Pros:
I played the Summer 9 as they didn't have the winter course in yet.
These nine holes play clockwise around the small lake. As a RHBH player it is helpful that my shots fade away from the lake. The water would be a more significant hazard for LHBH or RHFH players.
While the trees in this area are not tall, they are brushy and thick, so missing your drives will require some "get out of jail" shots. Most of the holes have a narrow fairway that you'll need to hit, and a couple also have a low ceiling to work under.
Good range of hole lengths from 242 to 465 feet.
Huge parking area, nice restrooms and water fountains. Decent rubber fly pads that are starting to show some wear, and basic fiberglass tee signs.
Cons:
This is a multi-use park, and a jogger came around a bend on the Hole 1 fairway just as I was getting ready to drive, so look out!
The tee signs are very basic and show two or three basket locations, but there is no way to know which pin is in use. On about half of the holes it is necessary to walk up a ways.
The area is brushy and overgrown, so you'll need to keep a close eye on your drive. Hole 6 had additional pathways mowed left and right of the main fairway that made it easier to chase discs.
Other Thoughts:
It looks like the additional "Winter 9" would add a lot of interest to this course, as they play across a park-like area with large mature trees and rolling hills.
I am pleased to see another Idaho State Park with a decent disc golf course.
