While Willow Springs doesn't boast the same reliable 30-50 ft visibility that some other local quarries have, it does feature really nice facilities and a full scuba shop. Plus, if you have non-divers in your group they can enjoy the brisk swimming area. Entry into the water is very easy and depths average 30-40 ft. The water is cold, I had 49 degrees at 39 feet in the summer. The visibility was maybe 5 ft but all the attractions were linked together with rope so navigation is easy as long as you have basic compass skills and the map to the various sunken cars and trucks. Viz was so bad at one point that we were on the deck of a boat and didn't realize what it was until we poked around. A great place for low viz practice and to get wet when waiting for a Coz fix. Watch the bottom. It's silty and thick. Great facilities with a full service shop with rentals and sales. Have fun!
