Where is the furthest place where you can see the Eiffel Tower from?

The furthest place from which the Eiffel Tower can be seen is approximately 80 kilometers (about 50 miles) away, specifically from the Montparnasse Tower observation deck in Paris, which offers a clear view of the landmark. However, in ideal conditions, the tower can be spotted from even farther locations, such as certain high vantage points in the surrounding Île-de-France region. The visibility depends on factors like terrain, weather, and atmospheric conditions.
