Sherrardspark Wood (grid reference TL230139) is a 74.9 hectares (185 acres) biological site of Special Scientific Interest in Welwyn Garden City, Hertfordshire.

[1] It is located to the north west of Welwyn Garden City and is an ancient woodland consisting mainly of Sessile oak and Hornbeam.

It is used by dog walkers, joggers, cyclists, and horse riders.

[2][3] There are a number of walks through the wood, one of which follows 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.
