Sisjön Badplats

Sweden's west coast is dotted with small inland lakes that the local dive community has quietly made its own, and Sisjön Badplats is one of the best known of the lot. Just a short drive from the Gothenburg ring road, this freshwater lake offers beginner friendly conditions almost year round, which explains why you will often find instructors running Open Water training weekends here. The shore entry is refreshingly simple. You park beside the bathing beach, walk a handful of metres to the water, and descend along a gentle slope that drops away into the main basin. Depths run from a shallow warm up area down to around 15 to 18 metres in the deepest pocket, with visibility typically sitting between 4 and 8 metres depending on algae bloom and recent rainfall. Water temperature is the real variable of the day. In midsummer the top few metres can touch 20 degrees, but drop below the thermocline and you fall abruptly into single digits. Outside of July and August the whole column stays cold enough that a 7mm semi dry or a dry suit is the honest choice for any dive longer than a quick check out. The lake itself is not going to dazzle anyone with megafauna, but that is very much the point. What you get instead is a calm, controlled environment that is ideal for mastering buoyancy, testing a new kit configuration, or running buddy exercises without surge, current or boat traffic. Keep an eye out for pike hovering motionless at the edge of visibility, perch schooling in the shallows, and the occasional crayfish tucked under submerged branches. The bottom is mostly silty, so trim and fin technique matter more than usual if you want to finish the dive in the visibility you started it with. Sisjön Badplats is at its best from late May through early October, when the access road is reliably clear and the car park is in steady use. Bring a thermos of something warm and a towel you do not mind getting muddy, Sweden's changeable skies tend to reward whoever thought ahead.
