Eraldsbreen is a glacier arm of Jostedalsbreen, it is nicely situated by the cold glacial lake.
Take off from RV15 towards Erdalen in Oppstryn. Park at the bottom of the last farms, or you can drive a little further on the toll road. From where you park, there is a good path all the way to Vetledalssetra, here it is nice to take a break before continuing on the path to the glacier. By the glacier you will also find an emergency shelter that is possible to spend the night in.
