During the summer of 2011, we began planning for our trip to Peru. The Adventure Life travel agency of Missoula, Montana, specializing in Central and South American travels, was selected as we endorsed their philosophy of utilizing local lodging, transportation and guides, maintaining small groups, and being ecologically responsible. Our tour guide for the first 10 days from Lima to Puno was Carlos Lazo, while our guide for the last 5 days in the Cusco region was Teddy Romero. A mother and her 17-year-old son (Sarah and Christopher) were the 2 other members of our group. Peru is in the Eastern Time Zone but does not observe daylight saving time. Sunrise occurred at approximately 6:20 am and sunset near 5:50 pm. Peru is located in a temperate zone and has two climates – wet (Dec – Mar) and dry. Days were sunny with temperatures between 60-70 degrees. Nights at higher elevations dropped between 30 and 40 degrees.
