Crucible Lake Track

Crucible Lake Track is the out-and-back side trip from Siberia Hut to an alpine lake high beneath Mount Alba. The hut-to-lake leg is listed as 7 km and 3–4 hours; allow about 14 km (8.7 miles) and 6–8 hours round trip, before long stops. This is a serious backcountry day, not a quick lakeside walk. It is worth the effort for a route that changes from broad valley flats to forest, a snow-grass basin and, at the end, a rock-framed lake. If you are starting in Makarora, reaching Siberia Hut is a separate, much longer journey; do not count this distance from the road.

From Siberia Hut, follow the open valley for about 2 km and cross Gillespie and Siberia Streams to their true right. The first stretch looks gentler than the climb ahead, but the streams can set the whole day’s plan: after rain, Gillespie, Siberia and Crucible Streams can become impassable. Check water conditions before leaving the hut, carry time for a wait, and turn back if a crossing is not safe. The route enters forest on the true left of Crucible Stream, climbs a narrow spur, then sidles across the slope to the next crossing. This is where the valley floor gives way to a sustained climb.

After crossing Crucible Stream, the track emerges onto a snow-grass flat on the true right. Follow the poles up the upper basin, then climb the rock moraine to the lake. The open ground and the final rocky slope take longer than they look from below. Snow grass is slippery when wet, and the loose stone needs careful footing on both the climb and descent. Keep the markers in sight, stay on the established line through the fragile alpine vegetation, and carry a map or navigation device for this remote route.

The lake sits high above Siberia Valley under Mount Alba. Turquoise water, dark rock walls and snow make the outlet the payoff for the long approach; floating ice may be present, but it is never guaranteed. Look among the large rocks at the outlet for pīwauwau, or rock wren, a small native bird often seen there. Give yourself time to enjoy the basin, then remember that the return retraces every stream crossing and the moraine descent.
