City Lights Evening Trail

Follow a series of cryptic clues on a secret journey across London. Each clue, sent by text, leads you to a new location - but you'll have to solve one clue before receiving the next. Starting just a stone's throw from the boundaries of Londinium, you'll pass the ancient Roman wall and descend into the maze of the City, stopping at a number of taverns along the way. Walks cover two miles and last two to three hours. Visit the website for details.
