I wrote about the beach with the name "Hot Water Beach".
This picture was made around 7 in the evening.
It is low tide and when you dig a hole warm water surfaces and you can sit/lie in it and, as you can see, lots of people were digging for warm water.
We walked around a little (it was not really warm outside) and we stood with our feet in little hot water pools to stay warm (or so). I almost burned my feet.
It was fun to see old and young digging for hot water to lie in.
