No. 5 trips are our most demanding trips. They are long and have many or all nights in tent. You must expect to work hard for a long time to reach the goal. The tours are physically, and mentally demanding, and good preparation is required to participate.
Some of the challenges you can meet is wind, snow, rain, whiteout, cold, emergency camp for a while, heavy carrying or pulling, every day setting up a new camp, as well as time schedule for breaks and progress.
You should have experience from one or more trips on level 4, and a lot of determined training is required in advance of the trip. The equipment plays an important role, and the trip places great demands on you as a participant.
The guide is responsible for the security on the trip, but you as a participant are accountable for making good preparations that ensure your readiness for such an undertaking. It is essential that you can look after yourself in demanding terrain and harsh arctic conditions. As a group you will set up/dismantle camp, engage in camp routines, boil water, cook outdoors, participate in bear watch.
