Grand Marais

Alger County, USA
🪨Rocks🌀Strong rips🏝️Remote

Grand Marais sits on a remote stretch of Lake Superior's southern shore, where a natural sandbar and breakwall create one of the Great Lakes' most reliable surf setups. The small harbor town is surrounded by the Pictured Rocks National Lakeshore, adding stunning scenery to your surf session. When NW winds push swells into the bay, waves line up nicely with both left and right options. The local scene is small but stoked—this is surfing at its most pure, far from crowds and hype, just you and the lake.
