14th of May) then here are some directions that may be of some use.
Coming South on the A19, as you climb up over the Tees fly -over look for
the left exit for the A66, Darlington, Teesside Airport and Stockton
directions. Join the A66 for Darlington, you will see signs for Preston Hall
Museum. Travel along the A66 passing the Tees Barrage/Teesside Park signs,
keep ahead across the river, ignore the first Stockton exit until you see
signs for A135 to Yarm and Preston Hall Museum, Butterfly World and Teesside
Airport. Turn left toward Yarm and the main entrance to the park is on your
left about 1 mile ahead.
Travelling from A1M or A167 head for Darlington and take the A66 for
Teesside and Stockton. Pick up the A135 to Stockton and Yarm and head
towards Yarm and Preston Park.
