Spent the day digging holes in the sand. Sounds great but none of my family were very impressed as I was meant to be finding a hot spring in the sand. We were at hot water beach.

I had my sandwiches in my own hole by myself, and enjoyed the warm (ish) water over my feet by myself. – full story on the Coromandel page.
