The Howth Cliff Walk is perhaps one of the most epic experiences in all of Dublin. Tracing the Howth Peninsula, this trail is a treasure trove of hidden coves and remote beaches hugging the shoreline.

Still, this is the place to find the best wild sea swimming spots in Dublin for those up for the adventure.

Just bear in mind that, to access most of these beaches, you’ll have to work your way down the cliff – suitable footwear is strongly recommended, as well as water, sunscreen, and any other essentials.
