The Stone Bridge of Insenborn is a freshwater dive site located in the Lake of Haute-Sûre. This submerged bridge serves as both a wreck and an artificial reef, offering a unique architectural feature for intermediate divers. The site reaches depths between 20 and 30 metres, requiring precise buoyancy control. Divers access the structure via a shore entry. Visibility is variable, typically ranging from 2 to 5 metres, making the use of a primary and backup torch essential for navigation. There is no current at this location, though divers should remain vigilant for boat traffic when surfacing.

The Ruins of Liefrange in the Lultzhausen Area of Luxembourg offers a unique freshwater dive experience across an artificial reef and wreck site. Divers can explore depths ranging from 16 to 30 metres, with an average depth of 17 metres. Visibility is highly variable, fluctuating between 2 and 15 metres. The site presents an overhead environment that requires careful navigation and appropriate certification. Due to the offshore location, a boat is necessary to reach the site. Divers should prepare for cold water temperatures and monitor their depth closely as the wall drops to 24 metres. Parking is available on-site for convenience.
