This dive site is located in Lake Tiilijärvi, a freshwater lake about 15 minutes from Lahti, Finland. Divers can easily access the site from the shore. Underwater, the main navigational feature is a beautiful grass mat that stretches out for about seven minutes of swimming towards the visible Tiirismaa radio mast. No specific history or complex navigation details are provided for this recreational spot.
The lake is home to various freshwater fish, primarily perch and roach, which can sometimes be seen in large flocks. The most prominent underwater feature is an extensive and beautiful grass mat, providing habitat for smaller aquatic life and adding to the scenic beauty of the dive.
The best time to visit this dive site would be during the warmer months to mitigate the cold water common in Finnish lakes. Divers should note that the area is a recreation zone, so cars must be left in the designated parking lot at the top of the beach, respecting walkers and cyclists. With a maximum depth of 6 meters and an average of 3 meters, it is ideal for snorkeling, freediving, and beginner scuba divers looking for a relaxing freshwater experience.
