We enjoyed the dive. It's in a nice park in the trees with a long rocky beach, and you'll likely be the only divers there; it's not popular as IT IS A LONG FIN-SWIM, maybe 20 to 25 minutes, guessing 1,500 to 2,000 feet entering at the footbridge and swimming to the buoys at 036 degrees. Typically, the visibility is 5 to 20 feet and the current negligible. The barge structural elements are full of life, different nudibranch varieties, sea pens and sea stars, plumose and swimming anemones, different crab varieties everywhere you turn, and striped sea perch. We didn't see the octopus or wolf eels reported here, but the habitat looks right.
It's about 12 miles from Olympia. From I-5, take Exit 111 - Marvin Rd, it tees into 56th Av - go right on 56th, at the park entry take the left fork down a hill to parking near the water [about 100 yards walk to the beach]. The park day use fee is $5. [closed Mon.Tue]
