Tourists are being promised giant, scraggy sandstone cliffs and unspoilt bushland as part of a new 300-kilometre bushwalk south-west of Sydney, stretching from the Blue Mountains to Mittagong.
It is part of a bold new plan being developed by Wollondilly Council to tap into the region's tourism and economic potential.
Deputy Mayor Matt Gould said the council adopted an ambitious prospectus at a meeting this week to make the walk world-class.
"Most people, when we talk about this, are excited," he said.
"It links the Wollondilly, Wingecarribee, and Blue Mountains, making it a regional project that could really be a transformative boost for the local economy."
The circular walk includes Warragamba, through the back of the Sydney water catchment to Oakdale, then Thirlmere Lakes to Buxton and on to Mittagong, back through to Yerranderie and up the western side of the dam to Wentworth Falls.
"Most of the trails already exist, the project would connect the tracks and ensure they are clearly marked." Cr Gould said.
He also hopes the trail shines a spotlight on the old silver mining town of Yerranderie.
Once a thriving silver mining town, most of its jobs were lost in a national strike in the 1920s.
The town was further isolated from Sydney when the catchment was filled to create Warragamba Dam.
A wealthy benefactor bought the town from a mining company, and together with a small group of locals they have dedicated their lives to preserve its old buildings.
Some of the walk would cross land identified as part of the catchment and the council is negotiating with state authorities to gain access.
The council expects the project would cost about $3.7 million including improvements to roads, parking, and other amenities.
