Holland Park is an absolute delight at any time of year, and this idyllic spot is a very short walk from Olympia's venues.
The park opened to the public in 1952 and is the largest in the Royal Borough of Kensington and Chelsea.
There is a huge variety of spaces, with semi-wild woodland, a Japanese garden and geometric formal gardens. Each carefully cultivated area provides a unique and enchanting environment in which to relax and unwind.
In the summer months you can even watch opera in the delightful open air theatre, surrounded by the remains of Holland House. Most of this huge mansion was destroyed by bombing in the 1940s but it has been reborn, with different parts providing the setting for the café in the Orangery and the Marco Pierre White restaurant, The Belvedere. There's even a youth hostel.
Holland Park should be top of your list of things to do when visiting Olympia London.
