I had a bit of trouble finding what is left of the long barrow as it didn’t show on the O/S map I was using! For those in a similar situation, this is how you find it:
Continue north along the road which runs past the nature reserve / field containing the Lambourn Seven Barrows. In a short while, at the point where the road bends to the right, there is a parking area on the left. Park here. To the west you will see a public right of way leading up to a small wooded area. This is where you will find the remains of the barrow. There is next to nothing to see although there is a large flat stone next to a tree trunk right next to the path – just before you reach the gate. No doubt this must once have been part of the barrow?
