Located 10 minutes south of the Wisconsin-Illinois border in South Beloit, Pearl Lake was a former rock quarry. The lake boasts numerous underwater attractions such as sunken boats, an airplane, a submarine, concrete culverts, an underwater buoyancy course, and a bus. Because of these attractions and the numerous underwater training platforms, Pearl Lake is considered one of the best dive training facilities in the Midwest. Other on-site facilities include a restaurant, showers, beach, and campground.
IMPORTANT: All divers must sign in with Aquatic Adventures at the beach house in order to enter the diving area. An entrance fee will be collected a day or two before going to the lake. We will give you a diver pass. You will need to present your pass to the attendant at the diving area entrance. When you have completed your dives, you will return the pass to your instructor before you leave for the day.
