I'll be going to Peru with some friends in late July/early August for two weeks and am currently trying to build a loose itinerary. So far, that only includes Machu Picchu for sure, but we're also talking about Arequipa, Cuzco, and Lake Titicaca. I'd love to go to Iquitos, but I've read that there aren't (m)any roads, so you need to go via air or waterways. Right now airfare is $430 round trip from LIM - IQT on LAN, and from what I've found so far, it looks like LAN is the only airline that flies intra-Peru. I'd love to go by boat but am not sure how long that takes, and we're kind of limited by time and other places we'd like to see. Any help/recommendations will be greatly appreciated!
from lima the only way is by plane.
Some travelers go to pucallpa first from there take a boat,tis trip last about 3 days.
