Summary:

This spot had a stunning and vibrant variety of finds. It was one of the most underrated rockhounding spots in the Upper Peninsula. I really hadn’t heard much about it online. You’ll head across a suspension bridge from the parking area to access the Eastern part of the beach. The Western portion can be reached by walking down towards the campground.

Cover up your skin if the stable flies are out in the earlier months of the Summer. They are relentless and seemingly immune to bug spray.

NOTE: There was a $5/day fee to access the parking area when I visited in 2023. I believe it’s cash only - just fill out the little slip and drop it in the box.

3 Helpful 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.

Classifier

A classifier is helpful if you’re a fan of small agates and stones. One with a larger, 1-inch mesh would be what I’d pick.
