Gatun Locks Panama Canal, Panama

The Gatún Locks are about a mile (1.5 km) long and raise ships some 85 feet (26 m)—it takes two sets of locks to do the same thing on the Pacific side of the canal. Each of the three Gatún locks is 1,000 ft. (305 m) by 112 ft. (34 m).
There is no museum here, but there is a covered observation deck. This deck has great views not only of the locks, but also of Lake Gatún and the Caribbean entrance to the Panama Canal. Watching enormous ships pass through the locks – with seemingly no room on either side – is fascinating. ****

The locks are usually uncrowded, making it easy to take photographs and have a close-up look. There are sometimes bilingual guides on hand to explain the locks to visitors.
