The excellent but somewhat notorious routes to the summit of Avalanche Peak attract many hikers of various abilities, and have killed 11 of them apparently. Nevertheless, both routes to the summit are marked, and the views are just fabulous, especially after a bit of snow. This was our first time in Arthur’s Pass National Park and it exceeded already high expectations, with pleasingly steep and rugged tracks up through beautiful beech forest, then epic views of mountains, ridges and valleys in all directions. The opportunity to make this a circuit walk adds to the appeal.
You should take safety preparations seriously, but experienced hikers will be fine in good conditions. (Best avoid low cloud, heavy snow, and high winds). We walked it mid-week, but there were still quite a few hikers on the mountain. I imagine this walk gets pretty busy on the weekends, but if that’s the only time you can go it will still be worth it.
