About the Park
This Rapid City off-leash spot sits along a drainage corridor near Idlehurst Lane, offering an unfenced place to exercise dogs with dependable recall. Because there's no fence and few posted amenities, it works best for owners who know their dog will stay close and come when called. Hours run daily from 5:00 AM to 10:00 PM, and there's no fee. Plan to bring everything you'll need, water, waste bags, and toys, since facilities aren't confirmed here. The open, natural setting suits dogs who like room to roam over manicured features. Keep your dog within sight and away from any water flow in the drainage. Leash up near the road and parking areas.
infoWhat to Know Before You Go
Best of all, Knollwood Drainage/Off Leash Area is completely free to visit — no membership or daily fees required.
