Summary:
Pebble Beach is a curiously named beach that will make its best effort to twist your ankles. Its “pebbles” are actually large cobblestones of granite, gneiss, unakite, and numerous other oddities. It’s all the usual tumbled treasures you’d find around the shores of Lake Superior, except in much larger form. I highly recommend boots with ankle support as opposed to the water shoes I had to wear in the beginning of the video below.
If you’re brave enough to go out onto the cobblestones at night with an ultraviolet flashlight, you witness special pieces that glow fluorescent orange under fluorescent light. I used a 365nm light in the video below.
There is also a South access that you will see me head towards in the video, marked by the large drainage culvert. You’ll run into a car gate, but there’s an informal parking area there and you just walk around the car gate to a long path down to the culvert.
Important: While this location doesn't appear to be within any protected land, there is a sign asking visitors not to take the rocks. Please be respectful and enjoy the spot without taking any of the tempting, heavy souvenirs.

If I could only bring 3 tools…
Chest Waders
Chest waders were the single best investment I made for exploring the shores of Lake Superior.
Agate Scoop
An agate scoop is helpful for both keeping dry and picking up rocks faster. You don’t need a fancy one. Mine is a golf club welded to a kitchen scoop.
UV Flashlight
There are a few fluorescent rocks at Pebble Beach if you head down there at night. I used a 365nm ultraviolet light to spot them at night.
