I visited Paris mid Oct 2002 on an official visit from USA and with the little time I had, I decided to explore the banks of the Seine from Eiffel Tower to Notredame. I took the metro train from my hotel to Eiffel Tower and started my stroll along Seine. Weather was perfect and the landmarks both old and new were impressive. No entry fee for the stroll but I took the ascensors up Eiffel Tower for around 7 euros. The shops along the riverbank near the Notredame cathedral adds a quaint character to the walk.
