Lake Tikitapu

Lake Tikitapu

In ancient times, the daughter of a high born chief was bathing in its crystal waters and wore the Tikitapu (sacred greenstone neck ornament). The piece dislodged itself while she swam and the blue waters of the lake are believed to still be hiding the tikitapu.

Lake Tikitapu is a small, circular lake framed by pretty native bush and forestry. Famous for its striking colour, it is commonly known as the Blue Lake and is adjacent to the slategreen coloured "Green Lake" / Lake Rotokakahi. With a water slide and an easy walking track around the lake, it is a popular location for family outings.
