Before booking your trip with any trekking and travel agency of Nepal, it is quite important to know whether the company legally registered within the Nepal government authorities as well as other authorized travel associations of Nepal.
It is important to be aware that there are many companies running business with expired licenses; business that do not observe the legal formalities imposed by the country act. In the same manner, we have seen many examples of so - called trekking / touring agencies illegally operated by individuals & freelancers through their own personal websites.
Additionally, we found that some tour operators overseas have been strictly involved with directly operating tours and trekking in Nepalese Himalayas without the required governmental licenses and without paying proper taxes.
Finally, if you book your trip with an unauthorized agency in Nepal or abroad, there is a greater risk that problems will occur during the course of your time in Nepal. In order to protect yourself from these trouble, take the given hints into attention prior to confirming your trip with any trekking or travel agency.
