Panama Canal cruises combine this world-famous waterway with great ports in the Caribbean and/or Mexican Riviera. Cruise the Panama Canal and see the massive engineering marvel that was built to connect the Atlantic and Pacific oceans. Construction on the canal began in 1904 and was completed 10 years and $387 million later. On cruises to the Panama Canal, six immense locks raise the cruise ship from sea level up to 85 feet, then gently lower it --sometimes with only inches to spare on either side. On your Panama Canal cruise, join other passengers on the decks as a canal historian explains the workings of the locks and points out sights along the way.
