Pros:
Between the two separate 9 hole courses there is a nice variety. A fairly good mix of holes, mostly open. Ocassionally the river comes into play adding to the scenic nature of the courses. New catchers...Hole 4 (Lava Pool Course) should be the signature hole with an elevated green and mountains behind. Best place I have ever seen for an "Ice Bowl" event, throw discs in the snow and soak in the hot springs after. What a great way to spend a day.
Cons:
Still some work to be done on both courses. No permanent signs or tee-pads yet, locals seem to be working on this. Without local help it is a bit tough to work your way around the two courses. Additionally in the summer, the last couple of holes around the pool can be quite crowded with people floating the river. (At the same time this means that bikini sightings are always possible)
Other Thoughts:
I think it is important to note that there are actually two separate courses here: the 9 hole "Lava Lions Club Park" which has a lot more elevation change, is less "domesticated", long grass, brush etc., and plays a lot more with the river. (Hole 9 on this course is incredibly fun to bomb down from the hill to the catcher backed by the river)
The Lava City or Lava Pool Park course is on the grassy areas surrounding the pool and waterslides mostly open, and more family friendly than the other course.
I should also mention that while you can see one course while playing on the other, there is no way to walk between the courses.
Both are absolutely worth playing if you are stopping to soak or just passing through.
When teepads and signs are in, the rating will go up! Lots of fun...
