It is a walled deer park of around 700 acres (280 ha) in area and has been open to the public since 1894. The A308 road and the River Thames form its boundaries. North of the A308 is the better-known Bushy Park. The Royal Mews still graze some of their horses on the park during the summer months.
One of the main features of the park is the Long Water which runs roughly eastward from the back of Hampton Court Palace. At the eastern end is the Golden Jubilee Fountain.
The annual Hampton Court Flower Show is held in 25 acres (10 ha) of the Home Park. It is organized by the Royal Horticultural Society and began in 1990. Many prefer it to the better known Chelsea Flower Show because there is more space, and plants and equipment can be bought at the show. As it is the world's most popular event of this type extensive traffic jams can build up. The show has sometimes been criticized for risking damage to historic features in the park.
