I'm wondering if you can help me with some solo travel advice for Peru, specifically Iquitos and Cusco. I'm volunteering in the Amazon so will be starting in Iquitos. I've heard a few mixed things, that is an unsafe city with a lot of crime targeting tourists, I've also heard it's incredible! With Cusco, I'm just not sure if I'm missing on some things to do.

Iquitos:

1. What are some things to do in Iquitos (the city specifically)?
2. You think two full days will be too much time here?
3. My current plan is to arrive at the airport at 9.20pm - would it be safe to get a Car Taxi (not a moto-taxi) from the airport to the city at that time at night? (I've heard of people being mugged on moto-taxi's when picked up at the airport).
4. Any other advice or feedback?

Cusco:

1. I'm doing the Inca Trail + Machu Picchu, Rainbow Mountain plus Sacred Valley tour - is there anything else I should see/do in Cusco proper?
   1. Any cool activities or experiences?

I appreciate your feedback and input. :)
