@WhereinDublinIf you’re planning a beach day around Dublin and wondering where you can enjoy clear water, fresh air, and spotless sand, you’re in the right place. Dublin might be famous for its city life, pubs, and culture, but it also has some stunning beaches where you can escape for a swim, a walk, or a quiet moment with nature.
From my own personal experience, the beaches around Dublin are surprisingly clean and well-maintained, especially compared to what most people expect from a capital city coastline. The secret is knowing which ones consistently top the cleanliness charts, have Blue Flag awards, and are regularly tested for water quality.
Let’s jump into the details so you can find the cleanest beaches in Dublin, understand what makes them so pristine, and pick the perfect spot for your next visit.
Why Beach Cleanliness Matters
Clean beaches aren’t just about looks, they’re about health, safety, and sustainability. When a beach has clean water and well-kept sand, it means the local council and the community are actively protecting the environment.
Here’s why cleanliness should be your top concern when choosing a beach in Dublin:
Water quality affects your health: Polluted water can carry bacteria that cause rashes or infections.
Clean beaches protect wildlife: Litter and waste can harm sea birds and marine animals.
A tidy beach enhances your experience: Nobody enjoys stepping on trash or seaweed clumps while walking barefoot.
It reflects local pride: Dublin’s clean beaches are often the result of consistent community effort.
So, if you’re after clear blue water and sand you can sit on without hesitation, let’s explore which Dublin beaches meet those standards.
The Blue Flag Standard
Before naming the cleanest beaches, it’s worth understanding what the Blue Flag award means. The Blue Flag is an international eco-label given to beaches that meet strict standards for cleanliness, safety, and environmental management.
To earn a Blue Flag, a beach must have:
Excellent water quality
Clean, well-maintained sand
Proper waste disposal facilities
Lifeguards or safety services during the bathing season
Environmental education programs
Dublin has several Blue Flag beaches, which makes finding a clean spot much easier.
1. Portmarnock Beach (Velvet Strand)
Why It’s Considered the Cleanest
Portmarnock Beach, known locally as Velvet Strand, is one of Dublin’s cleanest and most beautiful beaches. It consistently earns the Blue Flag award thanks to its excellent water quality and spotless sand.
The beach stretches for nearly 5 kilometers, which means it rarely feels crowded. Local authorities regularly clean it, and it’s also popular among people who care about keeping it tidy.
What You’ll Love About It
Soft, golden sand perfect for long walks.
Beautiful views of Howth Head and Ireland’s Eye.
Regular water testing ensures safe swimming conditions.
Lifeguards on duty during summer months.
Easy access by DART or bus from the city center.
Best Time to Visit
Visit early in the morning if you want peace and quiet. During summer weekends, it’s popular, but it still stays relatively clean thanks to responsible visitors.
2. Seapoint Beach
A Compact Gem with Excellent Water
Seapoint Beach, located between Blackrock and Monkstown, is a favorite among Dubliners for quick dips. It has a Blue Flag award and is known for its exceptionally clean water.
The beach itself is smaller compared to Portmarnock, but what it lacks in size, it makes up for in charm. The sand and rocks are kept neat, and the water quality here consistently tests as excellent.
What Makes It Stand Out
Easily accessible from the DART line.
Great for swimming and paddleboarding.
Frequent cleaning and clear signage about water safety.
Calm, shallow water ideal for families.
Pro Tip
Visit during high tide for the best swimming experience. Low tide exposes rocks, but the surrounding area stays clean and walkable.
3. Killiney Beach
Where Natural Beauty Meets Cleanliness
Killiney Beach feels like something out of a postcard. It sits along Dublin’s south coast and offers a stunning backdrop of rolling hills and calm blue water.
Killiney regularly ranks high in cleanliness reports by EPA Ireland (Environmental Protection Agency). Its pebbly shore stays clean thanks to frequent maintenance and an active local community that organizes cleanups.
Highlights
Crystal-clear water ideal for sea swimming.
Picturesque scenery that feels far from city life.
Clean facilities and well-maintained paths.
Beautiful coastal walks connecting to Dalkey and Bray.
From My Own Personal Experience
Based on my overall experience visiting several Dublin beaches, Killiney offers that perfect mix of clean water, breathtaking views, and peaceful surroundings. It’s one of those places where you can sit for hours and just watch the waves without worrying about litter or mess.
