Zoom your map way out and Panama looks like a small sliver of land, so a trip through its famous canal is a quickie, right? But not so fast — traversing the Panama Canal actually takes at least 20 hours! Cruise it and enjoy a zoomed-in real-life look at perhaps last century’s greatest engineering achievement… along with its surrounding lush, verdant lands. This testament to human audacity joins the Pacific and Caribbean in the most direct way possible, and is worth making a leisurely part of your vacation.
