There are two little islands in the middle of the River Seine Île Saint Louis and Île De La Cité both amazing islands to visit with Île De La Cité probably the most famous ,certainly the most visited .
Île De La Cité ( City Island ) is such a great place to visit ,my twin brother Stephen and I had just enjoyed beers in Le Mistral and we then decided to walk over Pont Au Change onto the Île De La Cité,love it here ,the architecture is amazing ,the Conciergerie,Palais De Justice De Paris,Tour De L'Horloge Du Palais De La Cité, Profecture De Police ,Sainte Chappelle and of course Cathedrale Notre Dame De Paris,a landmark building on the island .
We wandered around this island in the centre of the River Seine , dropped into a couple of cafe bars to enjoy some beers ,all in all it's a great area of the city to enjoy of you're planning a holiday go Paris.
