Pagers sounded at 1.58pm after a call was placed to the coastguard reporting two people stranded at the base of the cliffs just east of Howth’s East Pier.
Volunteer crew members launched the inshore lifeboat within 12 minutes of getting the call and proceeded to the area, where they quickly located the casualties.
Both were taken aboard the lifeboat and checked over and were found to be unharmed and in good spirits as they were returned safely to shore.
They confirmed that they were tourists visiting the area and got caught out by the incoming tide while walking at the base of the cliffs.
Speaking following the callout, lifeboat helm Killian O’Reilly said: “We were delighted to assist the tourists after they found themselves in difficulty.
“They did the right thing and called for assistance and remained calm. As visitors to the area they were unfamiliar with the tides and location.
“We were pleased to drop them back ashore safe and sound and hope they enjoy the remainder of their visit to Ireland.”
