Mystery Lake Scuba Park is a freshwater artificial reef site in the United States. Divers access the water via a shore entry for dives typically lasting 45 minutes. The site reaches a depth of approximately 12 metres. Conditions vary significantly throughout the year, with summer water temperatures reaching 28.9°C and winter temperatures dropping to 10°C. Divers should be prepared for cold water and distinct thermoclines, which can make deeper sections chilly even during the summer months. On-site facilities include parking, toilets, and changing rooms, with guided tours available for those who require them.

Water World Marine is a shore-entry reef site in Florida suitable for new divers. The reef is located in shallow, calm water, providing a comfortable environment for building confidence and practising buoyancy. Because currents are variable, divers should check conditions before entering. Visibility can fluctuate, so arriving early in the day may offer clearer water before surge or boat traffic stirs up sediment. The site features comprehensive facilities, including parking, toilets, showers, changing rooms, a rinse station, air fills, equipment rental, and boat charter services. The habitat supports a variety of reef fish and invertebrates typical of the region.
