TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the Canada Base Map from Natural Resources Canada with Toporama contours layered over it — the CanVec topographic data behind the printed NTS sheets, and the mapping used for hiking, hunting, canoe routes and back-country travel. Relief shows shaded relief and hypsometric tints. The search box finds any Canadian town, county or landmark by name, so you are not limited to La Grand-Mare.
Reading the map like a paper NTS sheet. Click Grid to overlay the UTM grid, labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass — which matters in Canada, where declination runs from about 20 degrees west in Newfoundland to 20 degrees east in the Yukon.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a UTM/MGRS grid reference as well as plain latitude and longitude — the grid reference being what Canadian search and rescue work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

La Grand-Mare is a hamlet in Percé; Le Rocher-Percé, Quebec, Canada. It is classified as a village / hamlet. La Grand-Mare is located at 48.5794°N, 64.3069°W.
La Grand-Mare rests in a quiet embrace where the rugged topography of the coast meets the St. Lawrence, defined by the presence of the Rivière Beattie. It lies 9.4 km north-west of Percé, QC (from Percé, QC: bearing 311°T), and is situated 30.0 km south-south-east of Gaspé. The salt-heavy air clings to the skin as the tide pushes against the shore, and the light at dusk turns the water into a sheet of hammered silver, illuminating the proximity of Le Sugar Loaf. The terrain here holds a stark, singular beauty, marked by the proximity of Parc national de l'Île-Bonaventure-et-du-Rocher-Percé, which stands watch some 14 km away. Life in La Grand-Mare flows with the persistent movement of the Rivière Beattie, a waterway that has long dictated the movement of people and the quiet industry of the shoreline. Residents here maintain a deep familiarity with the shifting moods of the St. Lawrence, their daily routines echoing the persistence of the tides and the seasonal pull of the landscape. While the region is known for the grandeur of the nearby park, La Grand-Mare retains a grounded, solitary character, anchored by the stone and spray of its maritime edges.
La Grand-Mare s’étire avec une patience minérale sur les rives du Saint-Laurent, là où le souffle salin vient caresser les hautes herbes et le sol ferme qui domine les eaux. À proximité du Sugar Loaf, le relief se cabre dans une immobilité ancienne, tandis que les méandres de la Rivière Beattie dessinent un tracé argenté qui semble vouloir rejoindre l’immensité maritime. La lumière du crépuscule dépose sur La Grand-Mare une patine dorée, accentuant la rudesse des falaises et la présence distante du Parc national de l’Île-Bonaventure-et-du-Rocher-Percé, dont la masse imposante veille sur l’horizon à quatorze kilomètres de distance. Le vent, chargé d’embruns, sculpte le paysage en ciselant les arêtes de la terre et en berçant les traces d’une agriculture tenace, héritière d’une longue humilité face aux éléments. Les habitants, habitués à ce climat vigoureux, vivent au rythme des marées et de la rigueur du littoral, trouvant dans cette géographie austère une forme de noblesse. Le silence qui règne autour de la Rivière Beattie renforce le sentiment d’une existence préservée, où chaque pierre, chaque mouvement des courants et chaque inflexion de la côte racontent une histoire faite de patience et d'une sobre persévérance face aux forces grandioses du large.
