Judith-De Brésoles Ecological ReserveRéserve écologique Judith-De Brésoles
Go only if you are already at Lac-Édouard: this is a 10.9 km² research reserve with no gate, no facilities and no published entry fee — a half-day walk on one rough route, not a destination in itself (access and staffing: check).

- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- Canada ↗Visa-exempt travellers flying to or through Canada usually need an eTA; check your passport on the official Government of Canada site (canada.ca) and apply only there.
- Canada ↗A Parks Canada pass is needed to stop in national parks such as Banff and Jasper; some spots (for example Moraine Lake) are reached only by shuttle or tour, so book ahead.
- Canada ↗Keep well away from bears, elk and moose; carry bear spray on Rockies trails and follow trail closures.

Judith-De Brésoles Ecological Reserve is a 10.9 km² provincially managed scientific reserve in the Laurentian hills southwest of Lac-Édouard, in the Mauricie region of Quebec. Created in 1992 and named for Sister Judith Moreau de Brésoles, founder of the Hôtel-Dieu hospital nuns in Montreal, it protects fir and yellow birch forest on the Canadian Shield, a sugar maple–yellow birch stand at the northern limit of its range, and Lac Mauvais. There is no gate, no staffed entrance and no published fee. A single rough trail runs from the railway on the south side of Lac-Édouard along rue Damasse and the east shore of Lac Édouard, rounding a hill near the outlet of Lac Aval at about 440 m. It is a half-day walk for people already staying at Lac-Édouard or La Tuque, not a stand-alone destination, and it pairs with the much smaller Bog-à-Lanières reserve for a two-stop nature day.

Accessibility
- There are no paved paths, boardwalks, railings or accessible toilets anywhere in the reserve.
- The trailhead is reached by an unpaved road; the walking itself is rough and not suitable for limited mobility.

- This is a scientific reserve first: keep to existing lines of travel and do not widen the path.
- Pack out everything, including food scraps, since there are no bins or facilities.
- Report wildlife sightings to the managing ministry rather than posting precise locations of sensitive species.
Questions people ask
How much does it cost to enter Judith-De Brésoles Ecological Reserve?
No entry fee is published for this reserve, and Quebec ecological reserves are generally unstaffed with no ticket desk (check). You walk in from rue Damasse at the northern boundary. Budget for fuel, food and lodging in Lac-Édouard or La Tuque instead.
What are the best hikes in Judith-De Brésoles Ecological Reserve?
There is effectively one route: the trail that begins at the railway on the south side of Lac-Édouard, follows rue Damasse along the east shore of the lake, rounds a hill near the outlet of Lac Aval and continues south along Lac Édouard. It is rough and unmarked, and no official length or walking time is published (check). A shorter walk from the northern boundary toward Lac Mauvais is possible but has no path.
When is the best time to visit Judith-De Brésoles Ecological Reserve?
June to September is the practical window, with September usually the driest and the birch turning in late September and early October. June has the longest days but the worst blackflies. From November to April snow and freeze-up make the reserve impractical; winter access is unverified (check).
Do I need a permit or a guide?
No permit and no guide are documented for walking in. Any research, sampling or collecting needs written authorisation from the Quebec ministry that manages ecological reserves. Motorised vehicles, bikes, horses, camping, fires, hunting and fishing are prohibited inside Quebec ecological reserves (check).
How do I get to Judith-De Brésoles Ecological Reserve?
Drive to Lac-Édouard, about 60 km by road from La Tuque on route 155 and Chemin du Lac-Édouard; driving times from Montreal and Quebec City are unverified (check). From the village, take rue Damasse south-west, cross the railway and continue about 2.8 km to the northern boundary. VIA Rail's Montreal–Jonquière train serves Lac-Édouard and can stop at the reserve on request — confirm when booking.
Is it the same as Bog-à-Lanières Ecological Reserve?
No. Bog-à-Lanières is a separate, much smaller reserve of about 4.3 ha south-east of Lac-Édouard village. Both are unstaffed Quebec ecological reserves and they combine well into one day.
