Cassiobury Park is Watford's secret gem - not too far from the town centre. The park is a tranquil and relaxing place, and also a great location to walk, run, fish or, down by the canal, simply watch the boats glide past on the Grand Union Canal.
The canal passes along the western side of the park, not too far from the splash pool and playground, and separates it from Whippendell Woods. There's a superb hump backed bridge just over the lock, a great place to watch boats pass and there are a couple of benches on the side so you can put your feet up and gongoozle to your heart's content.
