Kuirau park is top of the list because it is readily accessible. It is free to visit and has an unassuming charm of public gardens. The park has a well maintained playground, picnic areas and toilets creating a great space for a free trip for family and friends.
A public park has excellent signage for boiling mud pools and boardwalks over steaming pools. Enjoy the scent of sulphur infused boiling water. There is even a public thermal foot bath for afterwards.
