Leave Cheam station through the exit from the platform served by trains from London. Ride straight ahead along Station Approach and turn right at the T-Junction into Upper Mulgrave Road. At the end of this road, turn right into Sandy Lane (signposted 'Cheam Village'). Pass under the railway and take the second left (Kingsway Road). At the end, turn right into Anne Boleyn's Walk. At the junction with the main Ewell Road, use the toucan crossing to the left and then turn left, following a cycle track through some trees. To your right, there is an occasional view of Cheam Park through the trees. Continue to the gate of Nonsuch Park.
Enter the park and ride along the drive for about 300 metres, until it is blocked by a barrier. Turn right towards Nonsuch Park Mansion. Ignore the right fork towards a car park and follow the path straight ahead and then left around the front of the Mansion, where there are cycle parking stands, a café and toilets. The gardens lie behind the Mansion.
The Nonsuch Mansion, an 18th century house, itself possibly built on the site of the Keeper's Lodge to Nonsuch Palace's Little Park, was rebuilt by architect Jeffry Wyatville in the picturesque gothic style in 1802-6. The present house has a castellated brick wall down one side and the gardens, which were partially laid out by Thomas Whately c.1830, feature a rose walk, sunken shrubbery, trees and flowers. The Friends of Nonsuch open the service wing of the Mansion in the afternoon of the 2nd and 4th Sundays of each month plus bank holidays from April to September.
