Two defibrillators have been installed in Glenveagh National Park ahead of the busy summer season.
The life saving devices are located at the car park entrance and near the castle courtyard and tearoom.
Visitors exploring the park in the coming months are invited to familiarise themselves with the locations.
If an emergency occurs and there is a defibrillator nearby, ring 999 for the code to unlock the defib and operators will talk you through using the device.
