The route starts at the Britannia Hut, which is easily approached in just over an hour from the Saas Fee cable car network. Get an early start from the hut to give you the best chance of finding frozen snow on this route, which will make life considerably easier than if conditions are poor.

Descend from the hut to the toe of the Hohlaub Glacier and cross this in the pre-dawn darkness. Follow the blunt lower section of the Hohlaubgrat ridge to where it narrows at around 3500 metres, just after a snowy dome.

Follow the crest of the ridge via some exposed (but never difficult) snow slopes to the foot of a 50 metre rock band. Climb up and diagonally right through this, clipping some metal stanchions for protection en route. The rock step is, when dry, pretty straightforward (around UIAA Grade II), but it feels a little awkward and is more time consuming when snow covered. As such, this route is best done after a day or 2 of good weather has removed any recent snowfall.

Once above the rockband, follow a short and stunning ridge onto the summit of the Allalinhorn.

Either descend the Allalinhorn's Normal Route (as drawn here) down to the Mittelallalin station or descend this line, abseiling the rock step using the metal stanchions. The majority of teams descend the normal route so as to complete an aesthetic traverse of the mountain.
