Of the rest of the land, 3.6% is settled (buildings or roads) and the remainder (33.9%) is non-productive (rivers, glaciers or mountains).

The main river is called Flem while Caumasee and Crestasee to the south of the town do not have tributaries for lying in the debris area of prehistoric Flims Rockslide, where the landscape is very rough and completely forested as there was no agriculture possible ever.

The easiest access to the area is an aerial cableway to Fil de Cassons from Flims or any of various hikes to this ridge lying southeast of Piz Dolf.

The small, quiet village was traditionally a winter home for dairymen whose animals grazed on the lush green slopes of summer.

Ancient Flims was populated since the Bronze Age, the remains of a medieval castle (Burg Belmont) can be reached by foot from the end of the public road at Fidaz within 40 minutes.

Originally growing as a summer spa town in a distinctly wind sheltered and wide open area, especially since the building of big Hotels from 1877 on, it is nowadays also famous for winter sports (mainly skiing and snowboarding) and is now part of the Weisse Arena resort which combines the formerly separate resorts of Flims, Laax and Falera.

It is regular host to international competitions such as the FIS World Championship in skiing and the Burton European Open in snowboarding.

Due to the easy access the Weisse Arena cable-cars provide to the mountains, the town has become a popular winter and summer tourist locale.

Today Flims is a year-round resort popular not only with winter sports of snowboarding, cross country skiing, downhill skiing and sledding, but also summer sports including hiking, rock climbing, paragliding, mountain biking and swimming in Caumasee, a spring-fed, iridescent-blue-water lake.

The area of Conn is a good point of view over the Ruinaulta (Rhine gorge), an impressive rafting and canoeing aera.

Skaters who have been regulars at the camps include Swiss national team members Jamal Othman, Sarah Meier, and Stéphane Lambiel, as well as international skaters Evan Lysacek, Gregor Urbas, Karel Zelenka, Kiira Korpi, and Ari-Pekka Nurmenkari.
