I want to visit in Peru again!

I visited the country in 2024. It was one of the best times of my life, even though I experienced racism once. After that, I visited Chile and Argentina in November–December of last year. I found Peruvians to be the most welcoming people. I looked very different from Latinos and Europeans (who can blend in very well).

So I'm going to visit Peru and Bolivia later this year again. I'll have to skip Cusco and Picchu Picchu and I don't think I can handle less oxygen again 😂. My question is about northern Peru. Can you tell me which towns I should visit?
