Emergency services were called around 1:20pm on Wednesday, with reports of one person with abrasions, a foot injury and a possible knee injury, and was unable to walk.

Two other people were reported to have had minor injuries.

A NSW Ambulance spokesman said it could be some time for paramedics to get to the patient, as the walk was more than six kilometres and could take around one-and-a-half hours to reach the patient.

The popular tourist and swimming spot is located on a dangerous rock shelf near Burning Palms Beach, and has been the subject of many incidents and even deaths in the past.

The NSW National Parks website does have a risk-level rating, however for Wednesday it was given a "low" danger score.
