About Castlecliff Beach
Castlecliff is a long, flat west coast beach backed by low dunes. The prevailing swell comes straight off the Tasman Sea, which makes it good for surfing — particularly near the south end beside the Whanganui River mouth — but requires respect in the water. The beach has numerous rips and an uneven bottom. When the Surf Life Saving Club is patrolling, swimming between the flags is the safest option.
The top car park on Rangiora Street provides one of the better sunset viewing spots in the Whanganui area, with unobstructed views west over the Tasman. The motor camp and skate park alongside make it a practical base for a longer beach day.
What Visitors Say
“Beautiful wild beach — huge open sky, surf crashing in and almost nobody else there on a weekday. One of those places that feels properly remote even though the city is just 10 minutes away.” — Lonely Planet, Castlecliff Beach listing
