We got married on April 13, 2013, and then 3 days later headed to South America for a 4 month honeymoon.  This trip began in Ecuador then on to Peru, Chile, Argentina and Uruguay.  One of the most fascinating stops we made was in Puno, Peru, on the shores of Lake Titicaca.

The surface of this lake sits at 12,600 feet above sea level.  We took a boat tour of a portion of the lake that allowed us to get a close up look at two remarkable indigenous cultures that live here.  One group on Isla Taquile and the other on floating islands made from reeds harvested from the lake.  Also, at the end of the article is a mention of a steamboat that operated on the lake in the mid-1800’s.

I would also mention that while in Puno we suffered through some gastrointestinal sickness, one of the only such times we encountered this type of sickness while traveling.  We had to postpose our boat tour for a couple of days until we were sufficiently recovered.
