Whariwharangi Beach, Abel Tasman National Park.
Just back after five days in Golden Bay, staying with a friend in Wainui at the northern end of the Abel Tasman. We did the top of the Abel Tasman walk on Friday afternoon: from Totaranui to Wainui via Separation Point (300k map here). The beach pictured is right at the top of the park. Weather perfect.
We saw only one stingray at Wainui. As we were having the last swim of the day in the warm water of the incoming tide, one swam to have a look at us. We left the water rather promptly.
