The longer daylight hours also allow for more extensive exploration of the Ruislip Woods National Nature Reserve. Additionally, local events and festivals are more common in the summer, offering a chance to experience the community spirit.For those looking to avoid the busiest tourist periods and potentially find better value on accommodation, visiting in May, early June, or September is a good option.
