Pros:
This course was where I first played a round with "true" golf discs starting fall of 2002 [though I first played Frisbee golf in '79 at USM], so I have great affection for it.
Its matured beautifully in the 18 years I've known it. Gone are the impenetrable walls of blackberries that stole many a disc from hole #4 on. Hole #s 1-7 cross or parallel a creek and small pond, with much elevation variation, while traversing nicely manicured fairways through the second growth oaks, pears and apples that are overwhelming an historic orchard.
At #8 you'll enter the forest and the lines get woodedly tighter among the alders and cedars, though at # 11 you'll return to the field for one last big-airing before you enter the Douglas fir forest on the next plateau down.
#s 12-18 have little elevation change[unless #14 is in the upper position], but you'll be too busy shaping lines through small sections of fairway and the maze of trunks to think you're being cheated by the flatness of terrain. 30-40 ft below the immediate left of #s 15-18 is a soggy, openly-treed riverbottom that will really get the score meter ticking if you do an exploratory drive.
An incredible variety of shots are required here-you need BH and FH, anhyzer, dead straight, and among the trees, sometimes a prayer.
The tees, baskets and upkeep are excellent, and the links are a dedicated 30 acres separate from other human intervention. Benches at every hole and trashcans at most holes. The course begins to get crowded when the weather improves, starts to stay daylight till 7 pm or later, or summer arrives.
Cons:
Most of the baskets are hidden from the tee, so a local, scout or map is handy.
#2 has the road to the lower parking lot pretty much as the right half of the fairway. Fortunately this end of the park is all DG traffic, so cars pass only sporadically.
If its a wet winter, it will be soggy and/or muddy on a number of the holes, notably #s 1, 2, 5-8, and 12-13.
Discs are easily recoverable from the creek, but the pond is quickly over your head on the west and north, 2 ft. of mud on the east, and becoming solid ground on the south.
Other Thoughts:
$5 per car, so carpool, use a yearly park pass or hunt for parking nearby outside the park[a lot of this has been eliminated, thanks to the ODOT] #1 is near the practice basket next to the upper parking lot. Bathrooms are in the lower lot and the boat ramp area, which also has the only functional water faucet. A decent local store is 1 mile east on the road, where yearly or daily passes are available. Great full-day loops exist with Dabney, Timber and Milo McIver; or Dabney, Rooster Rock, Locks Approach and North Bonneville. .
