Climbed with rgg and my son Keith, via Allalin Glacier and west ridge - from Britannia Hut.
A point about the route: due to the condition of the Allalin glacier it is not recommended to make the lowest crossing to reach it in summer. As advised in hut we traversed the Hohlaubglacier about 100m higher up and crossed the rocky spur of the lower Houlaubgrat from Allalinhorn - and reached the Allalin Glacier about 1-2km further up. What with crossing this spur both on way up and down - and then the final pull back up to the Brittania Hut, this makes for a total of 1500m ascent for the day, as determined by rgg.
The lower crossing to the Allalin Glacier is only recommended as a ski route in winter, when crevasses and boulders covered up by snow.
Suggest check the route carefully with hut staff - we were aware of some who went astray and added a few hours to an already long day.
Long. Too long route for walking Date Climbed: Sep 19, 2006
With a group of three we walked this long long way up to the Strahlhorn. In the morning the snow was hard and held our weight. By the time we reached the upper slopes of the Allalingletscher the snow was melting and we went through the 40cm fresh snow of the past 3 days... Opening the steps till the summit we were late. The coming back was a very hard experience: all the way in the snow from the top till the Hohlaubgraat.... Only recomended with skies.
