This dive site, known as U-Boot, features a unique attraction: a complete submarine wreck, approximately 6-10 meters long, resting at a depth of about 55 meters. Access to this fascinating wreck is conveniently from land via Camping Grabner in Pike Bay. Due to the significant depth of the wreck, a dive without a scooter typically takes around 15 minutes to reach the target. While the site's stated maximum depth for general recreational diving is 25 meters, the primary feature requires reaching a much greater depth, making it a challenging dive.
The marine life at this freshwater dive site is relatively sparse compared to tropical reefs. Divers can expect to encounter small perch and a few crabs, but the main draw is undeniably the man-made structure of the submarine rather than a rich ecosystem.
This dive site is strictly recommended for experienced divers and technical divers due to the depth and nature of the wreck. There is no specific best time to visit mentioned, but lake diving in Austria often means colder water, so appropriate thermal protection is advised. While the official site depth is 25 meters, accessing the submarine at 55 meters requires specialized training and equipment, making it unsuitable for casual freedivers or snorkelers.
