Tonaki tour

Dive into the deep blue

The colour of the sea in Tonaki is of a deep, velvety shade of blue.
That creates the perfect background for the local fish to stand out.
Here is a sight that will take your breath away!

While you’re in Tonaki, don’t forget to enjoy its caves and see its impressive ocean-floor drop-off point.
