Pass As A Local?

Maybe I can pass as a local.  It's happened in Mexico before.  My skin's tanned from cycling through the city to work over the past few weeks, and I plan to buy clothese there.  Combined with my functional Spanish, a strong Spanish "rrrr" pronunciation (especially for a Chinese guy), and a probably irrelevant salsa/bachata/merengue dancing skillset, maybe I can pull it off at times!

I haven't planned this trip as much as I wanted to.  Just scored the flight and hoped everything would fall into place like my trips before.  But eyeing through some material, I think I want to do some of these things:

- Trek to Machu Picchu, the Lares Valley trail or similar
- Explore the Sacred Valley, on bike or foot
- Explore Cuzco
- Take a breahtaking train ride from Cuzco to Puno
- See the floating reed village of Uros on Lake Titicaca, highest lake in the world
- Ride across Lake Titicaca and visit Isla de Sol on Lake Titicaca, Bolivia side
- Mountain bike down the world's most dangerous road in Bolivia
- Visit the Amazon, Madidi National Park
- Visit some UNESCO world heritage towns in Bolivia
- Ride across the great salt flats
- Check out pink flamingos on green volcanic lakes in Laguna Verde
- Chill out in San Pedro de Atacama, go sandboarding
- Visit the volcanoes in Lauca National Park
- Bike, hike, and see giant condors in Colca Canyon
- Trek around the Cordillera Blanca in the Andes
