If you like botany or plants etc. Kew Gardens is one of the
best. I spent one whole day there exploring all of it but it
was not enough. It is near Richmond which is close to London.
There are many glass houses that host plant species from variety
of countries and continents. It also has a humid glass house
to host plants from the Mediterranean environments.
There are a few very old trees with huge barks.
It’s a nice place to visit in summer – relaxing
with family, having a brunch outside and taking a nap below
