These treks are moderately difficult, but it all depends on your hiking experience and fitness level. You need to be able to hike for full days, carrying a daypack and walking through different terrains. You’re going to be hiking five to six hours per day. You should spend time acclimatizing before your trek. That said, if you’re looking for a proper hiking adventure and you’re up to the task of full-day trekking, Peru’s Rainbow Mountain will reward you immensely!
