About 35 miles northeast of Grand Marais, just before the road reaches Grand Portage, there's a small turnoff for County Road 89. Follow it down to the shore and you'll find a pebbly Lake Superior beach with a natural rock arch sitting just offshore. That's Hollow Rock. It takes roughly an hour from Overlook Hus to get there. No trail, no fee, no permit. Just park and walk to the water.
What It Is
Hollow Rock is a sea stack, a remnant of the shoreline left standing after the surrounding rock eroded away. The arch at its center formed over centuries from wave action. Lake Superior does not move gently. The rock is basalt, part of the same volcanic geology that defines the entire North Shore, lava that cooled at the surface 1.1 billion years ago when North America nearly split in two. The fact that any of it is still standing is its own kind of story.
The formation sits just offshore, close enough to feel immediate from the beach. When the lake is calm, the reflection is clean and still. When the wind is up and waves are moving, the water pushes through the arch and the scale of the thing becomes obvious.
Getting There
The beach sits at Hollow Rock Resort at 7422 Highway 61 in Grand Portage. You do not need to be a resort guest to access it. The beach is public. Turn off Highway 61 onto County Road 89, follow it to the shore, and park near the water. The walk from the car to the rock takes about two minutes.
From Overlook Hus in Tofte, the drive is approximately 55 to 60 minutes northeast on Highway 61. It passes through Grand Marais, which makes a natural stop in either direction for coffee at Crosby's Bakery or a meal at the harbor.
Best Time to Go
Hollow Rock faces east over the lake. Sunrise is the obvious answer, and it earns it. The light comes across the water at low angles and hits the arch directly. On a clear morning the color can be vivid and it doesn't last long.
That said, it photographs well in any light. Storm light, flat overcast, late afternoon from the north side. The formation is distinctive enough that the camera finds it regardless of conditions. In winter, when ice forms along the shoreline and snow collects on the rock, photographers drive hours specifically for the combination.
Every season produces something worth seeing. The wildflower season around the resort grounds in late spring. The deep blue of the lake in July. The color reflected in the water during early October. The ice formations from January through March.
What Else Is Nearby
Grand Portage is another few miles up Highway 61. Grand Portage State Park is there, with the High Falls of the Pigeon River, Minnesota's tallest waterfall at 120 feet, a short walk from the parking lot. Grand Portage National Monument, which preserves the historic fur trade depot of the North West Company, is also in the area.
If you're making the drive, the combination of Hollow Rock, the High Falls at Grand Portage State Park, and a stop in Grand Marais on the way home makes a full day with almost no planning required.
The Drive Itself
Highway 61 from Grand Marais to Grand Portage is one of the best stretches of road on the North Shore. The Sawtooth Range drops toward the lake, the road stays close to the water, and there are almost no traffic lights. It's the kind of drive where the scenery is the point, not just the backdrop.
Hollow Rock is the destination at the end of it. But the drive is half the reason to go.
