Triolago, Lakeside amusement park in Riol, Germany

Triolago is a recreation complex featuring a lake and amusement park set alongside each other, combining water activities with indoor and outdoor entertainment options. The site includes camping areas, lodging choices, dining facilities, and equipment rental services for visitors.

Triolago began in 2003, when a gravel pit on the Moselle bank at Riol was turned into a recreational lake. The leisure park itself opened in 2010, adding a summer toboggan run, a water-ski cable lift, wakeboarding and sports facilities around the three lakes. The site covers about 25 hectares, of which roughly ten are water.

The name Triolago combines "trio", for the three separate lakes, with "lago", Italian for lake. The site grew out of a gravel pit on the Moselle bank at Riol, and the bathing beach, water park and wakeboard facility now occupy the flooded pits. A circular hiking trail runs around the whole grounds, and the Moselle cycle path passes along the riverbank.

The grounds lie in Riol on the Moselle, reached from Longuich via the L145, which ends at a roundabout with parking at the site. A circular hiking trail runs around the whole area, and the Moselle cycle path passes along the riverbank. Riol is connected to the Verkehrsverbund Region Trier public transport network.

The water-ski cable lift is a fixed cable system that tows riders around the lake without a motorboat; the same installation serves wakeboarders. It is one of the park's listed leisure facilities alongside the summer toboggan run, mini-golf and football golf.
