A day trip to Windsor is perfect if you want a mix of history, royalty, and a pretty riverside town. There are plenty of tours, and it only takes around an hour from London. Windsor Castle is one of the official residences of the King. You can tour the State Apartments, see St George’s Chapel, and wander around the charming streets filled with cafés and shops. It’s an easy and relaxed escape from the city that still feels full of British charm.
