Mt Pilatus is definitely a classic in Switzerland and worth a visit in every season. In Summer its an area full of wonderful hikes and winter is a snowy paradise.
How to get there: There are three different ways of going up. Option 1 is taking the train from Alpnachstad up to Pilatus Kulm. Option 2 is from Kriens up to Pilatus Kulm. Option 3 is hiking up. The Hike up from Alpnachstad to Pilatus is 5 hours and 7.5km long and pretty tough. The way back down is the same one. You can also only hike up and take the train down or vice versa.
Price: Option 1 and 2 are 72chf return without a reduction or 36chf with the half fare/swiss travel pass.
