I've spoken often about river cruising and how they get us into the heart of a country,
Many ocean cruises do the same. One of my fondest memories from a Greek Isle cruise I took was walking through the ancient ruins of Ephesus (picture above). Much of what remains dates as far back as 600 AD! Absolutely amazing. A more "modern" wonder, the Panama Canal, is on my must see list. I've been through small locks on rivers, but I imagine going through these big locks will be absolutely fascinating.
My transatlantic cruise last month had several stops in Iceland, and to learn their history and folklore directly from the locals was such a pleasure. It was particularly fascinating to listen to the stories about elves and trolls. They certainly seem to have a big impact on how things are done. For example, when you see the pipes that carry the heat from the geothermal centers, one can't but wonder why they zigzag versus go in a straight line. Well, the landscape has a number of rocky formations, and this is where the elves live. So instead of disturbing the elves (and consequently making them angry), the pipes go around them - thus the zigzag nature. Truth? Well, this is what is so much fun about learning local culture - the folklore is fantastic!
My goal is to inspire you to travel. These experiences are fun, aren't they? There is so much to learn from travel. No limits. Go on - Go explore!
