are convenient if you want to play a specific part of the course or change up your starting point.
ALTERNATE TEES: There are some not-so-well-known alternate tees that play from the sidewalks. 2 of them are on the sidewalk to the west of baskets #8 and #10 and another is on the sidewalk behind the #15 tee pad. There is also one faintly marked on the sidewalk behind tee #1, which turns it into a very long fairway drive.
In a nutshell, Expo is a fun, convenient place for a round of 18. It is a valuable location whose radius is notably void of other disc parks. In that regard, Expo is Denver metro's best disc golf offering east of I-25.
