Did you know that you can actually take magic lessons in a castle, or sign a wall in the cafe where J.K. Rowling began to write the famous series? Potterheads who love history, fun book and movie facts, and endless amounts of Harry Potter memorabilia should — no, must — visit these themed spots all over the world.
Richmond Park is one of my favourite place to visit. Take a picnic, a camera and some good walking shoes. Explore. It's beautiful all year round and each season gives the park a different personality. The deer roam free and it's quite wonderful to get close to them (not too close mind, they are dangerous and you don't want to scare them).
Maltby Street Market: This small market is one of London’s best hidden gems. Every Saturday, local producers sell their street food under the railway arches in Bermondsey. Make sure to get there before lunchtime, as most stalls wrap up in the early afternoon.
