Echo Point in Katoomba will be temporarily closed to the public from midday today (April 1) until further notice.
This follows the closure of council's 56 formal playgrounds, skate parks and barbecue facilities.
Non-essential travel to regional NSW areas, including the Blue Mountains must also be cancelled, following the latest Public Health Order from the NSW Government.
Blue Mountains mayor Mark Greenhill said: "While these new closures and restrictions seem extreme, they are totally and unequivocally necessary to protect the health of our staff and our community.
"Council is following the directions and advice of the NSW government. This approach mirrors our own request to the state government in regards to restricting the number of visitors coming to areas like the Blue Mountains during this period of crisis," he said.
"I've been saying for some time that we needed more decisive and swifter action to protect our communities, and particularly the most vulnerable among us, and I am relieved to see the NSW and Australian Governments are starting to implement that action now.
"It is what we need to weather this storm as safely and quickly as possible."
