Some tracks can be hard to find, a few trees obstruct paths and certain areas turn into a swamp. Better ride for summer than winter

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.

The best way to find the trails is the Tuesday group Ride meeting at the car park at 7pm every week all welcome.

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

A unknown way to get into Bourne woods. Saves dealing with the busy car park.
