What should I do if I fall off the mountain and get hurt while traveling with a travel agency?

There are many factors to deal with this kind of request.

First, even on the way up and down the mountain, there are cases such as ordering "tourist restricted areas" and "tourists drinking". If you fall in this kind of place, it is irresponsible for the insurance company. This is the responsibility of tourists

Second, if a travel agency leads tourists to climb a mountain in a "non-tourist area", it will be responsible for the "Travel Agency Liability Insurance".

so telling us what happened will help us to help you solve it.
