Established in 1910, it is 118 hectares (290 acres) in size, with 38 hectares occupied by the Montreal Botanical Garden and Montreal Insectarium, 55 hectares (140 acres) by a nine-hole public golf course and the remaining 25 hectares (62 acres) hectares by public spaces. Originally the park contained an 18-hole golf course which was reduced to 9 holes in the mid-1970s in order to construct the Montreal Olympic Park.
Maisonneuve Park borders partially on Sherbrooke Street East.
It is named in honour of Paul Chomedey de Maisonneuve, founder of Montreal.
The park is a unique place where people enjoy walking day or night, bicycling on its bike trail which runs all the way around the park. The center of the park is a calm area where people enjoy picnics and tranquility and is very popular among young people and families.
The loop section of the bicycle path is 3.1 kilometres (1.9 mi) long. This does not include the path outside the fenced area, along Sherbrooke St.
It has been the site for Montreal's annual Fête nationale du Québec concert on June 24, but in 2015 the festivities were held in the Place des Festivals instead.
