Northland Twin Coast Loop
Depart from Auckland to loop around Northland, seeing kauri forests, Cape Reinga, and the Bay of Islands
Follow the Twin Coast Discovery Highway up the west coast and return via the east coast. This route takes you from ancient kauri forests to the northernmost tip of New Zealand, then to the historic towns and bays of the Bay of Islands. Covering about 950 km, the pace is moderate, making it perfect for road trips and coastal scenery lovers. The trade-off is skipping diving in Tutukaka.
Coastal accommodation is tight in summer; check road conditions on SH1 Brynderwyn Hills after heavy rain.
