Pilatus, Rigi or Titlis: which mountain suits you
You do not need all three, and none of them is cheap. Pilatus (2,132 metres) is the local mountain directly above the city: the Golden Round Trip combines the boat to Alpnachstad, the steepest cog railway in the world (48 per cent) up, the aerial cableway and gondola down to Kriens and the bus back, CHF 120 (about EUR 128) without and around CHF 70 with the Half Fare Card, a full day. The cog railway only runs from May to November. The Rigi (1,798 metres) is the "queen of the mountains", gentler, with meadows, hiking trails and a view of 13 lakes: boat to Vitznau, cog railway up, down to Arth-Goldau or by cable car to Weggis, CHF 80 to 90 without and CHF 40 to 45 with the Half Fare Card, and with the Saver Day Pass the Rigi is free because it belongs to the public transport network. That is the best deal. Titlis (3,020 metres) in Engelberg is the only one with a glacier and snow all year round; the Rotair rotating gondola costs CHF 96 return from Engelberg, plus CHF 20 for the train from Lucerne with the Half Fare Card, a full day. At the top there are a suspension bridge, a glacier cave and a lot of groups. Our honest recommendation: Rigi for hikers and savers, Pilatus for the thrill of the railway, Titlis only if you want to see snow in summer. If there is fog in the city, check the webcams first; the mountain is often above the cloud layer.
