This is practically a picture perfect version of what a college campus course can be like.
Fun.
Good mixture of short vs. long throws.
Nice tee-pads/baskets.

The creek runs right through the middle of the entire course. The first time you play this course it seems like an ever present hazard. Once you get used to it you hardly notice that it is there.
Some of the locals don't understand basic FROLF etiquette.

All of the signs are missing so if you enter the park from Falls just park on your left and find the first hole. The rest are pretty self explanatory. You play down the creek and then circle back. You follow the creek more or less the entire time.

The College of Southern Idaho makes use of their beautiful campus with this awesome 18 hole course.
The Tee's and signs are well maintained and provide the proper hole information (Pinnacle location, Par # and visual to next Tee)
The fairways are always groomed and people do a good job of cleaning up after their animals.
OB is marked by the Creek that runs adjacent the whole course, the opposite bike path that is covered with tree bark and a few parking lots and access roads.
The course has a moderate amount of trees that you play around, most with long fairways and a couple with hills that make it interesting.
Nothing too special or overly elaborate on this course but it is a very very solid intermediate course and the environment makes it all the more enjoyable.

The Creek is very easy to lose discs in. Although they do make a somewhat feeble attempt to keep the bank long with grass as an effort to slow discs down, they still go in.
If you don't mind getting soaked it's usually not too hard to find your disc laying on the bottom with the rocks.
And i'd recommend that if you do want your disc back not waiting till the end of the round because people do float it with the soul purpose of finding and selling them.

Water and facilities are located at the softball fields that can be found directly across the parking lot from Tee 1.

Great course. Winds through a small nicely kept park with rolling hills. Despite the park's small size, the course was very well laid out and the physical features were well utilized.
A small but quick running creek runs through the length of the course and provides a good challenge.
Hole positions provide opportunity for getting creative with your shots.
Great signs at every teepad showing the hole, length, par, and directions to the next hole. I pleyed by myself and had no problem finding my way around the course.
Elevation changes! Im used to the flat course in Boise, so some hills were fun.
Im not a local so Im not sure of the usual traffic, but it was utterly deserted the morning I played. Just some college kids on the paths and a few people walking their dogs.

Nothing major to complain about!
The creek was running full blast, as it had rained all night and morning. It gobbled up a one of my discs... A floating disc probably wouldnt help, unless you like to run...

Marny holes are ~300ft or so, which was great for my noodle arm, but the course lacks lots of long holes for the big bombers.

Really fun course. I would recommend it to any one passing through Twin.
I found a few shops in town that sell discs too: Claudes and Donnely Sports.

Well laid out course with a good mix of shot requirements. The playful little creek throughout makes the course a lot more fun (it is big enough to be in play, but small enough to cross and usually to find any of your wet plastic). Tee pads and signage are certainly adequate. It is in a well maintained part of the CSI campus that is also quite family friendly and clean. Basket placements are fairly well laid out in my opinion, and different skill levels can enjoy what the course has to offer and the layout if fairly logical in progression and it was fairly easy to find the next tee pad and hole. While you will occasionally see people on the walking path, or students wandering around, for the most part it is well placed away from non-discers.

If you have a really big arm and are looking to air it out over and over, you might be disappointed here. There are a couple of longish holes, but nothing for the giant arms out there. Also if you like elevation change, don't look for a lot here, the course is fairly flat. All in all there are not a lot of cons here, one of the better courses in the area.

This course and the Rock Creek course compliment each other well. CSI is much more family friendly and easier to follow. Yet, Rock Creek is unique and requires a very different type of play.

Worth the stop in Twin Falls to play the two courses. Just know you are in for a very different experience with each.
