In reply to Tan92:
Hi,
As other have said for walking in general its the IML, but its a bit more complicated than that as each canton/area has some of its own rules and this can cause problems even for IML's.
For rock climbing it is a full guide. The Italians have just put it in law that they can start the process of having a recognised rock climbing instructor, but it's taken them years to get this far so don't expect anything soon.
In many countries in Europe you need by law to hold a recognised award to deliver outdoor sports (not the case in the UK), none of them allow you to just work off a UK ticket you need to officially apply and gain recognition, Pre Brexit you in Europe you could apply to have your qualifications recognised, I did it in France with my MIA, IML and kayaking awards. but now I don't think it's an option. If you have the right to work and live there after Brexit (maybe an Irish passport), there maybe a way but the ML is still a uk award so I am not sure.
over all you maybe better to do the Italian awards? I am happy to chat about my experience of setting up in France if that's any help.
cheers
