“Authentic Island experience”
I loved Enoshima. Enoshima is easily to reach from Tokyo and perfect for a beach day. The beach is really close to the station and a long bridge leads you to the actual Island. It is small, so you can walk the path all over the Island in less then an hour. At the back side there is also a small beach with many rocks where you can take many pictures. Though crowded, the atmosphere on the Island was really nice, with many shops selling delicious fresh seafood and yummy snacks. One tip, if you go in the evening you will find less people, but careful to not miss your train back!
