This route connects the Boulder Lake Track (about 20km) with the Anatoki Forks Track (also about 20km). Between them is 15 km of scrambling along and below a high ridge. The views are magnificent but the going is very slow, with significant amounts of rock scrambling. Contingency planning is essential in case of problems with injury, weather, etc. The ambitious and well-prepared runner is rewarded with incredible views.

Boulder Lake Track and Anatoki Forks tracks are both maintained but fairly rough in places with multiple stream crossings, fallen trees, slips, etc. The route from Boulder Lake to Yuletide Peak is not maintained and is marked only by cairns -- it is very slow going and some way-finding is required.

This trail includes the peak Yuletide Peak.

Dam workings can be found at Boulder Lake, but requires a detour. The Kahurangi Ranges and the view to the Dragons Teeth in particular are magnificent.

If you know of any public toilets near the trail start or on the route, please login and then let us know so we can update this section.

Plenty of parks normally available. You could probably get a bus to Bainham and walk 4-5km from there.

Following the two tracks is relatively straightforward. It is essential to have a map that you have studied for the middle section, as in various places you will likely find yourself off the path and you'll need to know where you trying to go in order to find it again.

Only possible to do in one day in dry weather. Pay close attention to the weather forecast. If bad weather is moving in, turn around and exit back via the Boulder Lake Track as the ridge is very exposed.

Heights, rocks, potentially exposed to bad weather. There are huts at Boulder Lake and Anatoki Forks, as well as Adelaide Tarn (slightly off route) so bring enough gear that you could shelter overnight if necessary.

Ran/hiked this in reverse. Track now easy enough to follow in most places. What a stunning route. Despite numerous trips along the HDT this was my first time on to Yuletide- such great views onto the Dragons and Anatoki & a very different perspective. Beware there might be no drinkable water between Anatoki Forks and Green Saddle. Anyone wants help with logistics don't hesitate to email me at

This was the very first South Osland backcountry I ever laced up for. First time round ot was a Dragons Teeth through Tramp to Cobb. A decade later came back and travelled the route described. Anatoki Forks Hut had a wetback shower which was great as heavy rain made us sut out a night at the hut- tributary creeks that cross the trail downstream of the hut were totally uncrossable washing machines! There is some careful routefinding to nail after Boulder Lake and Yuletide. Pack as if prepared for anything! Totally 5 stars, great countryside
