It looks and feels like a smaller version of Muddy Run. Same baskets, same cement pads, and a very similar look and design, just shorter and not as hilly. You are unlikely to lose a disc in the woods, the most dangerous place is the high grass in the open fields.

The first three holes are unusual and gets you off to a great start

It's mostly wooded, but the corridors are not brutally narrow.

Good mix of woods and wide open spaces.

Lots of places to sit if needed.

Holes 7-10 are dead straight in an empty field with high grass on every side. They do what they can by mowing interesting shapes but if you go off the mowed areas your disc can bury into the high grass.

Lots of parking but then you have to walk quite a ways to #1. Starting on #2 would be a much shorter walk.

This is a similar course to Muddy Run, just shorter and not as hilly, with fewer long downhill shots. Holes 1-5 veer in, around and through the edge of some woods, with lots of fun shots. 1 tees off right next to a cabin, through the trees, over a creek, out into an open water retention basin, with the basket on the ridge. It's a very fun short par 4 to start, although I think they play it as a par 3 in tournaments, which probably nobody birdies. Number 2 is a fabulous par 5 that you should birdie every time, yet I've struggled for par both times. I think they play this as a par 4 in tournaments. From the tee pad there is 280 feet of open air to the edge of the woods. Then a small gap which leads into a beautiful clearing where the basket sits behind a little pool of water. Should you lay up then fire one into the gap? Go for it off the tee? Go for it in 2? There's lots to think about and it's nice to look at. 3 is a fabulous par 3 that plays around and sometimes over the creek.

Like Muddy Run, after a brilliant start, there's a bit of a lull. At Muddy Run holes 6-9 are mostly open although there is still some strategy. Not so much at Twin Grove, where holes 7-10 are in an open, empty field and dead straight. There are mowed fairways that aren't very big, and if you go into the high grass there can be quite the search for your disc. After 4 holes of what pretty much is a slog through a field, 11 is a cool open air par 4 down and up through a valley with a series of little unmowed areas. It's a weird looking, fun hole that cheers you up after the slog of 7-10.

12-18 are all par 3s in the woods of varying excellence. 15 and 16 would fit in at Muddy Run. The only sort of weak hole would be 18 which is a relatively short hole, about 240 feet, but it's up and over a hill so it's blind. It's kind of an anti-climactic finish.

It's a pretty easy course to walk, none of the tee pads are very far from the previous basket. There is a bit of weird navigation from 5 to 6, you pretty much have to walk right in front of 16 tee. There's no warning, so you'll need to watch out. Also, 11-12 is a bit awkward but you'll find it. It's not very far, just kind of hiding behind one of the cabins.

17 is the only hole with 2 tee pads. The tee you'll probably walk to after 16 at the top of the hill is probably not the one you'll want to play, as it is a long dogleg right which aims you directly at the basket for #4. My guess is the owners realized this is pretty dangerous, so they built a second turf tee pad which is at the bottom of the hill. This is the only non-cement tee pad and is in very nice shape. This tee makes it a better hole as well as you are not firing directly at another hole's basket, and you have a nice corridor to play down. I'm not sure if they can move the cement pad down the hill but there's no reason to play #17 from there.

I think the only change I would make is to start on #2 and finish on #1. #2 tee is the closest tee to the parking lot and finishing on #1 is much more exciting than finishing on the current #18 and then walking 300 yards back to your car. #1 basket is relatively close to the parking lot. The second time I played here we started on 2, finished on 1 and it was an exciting finish plus a much shorter walk to the car.

I'm not sure what to suggest for holes 7-10 though. They do what they can to make them interesting, but short of adding gates or obstacles, turning #9 into an island, or making the high grass OB, there's really not much that can be done

Overall I really liked this place, yet another really good Lebanon County course. I live in Lebanon County and can't believe I never went there until this week. Then again, I have South Hills, Lenni Lenape, Jackson and Lakeside all within 15 minutes, so I guess I never felt the need to drive 35 minutes to Twin Grove, but it's worth the effort.

-Good variance of shots for the most part. From the tight wooded shots to the wide open field holes I was constantly being challenged. They used the terrain very well.
-Although there are a couple places where flow could be an issue, there is a course map available at the camp store.

-As other reviewers have said, the rough is real rough. I ended up with many cuts on my legs trying to get through some berry bushes to a disc. Also the long grass on the field holes (7-11) took one of my discs and tried to take a couple more.
-The field holes got a little tedious after a while.
-Although it was fairly dead when I went, I have the feeling that if the campground was busy it would hinder play. There are a couple holes that go right past cabins or RV's.

A nice drive through a state park to get there. The camp store has innova discs for sale and water/other things. You have to park and walk to the first hole, but there are signs leading you there. Holes #8, #16, and #17 were personal favorites.

I have played other camp ground courses and you can tell Disc Golf plays second fiddle. More time, energy and money goes towards the other amenities and the disc golf course is just an after thought.

Not true at Twin Grove. It seems a lot of time, effort and money went into designing and building this course. The course winds through a beautiful camp ground making use of area's not competing with other camp activities. There is a nice combination of open and wooded holes playing for both righties and lefties.

Great tee pads, tee box signs with map, length and next tee box location, brand new Mach 5 baskets, seeded fairways (even in the woods), and manicured grass in the field. It really was a great surprise.

Plenty of parking, restrooms, and camp store.

Being a new course no map was available yet. Course navigation was tricky in some spots but will be worked out with the addition of course map and maybe arrows pointing towards next tee box at baskets.

Holes 15, 16 & 17 play across a walking / biking path; although I did not encounter anyone. The basket for 7 is within 30 yards of a cabin.

Like I said before, this is a beautiful camp ground, and the cabins and bathrooms are incredible. I foresee a weekend Disc Golf outing with a bunch of guys, renting the cabins next to hole 7, Playing 18 in the afternoon, setup a small glow course using 7 - 11 in the evening, steaks, beer and a campfire, and waking up to 18 the next day.

This course will definately get better in time.

I will definitely be playing this course again.
