There are concerns that the implementation of the Trekking Registration Certificate (TRC) means the ban of individual organised trekking in Nepal.
Although the idea of a TRC is a good one, is must not mean that you would be forced to hire guide and porters from a registered trekking agency. If one wants to trek on his own, carry his own backpack and set off, one should be able to buy this TRC from an agency and to do so!
