Brimketill lava rock pools are well... pools that are naturally created on the coastline of Iceland at Reykjanes Peninsula. Basically, all of this coastline is relatively new lava rock, in geological terms. This field formed between 1210-1240 in Reykjanes fires event. The pools are created by water erosion. The endless pounding of the waves has created several of these pools in the area.
In recent times the platform has been built there to make it easier to see these pools because its really dangerous to climb the rocks there.
Brimketill in direct translation means whitewater cauldron.
I have heard that some people even go in these pools to take a swim. I find it extremely stupid. First of all the rocks are very slippery, you can fall and smash your head. Secondly, the waves often overcome the edge of the pool and the pool drains, this can sweep you into the ocean.
After all the water in these pools is not thermally heated, it's just seawater which is around 10 degrees C so I don't find it particularly enjoyable to take a dip there anyway.
Here are some more pictures from this area.
Beautiful blue and transparent oceanic water.
For sure a special place to see!
