Pursuant to section 3(2) of the Executive Order on Travel, a permit is required for sailing in the area referred to in section 1 of the Executive Order, regardless of the duration of the trip. In practice, this means that cruise vessels and other vessels sailing closer than 3 nautical miles from the baseline of the National Park in North and East Greenland must have an expedition permit before they sail into the area. This applies whether or not the trip lasts less than 24 hours.
No permit is required for ordinary traffic and travelling on the occasion of usual fishing and hunting activities in the areas listed in section 1 of the Executive Order on Travel and carried out by persons permanently residing in Greenland, cf. section 4 of the Executive Order on Travel.
