Titlis Rotair, Revolving aerial tramway in Engelberg, Switzerland.

Titlis Rotair is a modern cable car that rises from Engelberg to approximately 3,020 meters (9,911 feet) and completes a full rotation during the journey. The transport system consists of three interconnected cable car sections providing access to winter sports facilities, a glacier cave, and a suspension bridge.

The first cable car section from Engelberg to Gerschnialp opened in 1927, and the line was extended to Trübsee in 1938. The final stretch to the summit, built in 1967, was the world's first revolving aerial cableway, the Rotair. A later rebuild replaced the original cabins with larger rotating ones, and the system now runs in two sections from Engelberg via Trübsee to Stand.

The cable car is named Rotair for its rotating cabins, a principle that lets every passenger face outward without moving. At the summit station, a glacier cave cut into the ice of the Titlis glacier can be walked through, and the Titlis Cliff Walk suspension bridge crosses a gap above the glacier.

The ride operates year-round with different activities available depending on the season. Visitors should bring warm clothing since it is significantly colder at the summit than in the valley.

The rotating cabins were introduced in 1992 with the opening of the Engelberg–Titlis section, making it the world's first revolving aerial cable car. Each cabin holds 80 passengers, and the floor turns with the cabin so riders circle past the Titlis glacier and the Bernese Alps without leaving their spot.
