Isthmus Peak is the connoisseur’s alternative to Roys Peak. The ridge rises between the two great lakes of the district, and from its summit you look west over Lake Wānaka and east over Lake Hāwea, with the Southern Alps ranged beyond both. The track climbs through open tussock country from a roadside car park on the Lake Hāwea side, a steady climb of roughly sixteen kilometres return that usually takes five to six hours. There are no technical sections, but the ascent is long and the terrain exposed, with no shade, shelter or water on the way. The views are exceptional, the crowds are thin, and on a clear day you can follow the glacial valleys down toward the Hunter and Matukituki. It is a walk for those who like a proper day in the hills.
How to visit
The trailhead is on the Wānaka–Hāwea road close to the saddle between the lakes, about fifteen minutes by car from Wānaka town and a similar distance from Hāwea township. There is a small car park, and no public transport, so you will need a vehicle or a shared ride.
The track crosses farmland and is closed during the spring lambing period, typically from early October to early November, so check the Department of Conservation page before you go. Allow a full day, and start early to avoid the afternoon heat and give yourself margin for a slow descent.
What to expect
The track begins with a steady incline across paddocks and then switches back up the side of the ridge, climbing about 1,100 metres in total. The path is well formed, marked with poles in places, and easy to follow in clear weather. Higher up, the tussock opens out and you reach the broad summit ridge, where the wind can be fierce and the temperature considerably lower than in town.
Carry at least two litres of water, sun protection, a warm layer, a windproof jacket and snacks. Dogs are not allowed, and there is no cell coverage on parts of the route, so tell someone where you are going.
Making the most of it
The best days are clear and calm, when the two lakes sit in different shades of blue and the mountains show sharp detail. Autumn offers cooler temperatures and golden tussock, while winter and early spring may leave snow on the upper slopes, which requires experience and suitable gear.
The walk is less photographed than Roys Peak, so you can often enjoy the summit alone. Reward yourself afterward with a swim at Lake Hāwea or dinner in Wānaka. If conditions are poor, choose a lower walk such as Mount Iron or the lakefront paths and save the ridge for another day.
Good to know
Because the route is so exposed, thunderstorms and sudden weather changes are a real risk, so check the mountain forecast and turn back if cloud closes in. Start with full water bottles, since streams on the lower slopes are not reliable and stock graze the land. Sturdy footwear matters on the descent, where loose gravel and tired legs combine, and walking poles can save your knees. There are no toilets on the track, so use the facilities in town or at Hāwea before you set out, and carry out all rubbish.

They are similar in length and effort. Isthmus Peak is often quieter, with views of both lakes, while Roys Peak has the famous mid-way lookout.
When is Isthmus Peak closed?+
It closes for lambing in spring, usually early October to early November. Snow and ice can also make it unsafe in winter.
Where does the track start?+
It starts from a small car park on the road between Wānaka and Hāwea, about fifteen minutes from either.
Can I take my dog?+
No. Dogs are not permitted because the track crosses working farmland.
