Even though Keystone is a small park it still has lots to offer. There are three dive sites on this one location. First is the Jetty, second is the pilings, and third is the drift dive. One thing people do when they come here is go to Octopus hole and nothing else. They miss so much more around 15 feet. Next time you go diving try staying at 20 to 30ft and go to the end of the jetty and I promise you, you will see a lot more than you think was there. If you into micro this is a great place to come and practice your skills, current sometimes is an issue. But, if you take care to watch them you will have a great dive. The Drift dive is more advanced, but it's fun to do when the currents are just right. Just remember there is lots to see from 10 to 25 feet range. Don't go to the bottom and spend all of your time there. The Keystone Jetty has lot to offer from the novice to the advanced.
