Heritage Park is the first course in Homer Glen, a suburb just north-east of the Joliet/Lockport cluster of courses. It's a red/white level, 18 hole course with (currently) 3 multi-throw holes set in a nice grassy park with sparse mature trees and relatively flat terrain outside of one large (by Illinois standards) hill. Playground and other recreational equipment looks to be installed within the past year or two and everything looks really nice.
The terrain features are minimal, but well used. There are numerous large low mounds that often have a basket on top or directly behind. The large hill comes into play on two holes. The tee for 14 is on flat ground, but the basket is near the top of the hill (guessing +20' elevation gain). Hole 15 tees from the hill top back down to the flat and has a few mature trees to contend with starting near the bottom of the hill.
Water in play on 3 and 4 - Hole 3 is a good risk reward par 3. The basket is on a narrow strip of land between two ponds. In range for most everybody, but if you're trying to get in the circle there's a small margin for error. Hole 4 plays next to one of the same ponds from the previous hole. You can absolutely play it safe (wide left) on the drive, but the basket is on a mound and missed putts can easily roll into the water.
Baskets are new, solidly built, and catch well. Currently tees are crushed gravel, but the course page indicates that concrete tees are in the works.
Multi-throw holes are good lengths for the intended skill level and each has a feature that the others lack. Hole 5 has numerous low mounds in the second half of the fairway. Hole 6 has a mando halfway down the fairway. Hole 18 requires navigating a double mando between two trees to enter the green.

Routing - See other thoughts. Lots of walking between holes and the way to go isn't always obvious. You can read through my notes on routing below (which should convince you that a map is a good idea). While I like a lot of the individual holes, I have to think this isn't the ideal layout.
Safety - Walking path is in play on a few holes.
Lack of obstacles - Grass park course with sparse trees. The trees that are there are generally well used to force shot shapes, but the designers didn't have much to work with. You can miss your line badly on most holes without much penalty.
Distance Variety - Almost every hole is 300; +/- 25'. Even the par 4s are multiples of this number. Whatever your workhorse disc is for that range will get a ton of use.
Signs - Concrete pavers installed flush with the ground have hole number and distance. These are no help to first timers trying to figure out if they are walking to the right tee. A couple were already cracked badly.
Mandos - In addition to holes 6 and 18 mentioned above, 16 also features a double mando. I like the way each hole plays with the mandos, but I think they are being used to cover design flaws. Hole 18 is a prime example. Forcing the player to enter the green from one side adds character to the finishing hole, but it also seems intended to avoid players going wide left on a hyzer and crossing over the walking path that runs parallel to the fairway for the last 100'. We all know that not all players obey mandos and they aren't an effective way to keep discs away from other park users. The other two holes with mandos, 6 & 16, play parallel to each other and the mandos seem to be there to keep players from playing through the area in between the two holes. Right now that area is overgrown enough to be a deterrent on its own, but I could easily see local routes developing through that area.

Notes on Navigation: Hole 2 is not the 600' par 4 listed in the hole details or shown on the map. It looks like the basket location is as shown on the map, but it's been shortened to a 250'ish rhbh hyzer. After Hole 1, follow the walking path for a few hundred feet and then look for a tee along the fence line to your left (before the evergreen). When playing the par 4, hole 5, you'll see the tees for first hole 6 and then hole 16 on your way to the basket. After hole 6, do not walk to the tee pad that you can see (that's 14), but walk between the squash courts, past bocce, and across the parking lot to 7's tee. From 9's basket, cross the park road to 10's tee. After 10, cross the park road again to 11's tee on top of a low, wide mound. After 12, cross the parking lot and follow the path for a couple hundred feet to 13's tee. After 15, you'll walk past hole 6's tee to get to 16.
Despite its flaws, this is a fun course. When permanent tees are in and if Hole 2 is ever lengthened to the originally intended 600' par 4, I could see upping my rating to a 3.

- high quality baskets
- expertly manicured park which is being redeveloped and continually improved
- one water hazard
- variety of distances/some par variation
- play on each hole does not conflict with others
- incorporates any elevation change available, and works in plenty of tree hazards despite being open
- some garbage cans around
- public restrooms on site

- hole numbers/par/distance on ground can get covered with debris and hard to read, and can't be seen until you're on top of them
- gravel tees are just ok
- no tee signs/maps, making navigation quite challenging at first
- have to cross parking lot twice during play, could use a map depicting this
- significant wind in open area
- limited elevation change/obstacles
- baskets aren't labeled with hole number
- some throws near walking paths

This is a brand new course and there are still some growing pains to work through. It would really benefit from some tee signs with maps, next tee indicators, and a course map. However, the biggest single improvement would be to add numbers to the baskets to make it clear which basket goes with which tee. In a course this wide open, this can get quite confusing. Navigation was one of the trickiest parts, and thankfully I found someone who had already played the course. You have to cross the parking lot twice and the driveway to the parking lot twice during play, so it's not always intuitive. Since the hole numbers are on pavers in the ground, you can't really spot them from a distance, further increasing the challenge.

Overall, Heritage Park in Homer Glen is very nice. It is currently being revitalized and you can see the effort going in to this park. Other amenities include walking paths, tennis/pickleball courts, sports fields, etc. I've heard improvements should be coming to the disc golf course, including OB markers, concrete tees, etc.

When I played, Hole 2 was unavailable for some reason. I couldn't tell why but there were signs and they had pulled the basket. Hole 3 was pretty cool as the approach to the basket lands you on a narrow isthmus between two ponds. It is a big time high-risk, high-reward shot. Otherwise, there aren't really any other water hazards. A few hills are incorporated to make the terrain as interesting as possible, and there are small hillocks in places, but most of the course is flat and open. Despite not having real wooded sections, there are plenty of trees which do come into play. Hole lengths range from mid-200s up to 600 ft. Thankfully, there wasn't much risk of interfering with other groups - this seems fairly well thought out despite the openness of the course. Hole 18 likely will appear to most people to be a practice basket, being so close to the parking lot. It would be better to shorten it a bit (it's 600 ft) and put in a separate practice basket - and label them!

For some navigation help: upon driving up the the park there is a long driveway to parking areas. If you take this to near the main area of the park with the tennis courts, entrance arch, etc. you are near hole 1 (to the far left of the arch). Holes 1-6 play around this area, and you have to then go back through the middle of the sports court area and across the parking lot, where you will find holes 7-9. You then cross the driveway to play 10, and cross back to play 11-12. At that point you cross the parking lot again to 13, and the rest of the holes play on the same side of the parking lot as 1-6, with 18 depositing you right back at the parking lot.

During my round it was insanely windy, making me really second guess some approaches to my shots. It may not be this bad normally, but considering how open the park is, I suspect wind will often be a significant factor. Navigation was the main frustration here, and I would rate this course higher if some of the basic course amenities were improved. It can be a solid course with some simple additions, and is a nice place to play if you're in the area. The Lockport/Joliet area courses a bit south are still far superior, but this course is worth a try.
