Many of our senior career women readers are too familiar with glass ceilings. Now, travels can take them to sky-high places where they’ll enjoy glass floors and breathtaking views.

The venerable Eiffel Tower, celebrating its 125th anniversary, now offers visitors a high floor with a clear glass bottom that reveals the city of Paris 200 feet below.
