There are 3 destination agencies in Greenland: in East Greenland, South Greenland and North Greenland.
The destination agencies work with development of tourism in the regions, such as marketing, education, business development, product development and improvement of infrastructure. The agencies are able to provide you with neutral information on excursions, tour operators and accommodation. The agencies are therefore not tour operators, but part of the local administration, and the staff are public employees.
