Originally discovered by Captain James Cook in 1769 and today cited as one of the top beaches in the world (surfers love it,) Hot Water Beach on the Coromandel Peninsula of New Zealand’s North Island is geo-thermally busy. For two hours before and after low tide, you can create your own personal spa pool by digging in the sand for hot spring water. As the tide comes in, cooler waves trickle over the hot pools, and there you have it … and dug by you.
