S-chanf is one of the pedestrian gateways into the Swiss National Park, as it is near the confluence of the Val Trupchun, a pedestrian only area of the park, and the Engadin. In the park, early risers may spot marmots and, high on the mountains, Steinbok (ibex). It has at least two hotels: the Aurora and the Scaletta.

S-chanf is the final destination of the "Engadin Skimarathon", a popular cross country ski race over marathon distance, which starts in Maloja.

The twin homes and barn at Nrs. 216/217 and the home with barn at Nr. 107 are listed as Swiss heritage sites of national significance.

S-chanf is the home to a base of the Swiss Air Force, which maintains one of its antiaircraft target shooting ranges (serving also as finish area of the "Engadine Ski Marathon") in that area.
