The Caves of Maghera and Maghera Beach in Donegal, Ireland are a must-visit destination for any traveler looking to explore the stunning Irish countryside. Located a stone’s throw away from Adara, this sandy stretch lends ample opportunity for exploration and relaxation at the same time. Be sure to observe the warning posted about the caves before entering, as flooding can occur rapidly during high tide. When exploring the beach please also note that swimming is not allowed due to dangerous rip tides.
