Another easy accessible side arm is the Nigardsbreen and you can get closer to the glacier than at Boyabreen. The hike to Nigardsbreen is an out & back trail of in total around 4 km. After about one hour you will reach the glacier, so it’ll take you 2 hours to get back to the starting point. The walk has no steep ascents but the path is very uneven and slippery because there are big rocks you’ll have to cross. In the summer you can skip a part of the walk by taking a boat.
