Road cycling is no stranger in Isle of Wight and Smithfield. Mountain bike trail riding is.  With the birth of Windsor Castle Park came the addition of an off-road cycling trail.  The minimum improved bike trail is designed to challenge/educate a new trail cyclist and still provide a good workout for our more experienced riders. The bike trail access point is well marked from the main parking area off of Jericho Road. Follow the signs near the Dog Park to enter the trail. As a reminder: Bicycles are not allowed on the walking trails of the Park. Happy Trails, riders! Bike Trail hours: Dawn to Dusk.
