A nice day trip is a visit in Richmond and on the way back Kew Gardens.
Richmond sits on the south side of the river Thames. If you have a 7-Day Travelcard for zones 1 and 2 (and I remommend to buy one if you stay that long) the return ticket only costs about 3 pounds. Famous is the Richmond bridge which was built in the 18th century. 1937 they widened the bridge due to increasing traffic.
In Kew Gardens you have to walk he Rhizotron & Xstrata Treetop Walkway. This walkway gives you the opportunity to walk high above the ground through the tree canopy of sweet chestnuts, limes and deciduous oaks. If you are lucky you see birds, insects, lichens and fungi that rely on these huge organisms. The walkway is about 200 meters long and is really thrilling.
You also have a great view of the vast 300 acres of Kew, as well as the London skyline. It is designed by Marks Barfield Architects, the architects of the London Eye. The pioneering structure of the Xstrata Treetop Walkway is an ingenious design based on a Fibonacci numerical sequence, often found in nature’s growth patterns. And if you have forgotten what the Fibonacci numbers are, here the reminder 🙂 : 0,1,2,3,5,8,13,21,34,55,…
The central part of the Temperate House was designed by Decimus Burton and finished in 1861. It was very expensive and because of financial constraints the construction of the two side-parts was delayed until 1899. It is the largest glasshouse at Kew and the world’s largest surviving Victorian glass structure. It contains plants from Asia, Australia, Pacific Islands and Africa. You can even walk up and view the trees and plants from above.
