A major upgrade of Echo Point is nearing completion.
Work has continued while the lookout has been closed due to COVD-19 restrictions, with an anticipated finish date of August.
The upgrade will include a new amphitheatre and the reopening of the Prince of Wales Lookout, which has been closed for 10 years.
It will also feature an accessible, night-lit boardwalk connecting the lookouts, amphitheatre and council's Visitor Information Centre.
Last month a 130-tonne crane placed part of the new walkway into place.
"In early December 2019 we had thousands visit Echo Point Lookout to see the remarkable sight of bushfires burning in the Ruined Castle fire," said Blue Mountains mayor Mark Greenhill.
"Then in March this year, council had to take the extraordinary step of closing Echo Point Lookout, and our visitor information centre, due to the COVID-19 pandemic.
"Redevelopment at the site is now nearing completion and council is looking forward to removing the construction hoarding and reopening the precinct, fully, for visitors."
The mayor said a highlight of the upgrade will be the creation of the gathering space, or ampitheatre, that has been designed in consultation with Gundungurra and Darug traditional owners.
"The place we now call Echo Point has been of great significance to Gundungurra and Darug people for time immemorial, and is linked to creation stories which connect it to other sacred stories across the continent. It is also one of the most visited sites of Aboriginal cultural significance in Australia," he said.
"We want the special value of this place to be appreciated by everyone, so that they take away a deeper appreciation of the complexity and beauty of Aboriginal culture."
The mayor said it is "also great that we will be able to reopen the Prince of Wales Lookout that has been closed for 10 years, and provide a 140-metre accessible, night-lit elevated walkway".
Council received matched funding from the federal government's National Stronger Regions grant program for the project. A federal government Safer Communities Grant also funded CCTV and other security upgrades, including bollards and evacuation signage, at the site.
