Hi Hitesh Kasat-
In addition to the information in this site about the destinations you have mentioned, one other piece of information is necessary for making the choices that you need to make.
That is timing. See the comments below about the timetable to help with that.
The decisions of what to see and what to skip all are very personal decisions. Everyone has different interests. Everyone has different abilities and perspectives, for example, in walking shorter or longer distances, or hiking. Your profile does not describe your interests; you have not mentioned your personal interests (other than paragliding); your message does not mention he nature of your group, if any. You do not state when you are traveling. All of that is requested of you in the link that Snowman provided. That is not for our amusement; it is so we can help you better, while also helping others , without wasting time spent messaging back and forth to understand your needs. limitations, and preferences.
So,even if we wished to guide you, we have no basis for doing so.
And, even if this is true<<"YOUR SUGGESTION WILL BE HIGHLY REQUIRED">> it is highly required that you make it, not us. We have no basis for doing so.
Once you have some idea where you want to go, and why that choice and what you mean by "quality time"( which determines how long you will spend at any place mentioned), you can figure out how long it will take to go back and forth. The Swiss Transport System offers frequent connections and comfortable travel.
and, check out the timetable, taking advantage of the valuable tips given here:
It will help you use the timetable if you use the correct spelling for the place names, as requested by Snowman, and suggested in the Forum Rules.
When I read your message title, I said to myself-
"There are dozens of mountains in Switzerland worth seeing, as well as hundreds of mountains. So, a list of mountains to skip would be many pages long, and requires criteria for choice."
Then, I read your post. This link gives a start on which ones to see by some arbitrary method of choosing:
For what it is worth...
