The northernmost way on and off Ninety Mile Beach, up near Cape Reinga, this is a popular run that follows a shallow stream between the main road and the sand. The drive winds past some towering dunes, and plenty of people pull over for a slide down them on a body board before walking to the top for the view.

Most find it a fun, gentle stream crossing. Several have done it in 2WD when the sand's firm and there's little water about, with the deepest spots only coming up to the hubs. No snorkel needed. That said, the sand goes soft and boggy in dry spells, and the stream can rise to river-like levels after heavy rain, so check the depth before you commit. Dropping tyre pressures helps if you're worried.

It's a two-way route, so watch for oncoming traffic on the corners and travel with a bit of courtesy. Keep an eye out for the wild horses that roam the area too. A must-do on the way to or from the cape.
