Richmond Park is the most visited royal park outside central London, with 4.4 million visits in 2014. The park is enclosed by a high wall with several gates. The gates either allow pedestrian and bicycle access only, or allow bicycle, pedestrian and other vehicle access. The gates for motor vehicle access are open only during daylight hours, and the speed limit is 20 mph. The gates for pedestrians and cyclists are open 24 hours a day apart from during the deer cull in February and November when the park is closed in the evenings. Apart from taxis, no commercial vehicles are allowed unless they are being used to transact business with residents of the park.
