A favourite since pre-European times, Miranda Hot Springs are just off State Highway 2, only 45 minutes drive from Auckland.

There are also four private spa pools. Great fish'n'chips at Kaiaua are a mere skip up the road, and the nearby Miranda Holiday Park has a reputation for spotless cabins and its own landscaped pool.
