Kayaks for hire are also available in Ammassalik, Nanortalik, Qaqortoq and Aasiaat, while Kangaatsiaq, Nuuk, Kangerlussuaq and Disko Bay should have kayak rentals soon, if not already. Kayaking in Greenland is not for the novice. The weather can change very quickly, and powerful winds can make the steep coastlines unapproachable. In fjord estuaries and straits, there can be strong currents. Finding your bearings in dense fog in skerries and fjords can be particularly tricky, and even in the most unlikely places there may be hidden rocks.
Icebergs can tumble, glaciers can calve.
You should know what you're doing. Even experts hire guides. Most anglers are primarily interested interested in sea-going mountain trout, which is found in virtually all rivers and water systems in Greenland. Sea trout migrate out to sea in springtime and return in late summer. The return may extend over several months in the larger rivers to just a few days in the smaller ones.
