-some open tree-free space to fire away
-a few wooded technical shots
-convenient for some residents of black butte ranch
-nice concrete tee pads
-hole numbers on wood post at most pads
-pretty easy to navigate (other than finding tee pad 7)
-doubt it's ever crowded
-parking near hole one
-decent views of the mountains (if it's not cloudy)

-baskets are below average.. but passable
-the open shots play over ankle-breakin' field grass
-hole 9's baskets is out of commission.. seems to have been this way for some time
-no signage from hole 6 to hole 7- must use udisc map
-no elevation change or wow factor

I was excited to be staying at Black Butte Ranch over the New Year's weekend and to get a chance to play disc golf every day! To my surprise, the ranch is quite large, and the course itself was a solid 2 miles from our house.
We drove there, played it once, marked it as 'played', and did not return.
I agree with the Valkyrie Kid- most holes are too long for beginners/casual residents, but the layout is too boring for serious disc golfers. After playing the first 6 holes and being ready to get out of there, we finally got some more fun wooded shots (3 of them!). But as my heart began to open up, it was struck down by having to play hole 9 into hole 8's basket.
It was like the feeling you get from finding a new disc with no number on it and then having the group ahead of you ask if you happened to find a disc back there that they left behind.. Not how I wanted to finish up the course.
If you are driving by, it's pretty close to the main road (and free to play) but I certainly wouldn't recommend this as a must stop.

Other notes- there are some play toys by the parking lot if you have kids and there is also a nice paved trail through the ranch if you want to go for a bike ride or walk your dog or something.
