Southern Maryland Divers visits the fresh water rock quarry Lake Phoenix one weekend a month starting in April and running through October. This is the location where Open Water students will complete their certification dives. We also teach other classes to include the PADI Advanced Open Water Class as well as other specialty classes at this location as long as the dives can be completed within the standards set forth by that course. You can schedule your diving by contacting the shop. Click HERE to checkout a FAQ about our quarry weekends.
