In a word, no. All of the hiking on our IMC trip will be day-hikes that are accessible from the each campground where we'll stay. We will stay at front-country campsites each night and have continuous access to running water every day of the trip. Our time in Skaftafell is the only part of the trip where we will need to pack 3 days worth of food as we will be in the National Park where there is not access to a grocery store.
