Part of the Raad Ny Foillan was closed on Wednesday after a potential explosive device was found close to the footpath.
Gates, stiles and entrances were taped off between the Sound Café and The Chasms after the ordnance was discovered near the path.
However, the device was swiftly dealt with by a military explosives ordnance disposal team which travelled over from the UK to deal with the Second World War munitions.
Posting on social media on Thursday morning, Isle of Man Coastguard said: ‘We're pleased to report that the footpaths around Spanish Head that were closed yesterday are now open again.
‘Earlier this morning, UK Military Ordnance Disposal successfully dealt with some WW2 munitions which had been found yesterday afternoon in the area of the Raad Ny Foillan on Spanish Head. Our thanks to the member of the public who reported the item.
‘If you find an unusual/suspicious object or any ordnance in a coastal location, please call 999 and ask for Coastguard.’
Posting on social media on Wednesday, Port Erin Coastguard Rescue Team said: ‘Ordnance found on Raad Ny Foillan footpath on the Spanish Head Peninsula.
‘All footpaths between the Sound Cafe and The Chasms are taped off with red and white tape and are closed until the ordnance is dealt with.’
It is the third year in a row that ordnance has been found in the Spanish Head area, resulting in controlled explosions.
The area around Spanish Head was used for military training during the Second World War, which accounts for remaining mortar rounds occasionally being uncovered due to coastal erosion. Items found are usually mortar shells, although the ordnance discovered last year was thought to have been a submarine flare.
