Alps 2 Ocean Cycle Trail

The route

The trail is signposted in nine sections, eight of them in sequence and one an alternative start from Lake Tekapo. It is meant to be ridden west to east, and almost everyone does.

From White Horse Hill campground an off-road track runs about eight kilometres down the Tasman valley to Mt Cook Airport. The helicopter sets you down on the far side — the landing is Rotten Tommy on one official page and Tasman Point on another, and we take them to be the same place — and a rough track with creek crossings brings you to the Jollie car park at the top of Hayman Road, then gravel road to Braemar Road — 35km for the section. The second section follows Hayman Road down the eastern shore of Lake Pūkaki past the Tekapo B power station, picks up an off-road trail along the shoreline, crosses the Pūkaki dam to the visitor centre and runs across the Pūkaki Flats to Twizel, another 40km. The Tekapo alternative leaves Takapō township on the canal road and joins this section at Hayman Road, 55km to Twizel.

From Twizel, Glen Lyon Road and the canal road lead to the edge of Lake Ōhau, an off-road trail crosses the Ōhau weir and skirts the foreshore, and the sealed lake road finishes at Lake Ōhau Lodge, 38km. Then the climb: six easy kilometres to Freehold Creek at 600m, a steady ascent through beech forest to the high point at 900m, a rolling and in places steep descent to the derelict Quailburn woolshed, and gravel road down to the Ahuriri campsite and Ōmarama, 43km. The trail's two official sources give this section as 43km and 45km; we use the trail's own figure.

East of Ōmarama the country changes. Over the Chain Hills the trail meets Lake Benmore and follows it to Sailors Cutting and the Benmore dam, then a spur into Otematata, 35km. From Otematata it climbs back onto the dam, runs the northern shore of Lake Aviemore on Te Akatarawa Road, crosses the Aviemore dam, passes the ghost town of Wharekuri and the Waitaki dam, and comes off-road into Kurow, 44km. Kurow to Duntroon is 27km of river flats, three braided side-rivers and a vineyard, with the Takiroa Māori rock art site across the highway near the end. The last day, 54km, goes through Elephant Rocks and Island Cliff, through the Rakis railway tunnel, along the old branch line through Windsor, Enfield and Weston, down through Ōamaru's public gardens and the Victorian precinct to the harbour.

Direction matters here more than on most rail trails. West to east is generally downhill, and the prevailing wind should be at your back. The trail's FAQ notes that e-bikes are bringing more riders the other way and that on the canal and lakeside sections the gradient hardly matters — but the wind is still the wind.

What the riding is like

Two days of open high country under mountains, one day of climbing, three days of lakes and limestone. The trail's own materials are unusually frank that it is not flat, and unusually proud that it is not boring.

The Mackenzie Basin is tussock, gravel and light. The lakes — Pūkaki, Tekapo, Ōhau — are fed by glacier rivers carrying ground-up rock so fine it stays suspended, and the colour that produces is the one people photograph and do not believe afterwards. There are no trees to speak of on the first two days; there is Aoraki, 3,754 metres, in view for most of a day's riding.

The climb from Lake Ōhau Lodge is the one section that asks something of you. It gains three hundred metres between Freehold Creek and the high point, and the trail's own page warns of false summits — places where the track seems to level and then keeps winding up. The safety notes say to do it in the cooler part of a summer day, carry two litres of water, and treat the top as alpine whatever the forecast said in Twizel. The descent is called moderately technical, and less confident riders walk the first kilometre.

The Waitaki valley is a different kind of country: warmer, greener, engineered. Three dams in two days — Benmore, the largest earth dam in the country, then Aviemore, then Waitaki, built largely by pick and shovel — and between them long lake shores, the ruins of Wharekuri's hotel, the country's smallest wine region, and rock shelters where Māori drew on the limestone. By Duntroon the hills have become escarpments, and the escarpments are white.

The stages

The trail publishes three itineraries — four, six and eight days — and calls the six-day one the Classic. It is the one below, with the eight-day version simply one section a day.

The distances are the trail's own section figures, added together; day four is two sections and the longest day, day five one short one. The trust's second six-day option moves the long day earlier — Ōmarama to Otematata and Otematata to Kurow become days three and four with the climb on its own — and that is the version to choose if seventy-nine kilometres after the climb sounds like too much.

Eight days is one section a day, and it is the itinerary the trail calls Relaxed for a reason: a leisurely pace, sight-seeing on the way, and a spare day if you take the Tekapo start. Four days is two sections a day and three on the third, which the trail says is for fit and experienced riders or e-bikes, and we would add that it leaves no time for the things this trail is actually for.

