The three students were trapped on the island after the tide came in shortly before 12.30pm.
A passer-by on the shore spotted the group and dialled 999 for assistance. Galway RNLI’s lifeboat was subsequently called to the scene and arrived within 10 minutes.
The students were completely surrounded by water when the lifeboat arrived to assist them on board. They were then taken to Galway Docks in the city, where they are staying. They did not require medical assistance.
The lifeboat crew on this callout were helm Sean King, Cathal Bryne, Greg Cullen and Olivia Byrne, who said: “This highlights the dangers of going out to Hare Island when the tide is coming in.
“These young men got completely cut off in a short space of time. Luckily a diligent observer on the shore came to their assistance and contacted the emergency services straight away.”
