Hyde Park in London is a massive green oasis in the middle of the city. Covering over 340 acres, it's like a breath of fresh air surrounded by Mayfair and Kensington Gardens. You can chill by the lake, known as the Serpentine, or check out Speakers' Corner for some lively debates. Don't miss the statue of Achilles or the Wellington Museum nearby. And if you're feeling fancy, take a stroll down Rotten Row, the famous riding track that cuts through the park. It's a royal hunting ground turned public playground, perfect for picnics, people-watching, and soaking up some nature in the heart of London.
