The woman, who was not thought to have been seriously injured during the incident on Monday, came to rest just one metre from a sheer drop down to the rocks and beach below.
And the Fire and Rescue Service said it was lucky she had been wearing a cycle helmet to prevent any serious head injuries.
Emergency services were called to the scene at Grève de Lecq at around 11.30am. They discovered that the woman had fallen from her bike and tumbled around 20 feet down an embankment on the St Mary side of the bay. It is thought she was stopped from falling any further by the vegetation.
A crew from the Western Fire Station and a specialist rescue unit attended alongside the fire duty officer, the States police and the Jersey Ambulance Service.
In a statement, the Fire and Rescue Service said: ‘On arrival crews were met by the senior paramedic on scene whose description of the incident and casualty’s condition meant that we could get to work quickly with the appropriate height rescue equipment. After securing the casualty, crews from States of Jersey Ambulance Service and Jersey Fire and Rescue Service wearing height rescue safety systems were able to transport the casualty on to a rescue stretcher safely to the ambulance.
‘The casualty was later transported to hospital for an assessment. Whilst her injuries are not expected to be serious, it is without no doubt that because she was wearing a cycle helmet this really did prevent any serious head injuries occurring.’
Station commander Ryan Hall added: ‘It was absolutely the right tactical decision working closely with ambulance paramedics using our safety systems. The safety of the casualty and our crews meant that we could work to the best and safest outcome. The terrain was difficult and within a one-meter a sheer drop from the edge to a further 20-meter drop to the rocks on the beach below. Thankfully the casualty was wearing a cycle helmet that prevented any serious injuries to her head.’
