Lago de Panticosa is a high-altitude freshwater site in Spain, primarily utilised for ice diving during the winter months. Divers access the water from the shore to explore depths reaching 20 metres. The site is characterised by its extreme cold, with water temperatures frequently dropping below 3°C. The primary experience involves navigating beneath the ice, where light creates unique visual effects through the frozen surface. Due to the cold water and the overhead environment, this site is suitable only for advanced divers with specific ice diving training. Dives typically last around 20 minutes.

Lake of Piau-Engaly is a shallow, shore-entry freshwater site in the French Pyrenees. Divers typically experience depths ranging from 1 to 5 metres, with an average of 3 metres. The site offers visibility reaching 30 metres and calm water conditions, making it suitable for beginners to practise buoyancy and technique. Due to the cold water temperatures, which can drop to approximately 3°C during ice diving, adequate thermal protection such as a drysuit is essential. Divers should remain aware of the overhead environment and avoid entering caves or swim-throughs unless specifically trained for such conditions. On-site facilities include changing rooms, toilets, and air fills.

Plongeoir on the Basque Coast of France features a combination of natural and artificial reef structures. The site is accessible from the shore and experiences mild currents, making it suitable for beginners, though depths range from 5 to 35 metres with an average of 20 metres.

Facilities on site include showers and a rinse station. Night diving is permitted at this location. Divers are advised to wear hard-soled footwear to protect against hazards present throughout the reef area.
