Pros:
Devil's Den boasts multiple amenity-laden, mostly open layouts to provide fun and challenge to every mood and skill level. More than any other non-ball-golf course I've played, Burchfield Park's Devil's Den course puts disc golf on par with our more well-known brethren. Every hole is outfitted with dual concrete tees and dual Chainstar pins, each of which features a large flag identifying the hole number and layout color. Boundless amenities add to the professional sheen, including benches, next tee signs, well-built wooden structures/obstacles, and on the 92 degree day that we played most recently, large water jugs strategically positioned throughout the course to refill bottles. Maintenance was impeccable, with every hole mowed and devoid of trash. This is the kind of pay to play experience that makes me happy to shell out a few bucks ($3 entry fee for Ingham County residents, $5 for non-residents, plus $4 per player) for a superior round or two.
The design is pretty solid too, with the dual tees and pins offering different looks as opposed to simply added length. All layouts are what I would call open strategic, where hitting the preferential landing zone is helpful but not essential to achieving low scores. This is a high fun factor course which maximizes the time spent throwing discs while minimizing the time spent searching for them. There's a clear skill level division on display in the layouts, with short to short offering a good layout for casual and rec players, short to long for intermediate, long to short for advanced, and long to long for pros. The long tees add an especial layer of difficulty, begging higher skill levels to attack the holes with nontraditional shots (i.e. rollers and, on Hole 2, a thumber or tomahawk tee shot). Old sand traps play as OB, and finding them is not as difficult as you might think. I speak from experience... Individual hole highlights include the gauntlet Hole 11, with its heavy premium on hitting the correct (left side, but not *too* left) landing zone to score well, and Hole 17, an attractive island green playing as a fun little late-round gut check that isn't punishingly difficult.
The Hole 18 Gold green deserves special mention, as a landscaped rock outcropping resplendent with a small fountain that wraps up the round in a neat little bow. Little touches like these make Devil's Den feel like a cared-for priority at Burchfield Park, a breath of fresh air compared to many other county park courses.
For a busy park, the area Devil's Den sits on is pretty exclusive to disc golf. The dirt road to and from the maintenance building sees a little bit of traffic, but the non-golf foot traffic on the course is almost zero.
Cons:
There's a decent amount of overlap between the Holes 11 & 15 fairways, and it's not too much of a stretch for drives to end up in the way of another group. Golfers should be aware of players on the companion hole and adjust accordingly.
I would've preferred a little bit more hole variety (flat and sparsely wooded is the name of the game), but most of that can be found on River's Edge, the other course on site.
Off the fairway, the rough can be a little thick and laden with poison ivy, but it's still much thinner than River's Edge.
Other Thoughts:
Devil's Den is the rare public course whose generous amenities nudge up the course quality and rating by a measurable amount. Even if the open design style isn't your bag, only the most sour discer could leave here feeling like they didn't get their money's worth.
