Opeongo Lake (Access Point #11) is Algonquin's largest and most imposing lake—58 km² of open water demanding respect and caution from paddlers seeking remote interior access. The lake's vastness provides gateway access to legendary northern routes via portages to Happy Isle, Redrock, Merchant, and Crow River systems; water taxi services mitigate the dangerous paddle across Opeongo's notorious headwinds. Experienced paddlers praise the raw beauty and wilderness solitude of northern lakes, while cautious adventurers appreciate taxi shuttles eliminating the risky crossing. The 15km shoreline offers island-hopping and scenic arms with red gravel beaches; expect 4-5 day minimum for a north-of-Opeongo experience, wind delays, and challenging conditions requiring strong paddling skills and good judgment.
The difficulty of Access 5 (Opeongo Lake) River varies by section.
The best time is June-September.
Access 5 (Opeongo Lake) River is located in the Algonquin Provincial Park region of Canada.
