Diving Wörthersee
Site Overview
Wörthersee is a alpine lake dive site in Carinthia, Austria, set among the country’s varied freshwater landscapes. Wörthersee is Austria’s warmest large lake, a glamorous Carinthian basin with extensive, varied diving. Its sites include the Pörtschacher Wall, the Maria Wörth reef and the Reifnitzer Platten plateaus. Wrecks are the headline: a sunken small aircraft, a DC-3 / C-47 transport fuselage and several wooden wrecks. Large pike and carp roam the clearer water, and the warm surface makes for comfortable dives. It is one of Austria’s best wreck-diving lakes while still offering easy bays for training. A drysuit is advised below the thermocline, but the warmth makes it forgiving for a big lake. Conditions are typical of Austrian inland water: visibility generally runs from 8 to 22 metres, the current is low and the water temperature ranges between 6 and 27 degrees Celsius depending on season and depth. The marine life is freshwater and centred on northern pike, common carp, european perch, with the full community described below for those planning a dive. Because of its intermediate rating and the need for Advanced Open Water certification, Wörthersee is best approached with the right thermal protection and, where relevant, altitude or overhead training. It is a representative example of why Austrian lake diving, with its cold clarity, submerged forests and wrecks, attracts divers who want something different from tropical reefs.
Dive Briefing
"Entry is made from the shore near Velden, and divers should check in with a local centre before entering the water. Wörthersee is Austria’s warmest large lake, a glamorous Carinthian basin with extensive, varied diving. Its sites include the Pörtschacher Wall, the Maria Wörth reef and the Reifnitzer Platten plateaus. Wrecks are the headline: a sunken small aircraft, a DC-3 / C-47 transport fuselage and several wooden wrecks. Large pike and carp roam the clearer water, and the warm surface makes for comfortable dives. Plan your profile around a maximum depth of 40 m and an average of 18 m, keeping a close eye on gas and, in deeper sections, on the cold thermocline. Buoyancy control matters: silty or vegetated bottoms and submerged structures are easily disturbed, and entanglement on wrecks and wooden structures is a real consideration here. A safe ascent with a surface marker buoy and a clear exit plan completes the dive, with emergency cover routed through Klagenfurt State Hospital."

Traveler Notes
Who is this for?
Wörthersee suits intermediate divers holding at least an Advanced Open Water certification, and it is a strong choice for those who enjoy cold-water, freshwater environments. Photographers, training groups and divers chasing wrecks, walls or macro life will all find something here, provided they respect the temperature and the limits of an inland lake. It is less suitable for absolute novices unless booked through a centre running a supervised course, and overhead or very deep sections should only be attempted with the correct specialist training.
