Yes, our partners Pilatus Bahnen, Rigi Bahnen, Treib Seelisberg Bahn and the aerial cableway at Beckenried will sell you a combined ticket or accept such a ticket issued by us.
Please note that for riding to the summit of the Pilatus you will need to exchange your paper ticket for a special pass with a magnetic stripe, once you get to their base station. This is in order to operate the barriers on site.
