The long craggy fingers of Banks Peninsula were formed by two massive volcanic eruptions between six and 11 million years ago. The resulting overlapping volcanic cones rose to over twice the height of the present-day hills, but erosion has whittled down their summits and formed deep valleys with steep sea cliffs at the exposed headlands.
Akaroa and Lyttelton harbours formed around 7000 years ago when the sea rose and flooded the valleys. James Cook mistook the landmass for an island and named it Banks Island, after the expedition’s naturalist, Joseph Banks. The mistake was not corrected until 1809.
The Te Ara Pātaka Walkway provides excellent views over almost the entire peninsula, including its beautiful northern bays, Akaroa Harbour and Lakes Forsyth and Ellesmere, and even across the Canterbury Plains to the foothills of the Southern Alps.
The peninsula was once completely covered in native forest, but Māori began the process of clearing it and early settlers milled the timber to supply industry and building material for Christchurch and Canterbury. Most of the remaining scrub was cleared for farming, but some large patches of bush still remain.
