Dundurn Castle operates as a civic museum, and its grounds house other attractions.
Dundurn Park and its associated green spaces are favourites for wedding portraits.
The Cockpit Theatre occasionally housed outdoor events and dramas.

A large German artillery piece, booty from the First World War, was removed from the southeastern part of the park in the mid-1980s.
 Until about 1990, it housed an aviary which was moved to the Westdale neighbourhood.
The former covered pavilion offered picnickers protection from the cold, but in the last few years a walled garden was put in its place.
The gates at the front entrance of the park originally came from England, but the stone pillars were cut from the Dundas mountain.
In 1931, parts of the gates were removed and taken to the Chedoke Golf Club.

Dundurn Park has its own folly, just east of the castle.
Living up to its purpose, it had confused some people who had considered it a theatre, a laundry, a boat-house, a buttery, an office, a chapel for Sir Allan's Roman Catholic wife, or even a cockfighting ring, although no proof of the last use has ever been found.
Urban legend has it that many tunnels were built, leading from the Castle to various parts of the estate and one of the entrances was through the folly.

Sir Allan Napier MacNab was originally buried in 1862 on the Dundurn Park grounds between Dundurn Castle and Castle Dean on the corner of Locke Street and Tecumseh Street.
In 1909, his body was removed and taken to Holy Sepulchre Cemetery in west Hamilton.
His grave was unmarked until 1967, when the Canadian Club of Hamilton placed a bench and grave marker.

A 360-degree curved plaque was unveiled at Fieldcote Museum in Ancaster on July 20, 2014, marking the 200th anniversary of the most important and largest mass hanging in Canadian history, the execution of nine men convicted of treason during the War of 1812.
This event is known locally as The Bloody Assize.
The men were taken from York, then capital of Upper Canada, and executed near present-day Inchbury Street at the eastern end of Dundurn Park.
Their burial place nearby has not yet been discovered by archaeological research.

A large garden is cultivated near the eastern edge of the park.
The produce is used in the castle's kitchen, and the excess is donated to a local food bank.
Tours of the castle end in the kitchen, where samples of cuisine of the era are offered to tourists.
