>> 1. As per your site ... Swiss travel Pass is valid for Shilthron while at other places i found it gives 50% discount on the cable car upto the top, can you please confirm the same.
In 2018 the cable car to the Schilthorn (note spelling) is free with the Swiss Travel Pass. Up until 2017 the discount was 50%, and it will be 50% again in 2019.
>> 2. Also can you confirm if the Swiss Travel pass holder gets 25% discount for Fierst.
The Swiss Travel Pass provides 50% discount on the gondola from Grindelwald to First (note spelling).
At the link you mentioned above, you can download a map showing where the Swiss Travel Pass is valid, and what is free or discounted.
As explained in the legend on the map:
- Red lines are trains, yellow lines are buses, black lines are cable cars, white lines are boats.
- Dotted lines are discounted: discounts are mostly 50%, but only 25% for transport where you see the number "1" inside a circle near the dotted line.
- There are a few grey lines on the map as well, which indicate transport that is not covered by the Swiss Travel Pass.
- Dashed red lines on the map are railway tunnels, all of which are on routes that are free with the Swiss Travel Pass.
>> 3. Can you suggest, if I am going to Titlis, which mountain should I choose if I need to decide one mountain out of shilthron and Jungfrou.
Please note spelling: Jungfrau.
Both are memorable and very different experiences. Choosing between the two is entirely a matter of personal preference, within the constraints of time and budget. Read the information, look at the photos, and decide what's right for you.
Apart from views (none of which will disappoint), things you might wish to take into account include travel time, mode of transport (cable car, cogwheel train), cost with the Swiss Travel Pass, terrain on top (including presence of snow), activities at the top (snow play, scope to walk around outside, indoor exhibitions) etc.
