Mulgrave-et-Derry, Quebec: History, Things to Do and Travel Guide
Mulgrave-et-Derry is a large, sparsely settled municipality in Quebec’s Outaouais, in the MRC de Papineau. Its travel identity comes from hills, forests, more than a hundred lakes, seasonal cottages, fishing, snowmobile routes and the old township geography of Mulgrave to the east and Derry to the west.
How Mulgrave-et-Derry Started
The Commission de toponymie records Mulgrave-et-Derry as a municipality formed from two united townships in 1870. The name comes directly from the two township entities that were joined. Mulgrave may refer to British figures associated with the Mulgrave title, while Derry recalls the Irish county and city name.
The municipal coat of arms page gives the local settlement story a clearer visual frame. It says the community was founded in 1870 mainly by German and Irish immigrants, and that several families descended from those pioneers still live there. The green, gold and blue colours of the arms represent Irish, German and French origins, as well as the area’s forests, minerals and lakes. In 2003, the former status as a united-townships municipality was changed to the present municipality of Mulgrave-et-Derry.
What Mulgrave-et-Derry Is Like Today
Mulgrave-et-Derry had 461 residents in the 2021 census, spread across a large territory. The municipality describes itself as the second-largest territory in the MRC de Papineau, covering 317 square kilometres and containing at least 130 lakes. The municipal office is at 1 chemin de la Montagne, and the website is important for road, lake, waste, fire, public notice and library information.
The place has two practical travel faces. Mulgrave, to the east, is reached by route 315, while Derry, to the west, is reached by route 309. Summer residents can double the population, so a road that feels very quiet in April can feel much busier around lake access, cottages and fishing in July.
Things to Do and Places Nearby
This is primarily an outdoor municipality. The coat of arms page names fishing, ATV riding, snowmobiling, hills and forest as part of the local character, and the wavy lines in the arms represent lakes, rivers and snowmobile tracks. Plan activities through current local rules, because much of the shoreline and many access roads are tied to private property or seasonal residents.
For a community stop, look for the municipal library and Réseau BIBLIO branch at 941-A chemin de la Mine. The municipal site also points to the Société d’histoire de Mulgrave-&-Derry and Club Les Voyageurs des Collines et Ravins, useful local anchors for people trying to understand the heritage and outdoor culture without treating the municipality as only cottage country.
Short visits work best as scenic drives on routes 315 and 309, lake-country errands, a library or community event, and a careful look at posted municipal notices.

Travel Notes
Do not assume every lake road leads to public water access. Check municipal notices, fire conditions, cyanobacteria advisories, road maintenance and waste-site rules before planning a lake day.
Cell service and services can be uneven in the hill country. Carry the basics, watch for gravel and winter conditions, and give more time than the map suggests when crossing between the Mulgrave and Derry sectors.
