Twin Rocks is a shore accessible salt water dive site, located in Brookings, OR.
Another quintessential Oregon Coast diving site, also known as Lone Ranch. The facilities include picnic tables and restrooms, and, on a sunny day, you can’t beat the beachcombing! You’ll find the best diving to the North, after a short kick to the deeper water.Directions: About 4 miles North of Brookings, you’ll see the beach area and the turn off.
A lot of sandy bottom straight out. Relatively light population of fish, but a good variety. DO NOT attempt to go around the North end if there is any surge or wave action. Safest entry is from the beach by the creek, then swim a lot. The rocks are very slippery, and going at high tide allows entry over them by swimming.
