211

After road tripping around Ireland’s west coast, I can confidently say County Mayo blew me away. The landscape here is pure drama—I’m talking about massive cliffs plunging into the Atlantic and mountains that look straight out of a fantasy movie. Plus, there’s Croagh Patrick Mountain towering over everything like a watchful guardian.

I spent an incredible week bouncing between lively Westport’s music-filled pubs and Achill Island’s wild beaches, and wow—these things to do in County Mayo made me fall hard for this corner of Ireland. From wandering through the fancy rooms of Ashford Castle (where actual royalty has stayed!) to watching the sunset paint the Atlantic golden, Mayo showed me what real Irish magic feels like. Let me share my favorite spots in this unforgettable slice of the Emerald Isle.

Best Things to Do in County Mayo

Looking for the coolest things to do in County Mayo, Ireland? Hike up Croagh Patrick, relax at Keel Beach on Achill Island, cycle the scenic Great Western Greenway, and explore the wild beauty of Ballycroy National Park. Whether you’re into adventure, nature, or breathtaking landscapes, these are the top attractions to visit in County Mayo.

1. Climb Croagh Patrick

Climbing Croagh Patrick is a rite of passage for many visiting County Mayo. Rising 764 meters over Clew Bay, this sacred mountain has drawn pilgrims for centuries. The hike starts near Murrisk, and while the path can get steep and rocky, it’s well-marked and manageable with proper footwear and pacing. Most hikers complete the round trip in about 2.5 to 3.5 hours.

I started early to beat the crowd and found the peaceful morning views unforgettable. There’s a small chapel at the summit, and on a clear day, the sweeping view of the bay and its many islands is worth every step. Even if you’re not religious, the experience is powerful—blending physical effort, natural beauty, and cultural history. Bring water, layer up, and take your time. Whether you summit or just hike partway, Croagh Patrick offers a rewarding outdoor challenge.

2. Surf at Keel Beach, Achill Island

If you’re into surfing—or want to try it—Keel Beach on Achill Island is a solid choice. The long sandy stretch faces the open Atlantic, offering consistent waves that suit both beginners and seasoned surfers. Conditions vary day to day, so there’s always something new to challenge you.

I rented a board and wetsuit from Achill Surf School & Activity Adventure Centre, just steps from the shore, and their team made it easy to get started. The vibe is laid-back, and the scenery is stunning—rugged cliffs rise at each end of the beach, and you might spot dolphins out beyond the breaks.

After an hour or two in the water, I warmed up with a coffee nearby and watched others carve through the waves. Even if surfing’s not your thing, Keel Beach is worth visiting for its raw, coastal beauty and open, windswept charm.

3. Cycle the Great Western Greenway

Covering 42 kilometers between Westport and Achill Sound, the Great Western Greenway is Ireland’s longest off-road cycling trail. It’s mostly flat and easy to follow, winding past mountains, bays, and quiet villages. The route once served as a railway line and now offers an incredibly scenic ride through County Mayo’s countryside.

I rented a bike from Westport Bike Hire, which made the process easy—they provided a hybrid bike, helmet, and a map of the trail. They also offer shuttle services if you want to cycle just one way, which worked great for my schedule. I stopped in Mulranny, where a small café had outdoor seating with views over Clew Bay.

The ride was peaceful, mostly free of traffic, and packed with scenery—rolling fields, distant peaks, and quiet coastal stretches. Whether you do the full route or just part, the Greenway is a relaxing way to experience Mayo’s natural beauty.

4. Explore Ballycroy National Park

Tucked away in northwest Mayo, Ballycroy National Park offers something different from the usual rolling hills—it’s home to one of Europe’s largest expanses of blanket bog. This wild and rugged park is a haven for nature lovers, with trails that cross wetlands, low mountains, and untouched landscapes.

I started at the visitor center, where staff helped me choose a short loop hike. Even from the trailhead, the views were incredible—layers of clouds over Nephin Beg mountains, with boglands stretching in every direction. Along the walk, I caught sight of birds I’d never seen before and even stumbled on a patch of sundews—tiny carnivorous plants. T

his place feels raw and remote in the best way. If you want a walk that gives you silence, scenery, and a deeper sense of Ireland’s natural heritage, Ballycroy delivers.

5. Walk Along Downpatrick Head

Standing on Downpatrick Head, with the Atlantic crashing below and Dún Briste rising from the sea, is a surreal experience. The cliffs are sheer and dramatic, offering panoramic views of the wild coast. I arrived early in the morning, and the breeze mixed with sea spray made the whole place feel almost mystical. This headland is not only beautiful but tied to Irish legend and history, adding depth to every step.

Paths lead you to several marked viewpoints, and interpretive signs share insights into the geology and folklore. I sat for a while near the main lookout, watching seabirds circle the sea stack. It’s peaceful but awe-inspiring, and you don’t need to be an avid hiker to enjoy it. If you’re into nature photography or just want to see the raw beauty of Mayo’s coastline, Downpatrick Head is a must.

