Which of NZ's Great Walks should you actually book first?
Book Milford, Routeburn or Kepler the day bookings open in May if you want a December–February date — those three routinely fill within an hour, some within minutes. Everything else on the list — Waikaremoana, Tongariro Northern Circuit, the Whanganui Journey, Paparoa, Rakiura and Hump Ridge — you can usually still book in the same season with a few weeks' notice. There are 11 official Great Walks as of 2026 (Hump Ridge Track became the 11th in October 2024), and DOC opens the next season's hut and campsite bookings in a single staggered window each May, with each track releasing at a set time (9:30am or 12pm NZST).
A note on dates: the 2026/27 season's bookings opened 12 May 2026 for stays through 30 June 2027 — but DOC resets its exact opening date and window length every year, so treat any specific date here as indicative, not a fixed annual fixture. Always check doc.govt.nz for the current season before you plan around it. Milford's sell-out speed also varies year to year — sources range from as little as 12 minutes to about 40 minutes after release — so "sells out fast" is the reliable takeaway, not any single number.
- Milford Track (Fiordland) — 4 days, 53.5 km, one-way. Formed, but committing: no exit until Milford Sound. Books out fastest of all 11 — some seasons within 12–40 minutes of release. Wrong choice if you can't commit to a fixed booking date months out.
- Routeburn Track (Fiordland/Mt Aspiring) — 2–4 days, 32 km, the shortest Great Walk. Alpine crossing at Harris Saddle means it closes to the general public outside the guided/independent season (roughly late Oct–late Apr). Sells out nearly as fast as Milford for peak weekends.
- Kepler Track (Te Anau) — 3–4 days, 60 km, loop. Exposed alpine tops around Mt Luxmore get closed in bad weather even mid-summer — check the forecast, not just the calendar date.
- Abel Tasman Coast Track (Nelson) — 3–5 days, 60 km, one-way. The easiest-graded of the 11 and the one people day-walk in sections via water taxi rather than commit to the whole thing.
- Heaphy Track (Kahurangi) — 2–6 days, 78.4 km, walk in and out from either end. Longest Great Walk; open to mountain bikes 1 May–30 Nov, which changes the walking experience in shoulder season.
- Paparoa Track (West Coast) — 2–3 days, 55 km, one-way. Newest of the 11 (opened 2019) and still the quietest of the mainland Great Walks.
- Tongariro Northern Circuit (central North Island) — 3–4 days, 43 km, loop. Day two follows the Tongariro Alpine Crossing over active volcanic terrain — check DOC's alert page before you go.
- Lake Waikaremoana Track (Te Urewera) — 3–4 days, 46 km, one-way, both ends reached by water taxi. Less contested than the South Island walks; a reasonable first Great Walk.
- Whanganui Journey (Whanganui National Park) — 3–5 days, 87 or 145 km — a canoe trip on the river, not a walk on foot, despite being managed under the Great Walks system.
- Rakiura Track (Stewart Island) — 3 days, 32 km, loop. Reached by a 20-minute flight from Invercargill or a 1-hour ferry from Bluff, which adds real cost and weather-dependence before you've taken a step.
- Hump Ridge Track (Southern Fiordland) — 3 days, 60 km, loop. Booked separately through the Hump Ridge Trust's own website, not DOC's system, and can be booked up to two years ahead.