4. Burrow Beach (Sutton)
A Local Favorite That Stays Clean
Tucked between Sutton and Howth, Burrow Beach is often overlooked — but that’s part of what keeps it so clean. It’s smaller and less busy, which helps maintain its natural beauty.
Regular monitoring by Fingal County Council keeps the beach in top shape. The sand is fine and soft, and the water quality has been consistently rated “excellent” in recent years.
Why You Should Visit
Quieter atmosphere than larger beaches.
Excellent water quality for safe swimming.
Stunning views of Ireland’s Eye.
Great for picnics or peaceful walks.
Extra Tip
Since it’s less crowded, Burrow Beach is perfect for people who want space without compromising cleanliness. Bring your snacks and enjoy a calm, scenic afternoon.
5. Dollymount Strand (Bull Island)
Dublin’s Wild, Natural Beach
Dollymount Strand, stretching across Bull Island, is one of Dublin’s most famous beaches — and also among its cleanest. It’s a UNESCO Biosphere Reserve, which means it’s protected for its environmental importance.
The city has worked hard to keep this long stretch of sand clean, despite being a popular spot for walkers, kite surfers, and swimmers. It’s regularly cleaned, and water tests are conducted to ensure quality.
Why It Deserves Attention
Blue Flag status for water cleanliness.
Vast open space — over 5 kilometers long.
Natural dunes and bird habitats make it special.
Frequent clean-up efforts by volunteers and local groups.
What to Expect
The atmosphere is slightly wild and untamed, but that’s what gives Dollymount its charm. The wind, waves, and open space make it ideal for anyone who loves nature in its purest form.
6. Skerries South Beach
A Family-Friendly, Pristine Spot
Located in North County Dublin, Skerries South Beach is another Blue Flag winner and a top contender for the cleanest beach around the city.
It’s known for its calm waters, wide sandy shore, and family-friendly vibe. The town of Skerries itself is charming, and the locals take pride in keeping their beach spotless.
What You’ll Find
Excellent water quality and clean sand.
Lifeguards during summer.
Smooth access for families and children.
Beautiful views of the Skerries islands.
Why It’s Worth the Trip
Though it’s a bit of a drive from the city center, Skerries Beach rewards visitors with a mix of clean surroundings and small-town warmth. It’s ideal for families looking for a safe, well-kept place to spend a day by the sea.

Tips for Keeping Dublin Beaches Clean
Even the cleanest beaches stay that way because people care. You can help maintain their beauty by following simple habits:
Take your litter home. Avoid leaving bottles, wrappers, or cigarette butts behind.
Use the bins provided. Dublin councils have placed bins at most beaches.
Join local cleanup events. Groups like Clean Coasts organize regular volunteer cleanups.
Avoid using single-use plastics. Bring reusable bottles and containers.
Respect wildlife. Don’t disturb birds, seals, or their habitats.
These small actions help keep Dublin’s coastline safe and clean for everyone.
Hidden Clean Beaches Worth Exploring
If you’re open to discovering less popular but clean coastal spots, try:
White Rock, Dalkey: A small, rocky cove that’s kept clean by locals.
Loughshinny Beach: Peaceful and scenic, with clear water and fewer visitors.
Balcarrick Beach (Donabate): A quiet stretch that’s tidy and great for long walks.
These aren’t as famous as Portmarnock or Killiney, but they often surprise visitors with their cleanliness and calm.
Final Thoughts: Where’s the Cleanest?
So, where in Dublin is the cleanest beach?
If you want a straight answer — Portmarnock Beach (Velvet Strand) takes the crown. It ticks every box: clean sand, excellent water, Blue Flag certification, and easy access. It’s the kind of beach where you can spend the whole day without spotting litter or worrying about the water quality.
That said, beaches like Seapoint, Killiney, and Burrow are just as worthy depending on what kind of day you want — quiet, scenic, or social.
Dublin’s beaches prove that city life and clean nature can exist side by side. With care, respect, and community effort, these coastal gems continue to shine.
So grab your towel, sunscreen, and a bit of curiosity — and go enjoy Dublin’s clean, fresh, and peaceful shoreline.