6. Visit the Ceide Fields

Atop the rugged cliffs near Ballycastle, the Ceide Fields reveal one of the oldest known field systems in the world. This Neolithic site is over 5,000 years old and offers a rare glimpse into Ireland’s ancient past. What looks like an untouched bogland is actually layered with stone walls, enclosures, and dwellings hidden beneath the peat.

Inside the visitor center, I found detailed exhibits and a guided tour that made the history come alive. From the clifftop viewing deck, the Atlantic stretches endlessly, and on clear days, the views are incredible. It’s not crowded, which adds to the contemplative atmosphere.

Seeing how these ancient people lived and worked the land was fascinating, especially in such a windswept, remote spot. The Ceide Fields combine natural wonder with archaeological insight—one of the most unique and reflective stops in Mayo.

7. Enjoy Fresh Seafood in Killala

The coastal town of Killala is small, but its seafood offerings leave a lasting impression. Known for its harbor and fishing tradition, the village has a handful of pubs and restaurants serving up freshly caught fish daily. I grabbed dinner at the Village Inn, a laid-back pub known for its fish and chips and relaxed atmosphere. The portion was generous, the fish crispy and fresh—exactly what you want after a day exploring Mayo’s coast.

After the meal, I took a slow walk along the quay, watching the last light reflect off the water and chatting briefly with a local fisherman mending his nets. The charm of Killala is in its simplicity: great food, friendly faces, and scenic views. It’s the kind of place where you’ll want to linger a little longer and maybe return the next day just to enjoy it all again.

8. Kayak on Lough Mask or Lough Corrib

Paddling across Lough Corrib or Lough Mask is a peaceful yet adventurous way to take in County Mayo’s natural beauty. These vast freshwater lakes are surrounded by forests, hills, and small islands, making them ideal for exploring by kayak. I rented gear from Lough Corrib Adventures, and their team helped map out a relaxed route along the shoreline that included a stop near a ruined castle—quiet, scenic, and easy to follow.

The calm waters made it perfect even for beginners, and the occasional splash from a curious trout kept things lively. Being out there, surrounded by wide skies and clear water, is an unforgettable experience. Whether you’re looking to disconnect or just enjoy a fun day outdoors, kayaking here is one of the best ways to immerse yourself in Mayo’s wild side.

9. Attend the Ballina Salmon Festival

The Ballina Salmon Festival brings the riverside town of Ballina to life every July, celebrating its deep connection to the River Moy. This week-long event includes parades, live music, heritage days, and a strong focus on local food—especially salmon, of course. The whole town joins in, and it’s easy to feel like part of the community.

When I attended, the fireworks over the river were a major highlight, lighting up the sky and reflecting off the water. Even simple things like tasting fresh-grilled salmon or chatting with vendors added to the fun.

Whether you go for the family-friendly activities or the night events, it’s a festive, energetic experience. If you’re in County Mayo from July 12th to 20th, this is one of the best ways to get a feel for local culture and community spirit.

10. Explore the Mayo Dark Sky Park

For a truly cosmic experience, make your way to Mayo Dark Sky Park within Ballycroy National Park and the Nephin Beg Mountains. This International Dark Sky Park is one of the best places in Europe to witness the night sky without light pollution. On clear nights, you can spot the Milky Way, planets, and distant galaxies.

I joined one of the park’s guided night walks and was amazed by how clearly the constellations came into view. The guides do a great job explaining the stars and sharing myths behind them. Even without a tour, the silence and clarity here are unforgettable.

There’s also a visitor center in Ballycroy offering astronomy events throughout the year. If you’re looking to trade busy itineraries for something peaceful and awe-inspiring, this park offers a one-of-a-kind connection to the universe.

11. Relax at the Thermal Spa in Mulranny

If you’re craving downtime after a few active days, head to the thermal spa at Mulranny Park Hotel overlooking Clew Bay. This seaweed-infused spa uses warm Atlantic water in its treatments, helping you unwind while surrounded by the calm scenery of the Wild Atlantic Way.

I tried the outdoor vitality pool, and soaking there while gazing at the ocean felt incredibly restorative. The seaweed baths are also worth booking—they leave your skin soft and your mind clearer. The spa’s serene design blends well with the natural environment, making it feel more like an escape than just a treatment.

Whether you’re traveling solo or with friends, it’s a great way to slow down. This is one of the most relaxing experiences in County Mayo and a perfect way to balance out the hiking, biking, and sightseeing.

12. Visit the National Museum of Ireland – Country Life

Located in Turlough Park just outside Castlebar, the National Museum of Ireland – Country Life offers a compelling look into rural Irish life from the 1850s to the 1950s. The exhibits are full of traditional tools, clothing, and handmade crafts that showcase the resourcefulness of Irish communities before modern conveniences.

Wandering through the museum, I was fascinated by the displays of turf-cutting equipment and handmade wickerwork. The layout is spacious and interactive, with great visuals for all ages. The grounds outside are just as inviting, with forest walks and a riverside setting perfect for a picnic or quiet break.

Admission is free, and the on-site café makes it an easy half-day trip. If you want to understand everyday life in old Ireland, this museum does a great job bringing those stories to life.
