Park in the car park (SK188.138) at Croxall Nature Reserve which is on the A513 a little further on from the National Arboretum.
Directions to Noon Column: Walk out of the car park and turn left through a kissing gate into the Nature Reserve. Follow the broad path for about 10 minutes when you will see the Noon Column on your left.
This walk takes in the nature reserve and the National Arboretum so you need to take care when moving from one to the other as it includes a busy road!
