Lovely walks, huge plant houses, intriguing plants. Kew was one of my favorite day trips to escape the city when I lived in London.
The Princess of Wales conservatory was especially interesting with all the different zones and levels, including under the water. We saw that plus the Palm and Temperate houses, and points in between.
Here is just a small sample of some of the interesting plants and other life we saw.
The plant houses are architecturally interesting and the landscaping in between buildings is also great. There are also art displays and sculpture around.
