Kew Gardens is a fantastically large botanical spectacular just southwest of London accessible both by the subway or riverboat from Westminster Abbey. The park makes a fantastic day or half-day trip and is perfect for picnicking in nice weather.
The park has several enormous green houses. The largest of the green houses is the two stories high Victorian
Palm House. Built in the 1840s, it hosts a humid, tropical environment perfect for plants that would never be found native in England. Taking the old spiral metal staircase up to the top allows the visitor to walk the perimeter of the greenhouse to gain an aerial view which is quite enjoyable.
Outside the Palm House is a fantastic
rose garden on one side, which reaches its height in the spring and summer but was still impressive to me in early September, and on the other side a massive lake. The
Princess of Wales Conservatory a bit further down the lane houses a
desert environment as well as another tropical environment with a beautiful collection of
orchids and a
mangrove swamp. The other large green house is the
Temperate House. The world's largest ornamental glasshouse, it houses a collection of subtropical plants from temperate Asia, Australasia and the Pacific Islands, South Africa, and the Mediterranean.
The most enjoyable part of the park, however, is
strolling through the 300 acres of gardens, woodlands, and perfectly manicured grass. You feel ages away from hussle and bussle of the city making this one of the best places to relax/unwind (as long as the weather is tolerable). Look up more information at
