Fjallsárlón is a glacier lake at the south end of the Icelandic glacier Vatnajökull. The famous volcano Örćfajökull volcano, the largest active volcano in Iceland, looms above (although not sure I got it in my photos as it was pretty hard to see anything due to the deteriorating weather!). We stopped here on our way back to Reykjavik with better light.
