Keem Bay is a horseshoe of white sand at the far western tip of Achill Island in County Mayo, hemmed in by steep green cliffs on three sides and open Atlantic on the fourth. For a lot of visitors, Keem Bay Achill Island is the whole reason to point the car toward Mayo. If you only make one stop on Achill, make it this one.

The beach earned a Blue Flag for its water quality, and the drive in is half the draw. The road corkscrews up and over the headland with the bay dropping away below you, and there’s a small parking lot at the top where you’ll want to pull over just to take it in.

It also got a real bump in fame when it showed up in The Banshees of Inisherin, so plenty of visitors now arrive already knowing the view. It’s touristy in high summer, and it’s still worth it.

Below I’ll cover the history and the film connection, the cliff hike above the beach, the other things worth doing on Achill, where to stay nearby, and the easiest tours to get you here if you’d rather not drive that road yourself.

Quick Answer:

Keem Bay is a Blue Flag beach at the western tip of Achill Island in County Mayo, about a 90-minute drive from Westport. A narrow cliff road leads down to sheltered, swimmable water and a small car park that fills fast in summer. Arrive before 11am and give it a half-day.

The History and Film Fame of Keem Bay

Keem Bay looks like it has always been a beach for swimming and photos, but for a few decades it was a working fishery. The remains of the old lookout hut are still up on the hillside, and once you know what happened here, that empty little building on the cliff makes a lot more sense.

Basking Sharks at Keem Bay

A basking shark breaks the surface off Achill, a common sight in early summer.

Every spring, basking sharks move into the waters off Achill to feed on plankton. They’re the second-largest fish in the world, they can grow past 25 feet, and they cruise near the surface with their mouths wide open. Harmless to people, but massive.

From the late 1940s through the 1970s, Keem Bay was the center of a commercial shark fishery. Fishermen strung nets across the mouth of the bay and hunted the sharks for the oil in their livers, which sold well at the time for lamps, cosmetics, and machine oil.

In the busiest years the catch ran into the hundreds of sharks a season, and eventually the numbers dropped off and the fishery wound down. The hut on the headland was the spotter’s post, where a lookout watched for fins and signaled the boats below.

The good news is the sharks came back. Achill is now one of the better places in Ireland to see basking sharks, and late May into June is your best window. If you’re up on the cliff path on a calm day, keep an eye on the water below.

The Banshees of Inisherin Connection

Keem’s green headland, the stretch you’ll recognise from Banshees of Inisherin.

Keem Bay got a whole new wave of visitors after The Banshees of Inisherin came out in 2022. Martin McDonagh shot large parts of the film on Achill, with Colin Farrell and Brendan Gleeson, and the fictional island of Inisherin is really a mix of Achill and Inishmore.

That green headland with the cottage and the sea behind it, the one that shows up all over the film, is Achill. The movie racked up nine Oscar nominations, and a lot of people who watched it clocked the scenery before they ever knew the name of the place.

So plenty of visitors now arrive already recognizing the view from the screen. You don’t need to be a fan of the film to enjoy the bay, but if you have seen it, standing above Keem is a fun payoff. It really does look exactly like it does on screen.

The Keem Bay Hike

coastal cliff walking path above the Atlantic on Achill
The clifftop path above Keem is the walk to do once you’re off the sand.

The best thing to do at Keem, once you’ve been in the water or had enough of the sand, is walk up the cliffs on the western side of the bay. A path climbs from the beach up toward that old lookout hut, and the higher you get, the better the view back down over the horseshoe of sand.

The first stretch is a steady climb, and it’s steep enough to get your legs going, but nothing technical. Take it slow, stop for photos, and give it an hour or so if you just want to reach the headland and come back.

Up to Moyteoge Head and Beyond

The old signal hut on Moyteoge Head, right above the bay.

The headland on the far side of the bay is Moyteoge Head, and the old signal hut sits right up there on the edge. From that point you look straight down onto Keem below and out at the open Atlantic, and on a calm day it’s the spot to scan the water for basking shark fins.

