London can get extremely crowded during the weekends, making the weekdays the best time to go on a London walking tour. The attractions can be explored any time of the day, as each time provides incredible views. Daytime tours offer better visibility so you can fully appreciate the architectural details, while evening tours provide a unique atmosphere as attractions get illuminated. Consider your preferences and book the time that suits more to your wishes. Remember that the weather tends to be unpredictable, so it shouldn’t be a significant factor when deciding on the tour time.
