After opening another thread about planning our trip, we are flying into Lima and going straight to Arequipa for a couple of days. We were then looking at going to Colca Canyon, back to Arequipa and then the bus to Puno for Lake Titicaca, then eventually on to Cusco for a couple of nights and do the Inca Trail. This route seemed to be more popular than flying into Cusco and doing it the other way round.
My question is that if you had a choice would you go to Colca Canyon or climb El Misti. We've been to the Grand Canyon and Kings Canyon and I just wondered if we are really missing something by not going to Colca Canyon and choosing El Misti instead. We don't have enough time to do both as we only have 17 nights in total and trying to plan something around the Inca Trail, Cusco and Lake Titicaca.
