A man is in a critical condition in hospital after falling from a rock ledge near the Figure Eight Pools in the Royal National Park on the weekend.

Emergency services were called to the remote site about 10.30am on Sunday, and found a man believed to be in his mid-20s with cuts to his chest and head injuries.

Paramedics first arrived on foot to treat the man, before an ambulance helicopter winched him aboard and flew him to St George Hospital, where he remained in a critical condition on Sunday afternoon.

It is understood the man diverted off a main track and was trying to walk along a cliff rock ledge in a cove close to the Figure Eight Pools, when he fell onto rocks.
