About Kai Iwi Beach
The cliffs and rock formations at Kai Iwi are what set it apart from Whanganui’s other beaches. Eroding clay bluffs back the beach for much of its length, and at low tide the exposed rocks and driftwood shapes make it genuinely photogenic — particularly in the late afternoon light. The beach faces directly west onto the Tasman Sea and picks up consistent swell throughout the year.
The playground has become a local landmark of its own — a flying fox over the stream, a pirate climbing ship and wood-fired BBQs make it a complete family stop. The Kai Iwi Beach Holiday Park is on site for those wanting to stay overnight.
