Beaches in Donegal, Galway, Sligo, and Cork also made the list.

A beach in Mayo has been named as the best place to swim in Ireland and the UK, and deservedly so. The stunning Keem Bay in Achill was named as the top place to go swimming in the sea by Ocean Bottle, a company that manufactures reusable water bottles with a commitment to collecting the equivalent of 1,000 plastic bottles from the ocean for every bottle sold. https://www.instagram.com/p/Cbf2z8gMU1O/ The list of beaches was compiled following a study of average water quality across the past year, including the E.coli and intestinal Enterococci count, to first determine how safe the beach was for swimming. This was then cross-referenced with the location's Google Ratings and reviews, with any location with less than 100 reviews being removed.
