The tree has a circumference of about 44 feet (13 metres) and has a hollow trunk, making it the second-widest individual tree in the UK, only surpassed by the significantly older and much less-intact Marton Oak in Cheshire.
[6] The farm offers pre-booked private tours of the tree.

The tree has now been fenced to protect the roots from soil compaction.
[8] The Bowthorpe Oak is featured in The Guinness Book of Records and was filmed for a short TV documentary about its size.
