Work is underway on a major upgrade of national park walking tracks along the cliff tops between Wentworth Falls and Katoomba.
NSW Environment Minister Matt Kean was in the Blue Mountains on Friday to talk with National Parks and Wildlife Service walking track teams carrying out the work, and to visit some of the areas to be upgraded.
Work has begun in the national park at Wentworth Falls, with the full upgrade expected to take four years to complete.
David Crust, the Blue Mountains director of the NPWS, said they would be adding in a few missing links to walking paths between Wentworth Falls and Katoomba, but mostly they would be improving the quality of existing tracks.
In February the state government announced it would spend $10 million on a "significant upgrade to the 13.6 kilometre grand cliff top walk".
"The changes will include improved walking tracks, better visitor infrastructure and facilities, and upgrading of access to iconic lookout points including mobility impaired access standards," Mr Kean said.
The grand cliff top walk links a series of existing tracks and is accessible from multiple locations, providing the opportunity for visitors to tailor the length of walk and to create a multi-day itinerary.
The walk also provides access to many sidetracks, which offer a variety of experiences and opportunities for all park visitors.
Govetts Leap at Blackheath is one of the iconic lookouts in the Mountains set to be upgraded with accessible paths, toilets with disabled access, and improvements to the carpark.
"The investment recognises the importance of the tourism economy in the Blue Mountains and will provide for better and safer visitor experiences across the Blue Mountains National Park," Mr Kean said.
