Rega’s Untervaz base is situated in the middle of a nature sports region, which is popular with paragliders in spring, rock climbers and mountain bikers in summer, and hikers and hunters in autumn. It also lies in the vicinity of the Alpine city of Chur.

The history of the Untervaz base

Back in 1976, Rega stationed a rescue helicopter at Bad Ragaz Airport to cover its operational area in Eastern Switzerland. In those days, rescue missions were performed on behalf of Rega by Air Grischa, using an Alouette III with the registration number HB-XDF; already in its first year, the crews flew more than 70 missions. From autumn 1980, Rega operated its base in Bad Ragaz for the first time using its own staff. In 1982, Air Grischa and Rega inaugurated a new joint base, complete with hangar, in Untervaz. From then on, the rescue helicopter from the new Graubünden base took off from Untervaz.


August 1992 marked the beginning of a new Rega era at the northern Graubünden base. The first of the new, twin-engine Agusta A 109 K2 rescue helicopters commenced operations in Untervaz. The growing number of missions soon called for larger facilities, and in 1998 a more spacious building was constructed. In November 2009, the Untervaz base took delivery of the new mountain helicopter, the AgustaWestland Da Vinci, bearing the registration number HB-ZRW. Nowadays, the crew at the Rega base in Untervaz flies more than 1000 missions each year. The majority of these involve winter and summer sport accidents of all kinds.
