neptune park has soccer fields, pickleball courts, baseball, and picnic tables; the disc golf plays through or near them, so if they're being used you may have to skip holes. the pool is right off of 9/parking lot; a hot summer day might make that area full of people. the town of rupert isn't very big, so it's unlikely these will ever be busy, but there is a chance.
some interesting & semi-challenging shots playing sidewalks & streets ob, but the majority of holes are open shots in a park. it looks like they put pickleball courts in after the design, so hole 7 is playing directly across them. hole 2 is likely the most challenging, with the basket at the end of a line of trees; but some might say 7 is difficult because you play across 3 different chain link fences with 2 large cottonwoods in the middle.
this is an easy stop if you're on your way to play walcott, but not worth the 6 miles (12 roundtrip) off i-84 on it's own.
