| This is a provincial park well worth visiting with a range of habitats from river/lakeside to mountain with a mix of forested and open areas plus extensive marshlands/swamp.
The park lies on the north shore of Lac des deux montagnes near the confluence of the Ouataouais and Sty. Lawrence rivers to the west of Montreal. To reach it take highway 13 or 15 north to the 640, then head west towards St Eustache. The 640 takes you right into the park. Better yet is to follow autoroute 40 (the Trans Canada Highway), turn off at Hudson and take the ferry over the lake in summer or the ice-bridge in winter. This ferry is quite an experience - nothing fancy, just a large flat barge towed by a small motorboat that races in towards the shore and "slingshots" the ferry at the landing stage while it hurriedly cats off its lines and gats out of the way - fortunately, they are good at this and never miss (yet).
The park has about 30km of trail in all, providing great opportunities for birdwatchers and hikers. There are 3 main trails in the park. The 5.5 km Le Calvaire d'Oka, a historic trail across the hwy from the beach which climbs the parks prominent mountain. Le Sommet is a 7.5km multi-use trail (hiking, biking, and skiing) also on the mountain which offers a fair bit of up and downs. Lastly, L'Erabliere, another loop trail, is 1.5 km in length starting just off the highway in the middle of the park. As a birder you should make a point of taking the Sentier ecologique de la Grande Baie, a nature trail just above the Grande Baie where many of the parks 187 species of birds have been recorded and where many of the parks birds nest. There is a boardwalk leading into the marsh as well as an observation tower. This trail is a 3 km loop and is an easy walk.
The park is especially good for ducks and shorebirds along the edge of the river/lake and for hawks over the mountain.
