This dive site, Schloss Heroldeck at Millstätter See, offers a unique freshwater diving experience with easy shore access via a sturdy ladder. Located directly below the Heroldeck Castle on the B98, it features a prominent rocky shore that drops steeply to 10 meters. Divers can explore interesting rock formations, submerged tree trunks, and dense aquatic vegetation, particularly vibrant in the 0-15 meter range. A notable feature is a rowboat found at 5 meters after about 15 minutes of dive time, adding an intriguing point of interest.
The vibrant aquatic ecosystem is home to diverse freshwater flora including milfoil and hornwort, which provide extensive habitat for numerous fish species. Divers can expect to encounter pike, perch, tench, rudd, roach, catfish, and zander, especially in the areas with dense vegetation. The abundant fish life and plant structures make this a rich environment for observation.
While specific seasonal highlights are not mentioned, freshwater lakes in Austria are generally best visited during warmer months when water temperatures are higher and visibility potentially better. The site is suitable for both scuba divers and freedivers, with interesting features accessible from the surface down to 24 meters. Divers should be mindful of the steep entry and exit via the ladder. The shallower areas are particularly rewarding for macro photography and fish spotting, while deeper sections offer a glimpse into the lake's unique topography.
