Unexpected cold snaps can take us all by surprise, even at the height of the summer - and some might even bring along a touch of snow with them! Be sure to include the following items in your equipment: sturdy footwear, spare clothing, canteen, protection from the wind and cold (incl. gloves and a cap), rainwear, sun gear (head covering, sun screen, sun glasses), first-aid kit for your backpack, bivy sack, sleeping bag for use at mountain huts, headlamp, maybe a telescopic hiking stick, plenty of provisions, drinks etc. A compass and altimeter will also make navigating significantly easier. Along the high-Alpine stretches of the Krimmler Törl, Granatscharte and Rauriser Sonnblick, glacier equipment (incl. crampons, ice axe, rope and harness) is essential.
Make sure you know exactly when/if they're open and providing services. Times posted at the various huts may be subject to change due to prevailing weather conditions and other circumstances, so be sure to ask ahead, especially during early and late season. Members of alpinist associations receive discounted rates at affiliated huts, and may also get priority ahead of non-members when it comes to obtaining accommodation. Sleeping bags (appropriate for use at a mountain hut) are required and are available for purchase at most huts.
The Arno Trail traces its way along previously existing Alpine- and long-distance trails that were created by alpinist associations over a period of many years. The trail is clearly signposted along its entire length within the SalzburgerLand. We owe a debt of gratitude, both to the various alpinist associations and tourist offices along the way who accepted responsibility for erecting the signs, as well as to the trail's sponsor, the Zipfer Brewery. Please be aware that use of the trail is at the hiker's own risk.
