Warming temperatures have caused large stones to break off the cliff at Reynisfjara beach, South Iceland. A post in a closed Facebook group for tourist industry workers warns guides about conditions at the popular site.
Reynisfjara black sand beach is one of the most-visited tourist destinations in South Iceland, featuring impressive basalt stacks and panoramic views.
As warm temperatures follow a period of frost in South Iceland, there is increased danger of rockfall. Others in the group warn guides and travellers against lingering under cliffs and rock formations in the coming weeks.
