Hike to Grandma's Cove

Grandma's Cove at high tide

NPS

Grandma’s Cove is a great place to go for a swim! The water is shallow and protected, making it safer and warmer than other beaches on the island. While exploring the shoreline, you might see anemones, tide pool sculpin, mussels, shore crabs, barnacles, and a variety of seaweeds. Visitors often find sea glass too!

If you’re interested in a hike, the mile long round trip to the cove is of moderate difficulty. Along the way you can see the remains of Robert’s Redoubt. You might also spot bald eagles, foxes, or rabbits.  

To get to Grandma’s Cove, you should park at the American Camp Visitor Center. Take the westernmost trail to the Parade Ground and shortly after leaving the parking lot a marked trail to Grandma’s Cove will be on your right. From there you will walk 5-10 minutes downhill on a grassy trail with expansive ocean views and then you’ll reach the beach!
