Sherrardspark Wood (grid reference TL230139) is a 74.9 hectare (185.1 acre) biological and geological, site of Special Scientific Interest in Welwyn Garden City, Hertfordshire. The site was notified in 1986 under the Wildlife and Countryside Act 1981 and is currently managed by the Country Trust as a Nature Reserve.
It has a number of walks through the wood, one of which used to follow the disused Luton/Dunstable branch line from Welwyn Garden City railway station. This line closed in the 1970s and runs from the White Bridge on Digswell Road west and then north to the Great North Road next to the A1(M) motorway, close to the Red Lion pub. The trail continues from Ayot St Peter on the other side of the motorway along Ayot Greenway.
