This park is located next to the Superette in the Cultus Lake Plaza, across the street from the Cultus Lake Waterslides. It has a very large, fully-fenced and gated field with a poop bag station and one picnic table.
If you and your dog get tired of the enclosure you can use the gate at the other end (south end) of the park to enter the off-leash trails which wrap around the Cultus Lake Golf Course and back onto Sunnyside Campground and the residential area.
