Is hiking in Morroco safe? How about for solo female travellers?

In general Morocco is considered safe for visitors, though you don't have to research very far to come across the brutal murder of two Scandinavian tourists by self-identified Islamic State supporters in December of 2018. Forbes ranked the county #8 least-safe for women shortly after, primarily on the basis of gender inequality and street safety. The latter especially seems to be a common source of problems for female travellers: catcalls, street harassment, and unwelcome attention.
