It is distributed among dozens of individually designed cultural landscapes. These landscapes were planned for recreational purposes, at first by wealthy gentlemen on their private estates and later by community based trusts who administered grants from the NSW Government. There exists a full range of original construction types and track fabric and associated features such as shelter sheds, wells, railings and signage from the 1870s private tracks to the efforts of the Blue Mountains National Park Trust in the 1960s. The blending of man-made and natural features in track construction was done in ways that reflect the aesthetics, technology and environmental values of the time. Many of the constructed features transcend their purely utilitarian functions and have considerable aesthetic appeal. The solutions of the early trustees and track makers to complex problems of design, particularly drainage issues and the use of stone have significant research value today. Due to the proximity of the reserves to Sydney and the early provision of mass transport links between Sydney and the Blue Mountains, the region's walking tracks have been the most significant facilitators of contact between urban Australians and the natural environment. The Blue Mountains tourist industry grew largely to service people who desired an engagement with nature on the walking tracks. The tracks have been an important factor in the growth of conservation values in the community. Walkers have left
