Best known for connecting east to west, the Panama Canal is the right thing in the right place for speeding up transit by sea. But what about taking it slow? It’s great for that too! With its mouth located on the Atlantic near the city of Colón, this decades-in-the-making canal flows past the lush green scenery surrounding the canal's impressive Gatún Locks, on its way towards the expanse of Lake Gatún itself. You’ll go with the flow as you enter — and exit — the lake through these locks, getting two chances to take in up-close views of the land.
