From June through September, daily boat trips run from Ilulissat harbor out into Disko Bay among the icebergs. The experience of drifting past icebergs the size of city blocks — blue-white and groaning with the stress of their own weight — is one that simply cannot be replicated anywhere else accessible to ordinary travelers.
Several operators run three to four hour trips, and whale watching is a standard component from July onward. Bring waterproofs regardless of the weather — the spray off the water is cold even in midsummer — and layers. The harbor is right in town; operators set up near the dock.
