As previously announced the Arlberg tunnel will be completely closed during the summer of 2017 in order to carry out essential repair work. Given that outfits are not allowed to travel over the Arlberg Pass, this would mean that campsites in West Tirol could only be reached by driving over the Fern

Pass or via Innsbruck.  However camping mediators in the Tirol and Vorarlberg have negotiated a special arrangement for caravans.  Outfits will be permitted to drive over the Pass at any time until 1 July 2017.  Between 2 July and 2 October 2017 outfits can drive over the Pass from Monday to Friday round the clock; on Saturdays, Sundays and bank holidays/feast days they will only be allowed over from 5 pm until 9 am.
