There used to be a section of low-level boardwalk crossing a boggy section of the unofficial trail, but this was removed by the Forestry Commission in October 2005. The reason for this is that the Forestry Commission have a policy of removing or putting beyond use any man-made structures on unofficial trails. This protects them against liability claims, as legally it's much harder to argue that the landowner is responsible if you injure yourself on a "natural" trail. The Forestry Commission are happy to have wooden structures on official trails, and have built these at venues like Afan Forest Park and Cwm Carn.