Keen walkers can keep going west along the ridge toward Achill Head, the long finger of land that runs out to the very end of the island. That’s a proper hike over open, exposed ground with no barriers, so save it for good weather and don’t attempt it in fog or high wind.

Croaghaun and the Sea Cliffs

Croaghaun drops into some of the highest sea cliffs in Europe.

Rising behind Keem is Croaghaun, and its far side drops into some of the highest sea cliffs in Europe, over 600 meters straight down to the water. You can’t see that drop from the beach, and reaching the summit is a long, unmarked hike for experienced walkers only.

If you’re fit and the weather is clear, the climb up to Croaghaun and along the cliff edge is one of the best walks in the west of Ireland. If you’re not, the shorter loop up to the lookout hut and back gives you most of the view for a fraction of the effort.

Wear real shoes, bring a layer for the wind, and check the forecast before you commit to anything past the headland. The ground gets boggy, the edges are unfenced, and the weather on Achill can turn fast.

Other Things to Do on Achill Island

Keem is the headline, but Achill is a big island and you could easily fill two or three days here. The other stops fall into three buckets: more beaches, the drive itself, and a couple of things that are just plain unusual. Here’s what’s worth your time once you’re done at the bay.

The Deserted Village at Slievemore

On the slopes of Slievemore mountain sits a line of about 80 to 100 stone cottages, all of them roofless and empty. This is the Deserted Village, and people lived here until the 19th century before the Famine and changing farming pushed the last families out.

You can walk right among the ruins for free, and it’s an easy stop off the main road. The stone walls run in a long row along the hillside, and standing up there with the sea below you gives you a real sense of how tough life on the island once was.

The Beaches: Keel, Dugort and the Blue Flags

Keel beach and mountains on Achill Island
Keel beach runs long and flat under the island’s mountains.

Achill has five Blue Flag beaches, which is a lot for one island. Keel is the big one, a long stretch of sand backed by the village where most of the island’s food and pubs are. It’s also the spot for surfing and there’s a surf school if you want a lesson.

Over on the north side, Dugort and the Golden Strand give you calmer, quieter sand with a view across to the mainland. If Keem is packed in high summer, these are your fallback, and they’re worth a look regardless.

The Atlantic Drive

The Atlantic Drive traces the island’s southern edge, and it’s a short loop worth doing.

The Atlantic Drive is a loop around the southern edge of the island, and it’s one of the best short coastal drives in Ireland. The road hugs the cliffs with the ocean on one side, and there are pull-ins where you can stop for photos or just watch the water crash below.

Along the way you’ll pass Kildavnet Tower, a small 15th-century tower house linked to the pirate queen Grace O’Malley, right down by the water. It takes five minutes to look around and it’s a good excuse to stretch your legs.

Achillhenge and Climbing Slievemore

A ring of standing stones in an Irish field, the kind of oddity Achillhenge trades on.

Achillhenge is exactly what it sounds like: a ring of huge concrete pillars built in a field, put up over a single weekend in 2011 as a protest piece. It’s odd, it’s unofficial, and plenty of people make the short walk out to see it just because it’s there.

For something more demanding, Slievemore is the island’s second-highest peak at around 670 meters. The climb is steep and the ground is boggy, but on a clear day the view from the top runs the length of Achill and out over the bays. Save it for good weather and wear proper shoes.

Where to Stay Near Keem Bay

There’s nowhere to stay right at Keem Bay itself. It’s the far western tip of the island, just the beach, the parking lot, and the cliffs. So you’ll base yourself elsewhere on Achill and drive out, which takes about 20 minutes from the main village.

Keel is the village to book. It’s the closest cluster of accommodation to Keem, it sits on its own Blue Flag beach, and it has most of the island’s pubs and food. You can also stay near Dugort on the quieter north side or at Achill Sound by the bridge, or base yourself on the mainland in Westport and treat Achill as a long day trip. Rooms book up fast in high summer, so lock one in early. Here are three places in Keel worth your money.

Best Tours to Keem Bay and Achill Island

Achill is connected to the mainland by a bridge, so you can drive the whole way, and plenty of visitors do. But that road out to Keem is narrow and steep, and if you’d rather sit back and let someone else take the corners, a guided tour of Keem Bay Achill Island is a solid call.

