Police have found the body of a man missing in the Wollangambe River at Mount Wilson who drowned after becoming wedged in rocks in the canyon.
Media reports have named the man as 39-year-old Munib Dar from St Ives.
He was reported missing by a fellow canyoner about 5pm on Sunday.
Mr Dar lost his footing and disappeared about two hours earlier while canyoning with friends in Wollangambe Creek Two.
Blue Mountains Police Area Command officers started searching the water and surrounding areas, helped by specialist police attached to Police Rescue and PolAir, as well as NSW Ambulance.
The search was suspended at about 7pm on Sunday evening due to bad light, but it resumed on Monday.
By 11am on Monday, his body was found, submerged in water.
Police have been waiting for heavy fog to clear to winch him out by helicopter and were hopeful of clearer weather on Tuesday.
Blue Mountains Police Acting Inspector Lauren Martin told a media conference at the command post in Mount Wilson that the canyon's terrain was "quite difficult".
"There are parts where you are scrambling over rocks ... and [parts] where you should probably have flotation devices with you."

In January 2021, two women lost their lives while canyoning in a whirlpool in a different section of the Wollangambe river.
Serving police officer Kelly Foster, 39, and Yuanlei (Jenny) Qi were sucked into a whirlpool in Wollangambe Creek One while on a social trip with a bushwalking club. They drowned soon after.
Ms Foster died attempting to save Ms Qi, a 24-year-old international student.
The Deputy State Coroner, Magistrate Harriet Grahame, said the manner of death was "accidental drowning" by "misadventure, canyoning".
But Inspector Martin said on this occasion "there was no indication it was a whirlpool".
She said the man was climbing along rocks when he "lost his footing" and became stuck in rocks; adding there were some "parts [of the canyon] that dam up".
Inspector Martin told assembled media a friend had attempted to free Mr Dar from where he was stuck and then went up the river for help.
There was no phone coverage.
