Järppilän louhos
Why dive here
With 50+ marine species recorded in the area - including dwarf minke whales and jellyfish lake - Järppilän louhos offers some of Baltic Coast's richest diving. Water ranges 1-17°C, warmest July, August, September.
Järppilän louhos is an old quarry, now freshwater filled, making it a reliable spot for training dives or simply getting in the water when coastal conditions are rough. It’s pretty shallow, topping out at 15m, with decent visibility if you’re the first in. We’ve spotted perch and pike here, sometimes even a crayfish if you look closely. It's a calm, easy dive for beginners or a good place to test new gear.
