Six days is the classic Svalbard summer week, long enough to put several days on the water, stand at a glacier front, read the wildlife coast and still walk the tundra, without packing the schedule tight.
You stay in Longyearbyen throughout and head out from town each day. Five nights give your guides real room to manoeuvre: when a morning comes in grey, they can move the plan and still catch the calm water later, because under the midnight sun the day never really ends.
Nothing here is artificial. Wildlife is wild and the weather decides the order of things, so the week flexes around what the Arctic is doing. What we promise is the time, the people who know the ground, and an itinerary built around your dates.
