Whippendell Woods & Cassiobury Park — the closest, and the best-rated.
The morning pick — shortest drive and the highest rating of the three. The loop runs through ancient woodland (a Site of Special Scientific Interest) down to the Grand Union Canal and the River Gade, then climbs back up through the trees, so it gives a Vizsla genuine variety rather than the same view for an hour. Off-lead through the council-owned woods; lead-on along the canal towpath and across the short golf-course section. This is the stretch of Whippendell that stood in for the Gungan forest in Star Wars: The Phantom Menace.
Lunch: the Cart & Horses at Sarratt, an independent country pub on the woodland edge with water bowls and a big garden, about ten minutes on from the Cassiobury car park. The Cha Cha café inside Cassiobury Park is the quicker option if you'd rather not move the car.
