One of the best gardens in England is the Alnwick Gardens in Northumberland. They're located close to the old castle. The majestic cascade and fountains, which are among the most modern in Britain, provide tourists with breathtaking spectacles. There is music to go along with the displays. However, there is much more to see, such as a sizable rose garden paired with numerous clematis species, which are in full bloom from mid-July to early August. One of the biggest in the world, The Treehouse is a great spot for kids to hang out and has amazing dining options as well as skywalks. The Serpent Garden, which has topiary and water sculptures, the Bamboo Labyrinth, and the Poison Garden are a few of the attractions.
