Rantaharjun loma is a freshwater wreck and artificial reef site located in Finland. The site features structures situated between 9 and 17 metres, with an average depth of 13 metres. Accessible via a shore entry, it is suitable for beginner divers as there is no current to manage. Visibility typically ranges from 5 to 10 metres. Due to the freshwater environment, cold water is a primary hazard, and proper thermal protection such as a drysuit is recommended for all dives. Typical dive times are around 40 minutes. Divers should confirm facility availability with the site operator before arrival, as amenities can be limited.

Saajuu is a freshwater reef site located in Finland, offering a depth range of 6 to 30 metres. Accessible via a shore entry, the site features mild currents and visibility typically ranging between 5 and 15 metres. This location is suited for intermediate divers. Due to the cold water temperatures common in Finnish lakes, a drysuit or thick wetsuit is recommended throughout the year.

Exercise caution near the reef structure to avoid contact with rocks and maintain neutral buoyancy to protect the seabed.
