Sit aloft the famous Walkie Talkie skyscraper in the heart of London, this stunning rooftop garden provides the best 360-degree views of the city’s iconic skyline. The Gardens opened in 2015, with the aim of creating a green space in the heart of the city. The gardens feature some exotic plants from across the world, but honestly nothing too spectacular. I think what had me in awe was the sheer strangeness of it all. An undeniably special experience, even more so at sunset with a tasty cocktail at the Fenchurch terrace bar. Entry is free, but you will be required to book a ticket so be prepared.
