Northland reaches from Auckland up the Twin Coast to Cape Reinga's lighthouse where the Tasman and Pacific meet, with the Bay of Islands' 144 islets, the Waipoua Forest's Tāne Mahuta kauri tree, and Russell's whaling history.
New Zealand summer with Bay of Islands sailing at peak, Tall Ship Race late January, and Cape Reinga walking pleasant despite the long drive from Kaitaia.
Spring shoulder with humpback whales migrating past the Bay of Islands, pohutukawa trees blooming red in late November, and the Waipoua Forest still wet underfoot.
Autumn shoulder with sea still warm, Bay of Islands sailing pleasant, and Russell's harbour-side restaurants accessible without summer's parking pressure.
Mild Northland winter at 14°C with reliable rain, but the Bay of Islands stays accessible and Russell stays a quiet base for slow exploration.
