Explore Finland

Diving in Finland offers a unique and exhilarating experience for adventurers seeking something different. Unlike tropical dive destinations, Finland's underwater world is defined by its cold, clear waters, providing an unmatched opportunity to explore historic wrecks and vibrant marine life. The Baltic Sea, with its brackish waters, is home to some of the best-preserved shipwrecks in the world, dating back to the medieval era. These underwater time capsules offer a fascinating glimpse into maritime history, attracting divers from around the globe.

Finland's diverse dive environments include tranquil lakes and the striking geology of its coastline, where divers can explore underwater cliffs and rock formations. Shore diving is popular due to the ease of access to these sites, while boat diving unlocks remote spots teeming with life. Seasonal changes dramatically alter the underwater landscape, with the summer months providing extended daylight hours for longer dive excursions. Winter diving reveals a surreal experience, with ice diving offering a unique challenge for the adventurous.

Courses and Events

Deep Diving

The SSI Deep Diving Specialty course will teach you everything you need to dive to depths of 18-40 meters safely. Diving deeper requires special skills. The course goes through in theory and practice what things should be taken into account in deeper dives. The course examines, among other things, how the increasing pressure as you go deeper affects the planning of the dive, air consumption and the diver himself. The course consists of online learning material, contact teaching, a theory test and three training dives. After completing the course, you will receive a Deep Diving classification, which allows you to dive up to 40 meters. The basic education requirement is the OWD classification and the age of 15 years. The SSI Deep Diving course has a lot of benefits from the SSI Enriched Air Nitrox 40% rating, and if you don't already have the Nitrox course, it's convenient to combine it with the Deep course. In addition, we recommend that you have taken the SSI Dry Suit Diving Specialty course or at least have good skills to dive with a dry suit. You'll learn how to plan and execute your deep diving adventures safely, as well as how to use computers and gas consumption calculations to get the most out of your deep dives. Upon completion of the course, you will receive an SSI Deep Diving Specialty certificate and will be able to explore beautiful deep dive sites wherever you are. This SSI specialty course is also a prerequisite for some advanced training, so it is the next logical step in your diving training. The course dates will be agreed together.

Top Wildlife Sightings in Finland

In Finland, freshwater divers can encounter an array of wildlife, including pike, perch, and zander. These species are commonly found in lakes and rivers across the country. During spring and early summer, divers might witness the vibrant activity of spawning fish, particularly when water temperatures rise and visibility improves. Noteworthy sightings include the elusive catfish and sturgeon, generally found in deeper waters. Visibility in Finnish waters varies, often clearer in colder months when algae growth is minimal. Planning dives in autumn can offer better sightings due to increased water clarity and cooler, stable temperatures.
