How can I go on a trek with unknown people and a professional guide?

There are many trekking companies which organize numerous treks in the country. Out of which, Trekmunk is one of the best trekking companies which assures quality service. You can go directly to their website and then book the trek or else you can find the contact number and call them. Depending upon the trek, group size is decided. Generally, there are 16 trekkers in a group along with a professional trek guide. Mostly, each of them is a stranger to others. But the best part about trekking is, it binds the people together and when they return back they are no more strangers. They return back with hands on each other?s shoulders, promising to trace more peaks together in the future.
