Järppilän louhos - Baltic Coast

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.
