Football - Four pitches (booked every Sunday by two local football leagues, but available at other times on a casual basis, between September and April). To book, call 020 3567 6900 or email email@example.com. Use of changing/shower block is included in the cost.
Cricket - A cricket pitch is marked out in summer and is used regularly by local clubs.
Tennis - Hard courts (all year), grass courts (in summer). All tennis courts are free of charge. The Grosvenor Lawn Tennis Club uses three of the grass courts throughout the summer. For more information on the club, call Ann McKeever on 01923 351627 or email firstname.lastname@example.org.
Bowls - Watford Bowls Club is based in Cassiobury Park. They have regular events where you can come and try either lawn bowls (summer) or indoor short mat bowling (winter). For more information please contact Keith Brain at email@example.com or call 01923 256192.
Cycling - There are designated cycle paths in Cassiobury Park. To protect the vulnerable (SSSI) environment of the Whippendell Woods please only use the perimeter path. There is actually a bylaw prohibiting cycling in the rest of the woods due to the impact of wheels and jump construction on the rare plants and fungi.
Table Tennis - We recently installed two tables by the tennis courts. Come along to play for free! Bring your own bats and balls or borrow from the Cha cafe.
Horse riding - Horses may use the perimeter path in the Whippendell Woods.
Fishing - Watford Piscators fishing club own the fishing rights to the bank of the Gade nearest the canal and both banks of the Grand Union Canal. You can buy a day fishing ticket from them (in the fishing season). If you're aged 12 or older you must have a national rod license to fish elsewhere in the park. You cannot fish anywhere between 15 March and mid 15 June. (Children can still fish with nets in the river at any time.)
Basketball - One of the hard tennis courts also has basketball nets.
Other sports - Aside from the official marked-out pitches, there is plenty of open space for a kick-about or a game of rounders.
