The Alps 2 Ocean Cycle Trail is a cycle trail in New Zealand. This trail is one of the projects of the New Zealand Cycle Trail project. The trail extends more than 300 kilometres (190 mi) from Aoraki / Mount Cook to Oamaru on the Pacific Ocean. From west to east, it descends from an altitude of 780 metres (2,560 ft) down to sea level. The trail has both on and off-road sections.

Funding for the trail from the New Zealand Community Trust budget was approved in July 2010, after the trail had been shortlisted as one of 13 from 54 nationwide proposals.

The trail is composed of eight sections:

The first section, which is 32 kilometres (20 mi) long, starts out on a dedicated cycle trail, and continues on a gravel road. The first section is the most remote section of the trail and includes stream crossings without bridges.

Continuing on a gravel road over hilly terrain, this 43 kilometres (27 mi) section takes in the southern shore of Lake Pukaki and the hydro-electric system of the area around Twizel once on sealed roads. Towards Twizel, the cycle trail leads across the Pukaki Flats, an area of tussock grasslands that are typical for the Mackenzie basin. Twizel is the largest town along the cycle path until the conclusion at Oamaru.

The third section is 38 kilometres (24 mi) long and is the only one with a slight gain in elevation. It partly follows canals that are part of the hydro-electric system connecting the glacial lakes. A cycle trail goes around the southern shore of Lake Ōhau, finishing on a sealed road to Lake Ohau Alpine Village and the Lake Ōhau Lodge.

The next section leads through an old beech forest and includes the biggest elevation changes. It climbs about 400 metres (1,300 ft) along the Ōhau Range to the highest point of the trail at over 900 metres (3,000 ft) above sea level, before descending to about 100 metres (330 ft) lower after a total length of 40 kilometres (25 mi).

The first half of this 24 kilometres (15 mi) section over the Omarama Saddle is on a dedicated cycle trail next to SH83, from Sailors Cutting the trail follows the edge of Lake Benmore to Benmore Dam. From here it is a 6 km detour off the main route to Otematata.

Continuing into the Waitaki Valley is the sixth section. It is 44 kilometres (27 mi) long and follows sealed public roads and takes in Benmore Dam, the largest dam within the Waitaki hydro-electric power scheme, as well as Aviemore Dam and Waitaki Dam. An off-road 16-kilometre bicycling section was opened on 17 December 2020, from Sailors Cutting to the top of the Benmore Dam in the Waitaki Lakes region. $1.2 million was spent creating the section.

From Kurow, the cycle trail continues 23 kilometres (14 mi) off-road to Duntroon. The area contains limestone formations, Maori rock drawings and dinosaur fossils.

The last section partly follows the Vanished World trail and past the Elephant Rocks on a mix of sealed public back roads and dedicated cycle trails. From Weston, the cycle trail follows an old railway line and enters Oamaru via the Oamaru Gardens. It finishes after 55 kilometres (34 mi) at Friendly Bay, adjacent to Oamaru's Victorian Historic Precinct.
