Portrane Beach in Dublin is actually two beaches in one - the big sandy Portrane Beach and the smaller stony Tower Bay. Both offer different vibes, with Portrane Beach being great for a leisurely stroll or swim, while Tower Bay is more secluded and suited for experienced swimmers. Parking can fill up fast on sunny days, so get there early if you want a prime spot. And don't forget to check out nearby attractions like Donabate Beach, Newbridge House, and Ardgillan Castle for a full day of exploring!
