Guisburn Forest
Guisburn forest contains two smallish quarry areas which have held rounds of the NAMBs trials series. There are a variety of drops, gaps and other obstacles to keep you amused along with some other wooded sections.
There is also a short downhill course in the forest. Guisburn forest is located in Lancashire. Check out MBUK (October 2000) for more info and pictures. It has a picture of Aidan Bishop in a swimming pool on the front cover.
