Good jump and berms section in the woods just outside Austerby. Not too technical so fine for beginners if the weather has been fair.

Bourne Woods is an ancient woodland with winding paths, ponds and captivating wildlife such as kingfishers and herons can be seen. There’s an excellent cycle trail through the woods linking Bourne with Hanthorpe.

Plenty of trails to hunt out that have been built up over the years. Forestry can make it hard to link them together at times
