When I was looking the websites of the attractions of London, one of the places that most called my attention was the Kew Gardens. It seems a beautiful park, with lots of places to visit (buildings, lakes, a walk through the treetops, etc. ) and a big garden to travel in.
Another reason is that the entrance fee is not so expensive, compared with the other fees. I also really like the trees and green places, so, to me being in a giant garden would be really good, funny, entertaining, interesting and relaxing.
And this is the end, my only friend, the end.
