Main Beach on the west side of Rondeau and Erieau features a vast sandy-bottomed area with a very gradual drop-off. This freshwater site is accessible via shore entry, though divers should be prepared for variable conditions including strong currents, surf, and periods of low visibility. Water temperatures fluctuate significantly throughout the year, ranging from 1C in the winter months to 23C in August. Due to the challenging environmental factors, this site is rated poorly for snorkelling. Facilities available at the location include parking, toilets, and showers.

Erie Rest Beach offers a shallow freshwater shore entry suitable for beginners. The site features a transition from sandy areas to a rocky clay bottom, particularly toward the western edge near the bluffs. Depths typically range from 1 to 5 metres, with an average of 3 metres. Visibility varies between 3 and 10 metres, and currents are generally mild, though divers should be aware of potential rip currents and strong currents in the area. Facilities at the site include parking and toilets. Water temperatures fluctuate significantly throughout the year, ranging from 1C in February to 23C in August.

Fuhrman's Cave is a freshwater site located along the rocky bluffs near Rondeau and Erieau. This site features a shallow underwater cave and rock formation, which is a rare structural feature for the area. Divers can expect depths ranging from 2 to 12 metres, with an average depth of 7 metres. The site is accessed via a shore entry and is suitable for intermediate divers. Visibility typically fluctuates between 3 and 6 metres. Hazards include cold water temperatures and surf conditions. Facilities available at the site include parking and showers. Typical dives last approximately 30 minutes.

Port Bruce West Pier offers a freshwater snorkelling experience focused on the artificial reef created by the pier's vertical pilings and rock reinforcements. Located in the Great Lakes and Ontario, this site provides a more varied habitat than the surrounding open beach. Snorkellers should be prepared for depths ranging from 3 to 7 metres, with an average of 5 metres. Conditions at this shore-entry site are variable, featuring strong currents, surf, and low visibility. Due to these environmental factors, the site is best suited for intermediate-level snorkellers. Facilities available at the location include parking, toilets, and a cafe.

The Nimrod is a freshwater wreck located in Lake Erie, resting at depths between 10 and 19 metres. Access to the site is exclusively by boat charter. Divers encounter moderate currents, particularly around the vessel's superstructure. Visibility at the site fluctuates between 5 and 18 metres. Due to the overhead environment and potential for entanglement, this site requires careful buoyancy control and the use of a torch. Water temperatures at depth remain consistently cold, typically ranging from 3 to 9 degrees Celsius throughout the summer months. Divers should be prepared for cold-water conditions and possess appropriate thermal protection.

Gold Coast Shipwrecks in the Great Lakes region offers a challenging freshwater wreck diving experience at depths between 20 and 40 metres, with an average of 30 metres. The site features a wreck structure accessible from the shore, though divers must navigate potential surf and rip currents during entry. Conditions vary, with visibility ranging from 5 to 20 metres and mild currents. Water temperatures fluctuate significantly from 1C to 23C, requiring appropriate thermal protection such as a drysuit for most of the year. Due to the depth, cold water, and potential for entanglement or low visibility, this site is suited for intermediate divers who should carry redundant lighting.

The Merida is a freshwater wreck located in Lake Erie, resting at depths between 18 and 24 metres with an average of 21 metres. This site is accessible by boat only, situated 40 kilometres from shore. Divers encounter visibility ranging from 5 to 6 metres. The environment features a thermocline around 15 metres, with surface temperatures reaching 24C in summer and bottom temperatures averaging 10.6C. Due to the depth, cold water, and potential for entanglement within the structure, this site is suited for intermediate divers. Proper gas management and buoyancy control are essential, and a drysuit is recommended outside of the warmer summer months.