The overnight stops are towns, with one exception: Braemar Road is a road junction rather than a place, which is why the six-day itinerary rides straight through it. If you want to break section one there, ask an operator what the options are before you count on one.

Bikes, bags and booking

The trail is free. Almost everything around it is a booking, and the helicopter is the one that decides the shape of your first day.

The Tasman River crossing. Two operators fly it from Mt Cook Airport, both on demand and both weather-dependent. Southern Lakes Helicopters lists its bike transfer at from NZ$232 a person — a figure we read at its online checkout on 5 September 2026, not from a brochure, and will read again. Mt Cook Ski Planes & Helicopters quotes NZ$960 for a private group of up to six on its website, with scenic landings as add-ons; when we looked, its online calendar showed no September availability and asked callers to phone, so treat that figure as the website's and confirm it. Neither is linked here, because the trail's own page for one of them currently points at a dead address — go through the A2O helicopter page below. Minimum two people; if the river is in flood the landing moves to the Jollie car park at extra cost.

Getting to the ends. Christchurch, Dunedin and Queenstown airports are each two to four hours' drive from the trail, and InterCity buses serve Tekapo, Aoraki/Mt Cook Village, Twizel, Ōmarama and Ōamaru. The trail names Twizel and Ōamaru as its main hubs. Book everything ahead for December to April, and expect some smaller places to close in winter.

What to ride and what to bring. A mountain bike is best; a hybrid or tourer with treaded tyres will manage, and the FAQ notes the trail has been done on a penny-farthing. E-bikes are permitted up to 300 watts. Take a torch for the Rakis tunnel, high-visibility clothing for the road sections, warm and waterproof layers all year, and a personal locator beacon, which can be hired along the trail. A helmet is compulsory everywhere in New Zealand. Dogs are not allowed on the trail, and it may be used only in daylight.

If something goes wrong

The trail runs through alpine weather at one end and working farmland and hydro schemes at the rest of it, and its conditions page is updated often enough to be worth reading on the morning you set off.

Wind. Every exposed section carries the same warning: be careful on bridges, consider dismounting. On the Tekapo canal road there is a signed stretch six kilometres south of the highway crossing where riders are told to take the lower road in high wind, and the page says failure to do so may result in severe injury. On the narrow Grade 3 shore of Lake Benmore there are drop-offs and the advice is the same.

Water. The Ōhau weir closes when the lake spills over it, and the fix is a shuttle from Twizel to Lake Ōhau Lodge. The three rivers between Kurow and Duntroon are dry in summer and dangerous in flood; when they are up, the route is the highway, and each river has a signed exit track. As we write, the Three Rivers section is closed for high flows until further notice, which is exactly the kind of thing to check.

Dams and roads. The tops of the Benmore and Aviemore dams close for maintenance on advertised days, with a signed highway alternative from Otematata. Logging trucks use Braemar and Hayman roads on the first two sections, four movements a day on a programme running for years: keep left, single file, high-vis. The climb from Lake Ōhau crosses an avalanche path, and the advice in winter is not to linger on it.

Getting help. Coverage is patchy on the Lake Ōhau climb and along Lake Benmore, and the trail recommends a beacon for both. In an emergency call 111 and say you are on the Alps 2 Ocean, which triggers the trail's own plan with St John. Magpies nest from July to December; the trail asks you to pass through calmly.

Shorter versions, and longer ones

Because it is signposted in sections with road access at every junction, this is an easy trail to ride in pieces — and the trail publishes its own day rides.

The classic single day is Lake Tekapo to Twizel, 55km on the canal road with the Tekapo B lookout over Pūkaki halfway, and no helicopter. Twizel to Lake Ōhau is 38km and a swim at Loch Cameron; the trail suggests riding it either way and letting the lodge bar decide your shuttle time. Lake Ōhau to Ōmarama with a shuttle drop is the climb and the view without the rest, and a detour to the Clay Cliffs. Aoraki/Mt Cook to Twizel in a day, about 75km with the flight, is possible for a strong rider with an early drop-off.

A weekend is any two adjacent sections with a night in Twizel, Ōmarama, Otematata or Kurow. Ocean to alps, the whole thing backwards, is increasingly ridden on e-bikes and gives you the mountains growing rather than shrinking, at the cost of the wind.

And the longer version is the next Great Ride south. The Otago Central Rail Trail runs 152km from Clyde to Middlemarch, is flatter than anything here, and its Middlemarch end is a morning's drive south of Ōamaru. Riders with a fortnight do both; we have a page on it, and the two make a natural pair — one for the mountains, one for the silence after them.
