We took train from Luzern to Engelberg ( a small town down the Mt.Titlis). From Engelberg, we took bus, gondola, cable car and last Rotair(The Titlis Rotair - the world's first revolving cable car) to reach the summit of 10,000ft. Approx. total journey from Luzern train station to Mt.Titlis was about 2hours. So advised to go early in the morning and check weather condition before go.
