The Final Verdict
Arrowsmith Park is a practical choice for Penshurst locals with well-trained dogs. It isn’t a fancy setup, but the open grass suits a daily workout well. You’ll need to stay a vigilant owner given how close the main road runs, but if your dog has reliable recall, it’s a good spot to let them fly.
