Hire a bike from the Ladbroke Grove central docking station. Nearby is a very famous little park in London. In the film Notting Hill, Rosmead Gardens is where Julia Roberts and Hugh Grant hop over the fence to walk around. Unfortunately, the garden is very private so you can only catch glimpses from the gate.
The next stop is Holland Park and more specifically a tiny little park in the centre of it called Kyoto Garden. This was created as part of the 1991 London Festival of Japan and provides Japanese-style gardens.
Afterwards, pedal onwards to Hyde Park. From the Serpentine bridge you'll have incredible views of London. Once you reach Lancaster Gate, take some time to try to spot the Hyde Park Pet Cemetery. Looking through the railings you should be able to spot the tiny Victorian era tomb stones with messages dedicated to beloved pets.
Finally, the route continues down towards Chelsea Physic Gardens. You'll need to dock your bike on the King's Road in front of the Royal Avenue House. From there it is a short walk down to the gardens through a very nice part of London.
The Chelsea Physic Gardens are the oldest botanical gardens in the UK. Note that there is an entry fee for the garden and it isn't always open to the public so it's worth checking their website before your visit.
As an alternative, very near here is also the Royal Hospital Grounds and the National Army Museum. Both are worth of a visit if you are in the area with some time to spare.
