Based around the concept of a treasure hunt, HiddenCity offers a unique way to explore London. With a trail of curious clues sent via text message, teams are guided from famous institutions to hidden pubs and bars. There are a number of hunts to choose from including the Bright Lights Evening Trail, leading you from high to low, exploring riverside views and basement bars; the City Lights Evening Trail, delving into the city's history; and Bar Breaks, a great one for tourists with the likes of Trafalgar Square and The Mall encountered along the way. Whether you're a London expert or a first time visitor, these tours are fun for all and create the opportunity to discover hidden gems and test your local knowledge. Each trail offers a couple of pit stops along the way but feel free to add a few more to create your own pub crawl. Or, if you're feeling competitive, split into teams and race against the clock.
