The Irish Naturist Association recommends these destinations for nude beach lovers...

Silver Strand Beach, Barna, County Galway

Silver Strand is about four miles away from Galway and naturists flock to the small beach just off the main beach. To access the nudist beach, walk for about 20 minutes on the stone path. The perfectly quiet beach is in a beautiful setting and well worth the walk to get there.

Roundstone, County Galway
This beach, which is surrounded by stunning scenery including rivers, beaches lakes and mountains, is off the Galway - Clifden road at the exit marked Roundstone. Naturists must walk the full length of the beach and then take a path up the hill to a gate. Another path leads across the headland from the gate to a sandy cove which is barely visible until you are nearly on top of it.

West Cork, County Cork
Stunning West Cork offers dozens of quiet and secluded coves. Perfect destinations include the eastern and western sides of Clonakilty Bay, Dunowen with its rocky cliffs, Dunny Cove and Sands Cove, while Glandore includes the famous rocky Prison Cove that is a long-accepted haven for naturists.
Naturists can also explore Simons Cove, Roaring Water Bay, Lough Hyne and the magnificent Beara peninsula which have many deserted beaches for nude beach lovers.

Corballis, Donabate, County Dublin
Corballis is just off the busy M1 motorway which links Dublin to Belfast. The beach can be accessed by driving through Donabate to the beach itself. Naturists should park as far down the beach as possible but be careful of the soft sand when parking. Once parked, just walk down the beach for about 20 minutes until you come to the secluded area. Another option is to drive towards Donabate but turn right at the signpost for the Island Golf Club and Corballis Golf Club. There is a small lay-by just before the entrance to the golf club to park. Walk through the gate and follow the path over the dunes until you reach the beach. Once there, turn right and walk for another 15 minutes to the naturist area.

Brittas Bay, Co. Wicklow
Brittas Bay is one of the best naturist beaches on the east coast. It is certainly the most popular. The main beach is clothes-only and attracts campers and caravans at the weekend and during national holidays.  The naturist beach, which is some two miles south of the main beach, is long and sandy, backed by large dunes but with a stony strip between the dunes and the water.
To get there, take the Junction 7 of the main Dublin-Wexford M11 south motorway, nine miles south of Rathnew. Follow the signpost for Jack White’s Cross and Pub and take the road until you can go no further. Take the turn right and follow the coast for about 2 miles until you come to an area marked Buckrooney. This area is gated and once you are through the gate, turn left and walk on the beach until you reach the fencing area on the dunes. This area is for naturists, but nude beach goers should not venture outside the protected area as the beach is popular with clothed families.
