Lonely Planet’s guide to the South Island’s best secrets

Saturday, 4 July 2026

Lonely Planet's latest guidebook ‘Secret Wonders of the World’ shines a spotlight on five extraordinary South Island locations where dramatic landscapes reward those willing to venture further. The following extract has been republished with permission.

Sparsely populated and buffeted by westerly winds, New Zealand’s South Island (Te Waipounamu) is much wilder than its neighbour to the north. The Southern Alps run down the South Island like a spine, and the West Coast is a mood board of nature’s ferocity: wave-smashed cliffs, rivers powered by glacial melt, and rainforests threaded by tannin-stained streams.

Glorious wilderness isn’t the only drawcard. The South Island is also brimming with novel sights, like Whataroa’s one-of-a-kind heron breeding site, and an ends-of-the-Earth landmark with gale-flattened trees.

Many visitors come purely for solitude, to seek respite on odyssey-length hikes or cruise into the ‘Place of Silence’ – but living here full-time demands resilience. Spend time on the South Island and you’ll soon soak up the locals’ dry humour and can-do spirit.

Tunnel Beach, near Dunedin

The South Island is rich in soul-stirring coves, but one in particular feels like a portal to an unearthly realm: Tunnel Beach. Its passageway was carved into the sandstone in the 1870s, and spiny remnants of fossilised sea creatures are still visible in the rock.

As you emerge on the other side, you face the angry ocean from a beach of dove-grey sand. Let the roar-ing waves quiet your mind.

Slope Point, near Curio Bay

Land’s end on the South Island is a bright yellow sign declaring the distances to the equator and South Pole (5140km and 4803km respectively). It’s only a short walk from the trailhead, but Antarctic winds are against you the entire way – expect your hood to inflate like a parachute. Note the thatch of trees by the trail, so blasted by the unobstructed wind that they grip the earth at a 45-degree angle.

Doubtful Sound, Fiordland

The epic fjords and peaks of Milford Sound draw more than a million annual visitors, leaving nearby Doubtful Sound to live up to its Māori name: Patea, the ‘Place of Silence’. Cruise boats ply the midnight-dark waters, and there are no human settlements for hundreds of miles in any direction – just the hiss of waterfalls and the occasional splash of fur seals flopping into the fjord.

Kōtuku Breeding Ground, Whataroa

Māori traditions say it’s lucky to see a kōtuku (white heron); in Whataroa, then, you’ll be showered by good fortune. This is the world’s only known nesting site for these rare, lace-winged birds. White Heron Sanctuary Tours takes you into the reserve to watch these pearl-white birds swoop down from 1000-year-old trees to preen like dancers in the marsh.

Pancake Rocks, Punakaiki

Even the rocks seem alive at Paparoa National Park, where icy waves foam up through blowholes, and limestone crags look like human silhouettes. The most intriguing landform is at Punakaiki, where 30 million years of geological pressure have created spindles of limestone that look curiously like stacks of pancakes, thanks to imperfections in the rock.