Just know what you’re signing up for. Achill is remote, so organized tours tend to be long days that pair the island with the wider Mayo coast, not a quick hop out to the beach and back.

Westport is the closest town of any size, about an hour from the island, and it’s the most sensible base for a day trip. From Galway it’s closer to two hours each way, so tours from there tend to cover a big sweep of Mayo and Connemara rather than Achill on its own. Here are the tours worth booking near a Keem trip.

Croagh Patrick E-Bike and Pub Food Experience

Croagh Patrick E-Bike and Pub Food Experience

This one runs from Westport and pairs an electric bike ride out under Croagh Patrick with a stop at a local pub for food, so you get the mountain views without grinding up the hills yourself. It’s a good half-day if you’re basing near Achill and want an easy day off the driving.

Galway to Connemara, Cong and Kylemore Abbey Day Tour

Galway to Connemara, Cong and Kylemore Abbey Day Tour

If you’re based in Galway rather than Westport, this full-day tour is the closest you’ll get to Achill’s wider region, taking in Kylemore Abbey, the village of Cong, and the Connemara coast. It won’t get you to Keem itself, but it covers the same sweep of the west that makes the drive up worth it.

👉 See what’s included on the Connemara and Kylemore Abbey Day Tour


Killary Fjord Sightseeing Cruise

Killary Fjord Sightseeing Cruise

Seeing this stretch of coast from the water is a different thing entirely, and if the Achill boats aren’t running this 1.5-hour cruise reliably gets you out on Killary Fjord, down on the Mayo and Galway border. The catamaran has an indoor saloon, so it runs even when the weather turns.

Should You Just Drive It Yourself?

The road out to Keem is narrow and steep, and driving it yourself is the freedom option.

For most visitors, yes. A car gives you the freedom to sit at Keem as long as you want, chase the good light, and detour to the Deserted Village or the Atlantic Drive on your own clock. If you don’t have your own wheels, you can compare car hire deals on Discover Cars before you go. Tours are the better pick if you don’t want to drive at all, or you want a boat and a guide who knows the water.

Plan a Bigger West of Ireland Road Trip

Keem Bay FAQs

These are the questions visitors ask most before making the drive out to Keem. Short, practical answers on swimming, parking, driving the road, and timing your trip.

Can you swim at Keem Bay?

Yes. Keem is one of the safer beaches on Achill to swim, because the cliffs on three sides shelter it from the worst of the Atlantic swell, and the water is clean enough to hold a Blue Flag. It’s cold year-round, so bring a wetsuit if you plan to stay in more than a few minutes.

Is Keem Bay free to visit?

It is. There’s no entry fee for the beach and no charge for the parking lot at the top of the headland. Just be aware the lot is small and fills up fast on a sunny day in July or August, so get there early if you want a spot.

Can you drive to Keem Bay?

Yes, the road runs all the way to the beach. It’s narrow and steep, and it climbs and drops over the headland with a couple of tight bends and no barrier on the sea side. Take it slow, use the pull-ins to let oncoming cars pass, and you’ll be fine.

How long should you spend at Keem Bay?

Give it at least two hours. That’s enough to get down on the sand, have a swim, and walk part way up the cliff for the view back over the bay. If you want to hike up to the lookout hut and take your time, plan on half a day.

When is the best time to visit Keem Bay?

Late May into June is the sweet spot. The weather is settling, the crowds haven’t hit their July and August peak, and it lines up with your best shot at basking sharks off the headland. Any clear day from late spring through early autumn is worth it.

Are there facilities or a café at Keem Bay?

Barely any. There’s the beach, the parking lot, and usually a seasonal food truck or two in summer, but no shops, no proper café, and limited toilets. Stock up on food and water in Keel before you drive out, so you’re not stuck.

Where was The Banshees of Inisherin filmed on Achill?

Large parts of the film were shot around Achill, and Keem Bay’s green headland is one of the most recognizable backdrops. The fictional island of Inisherin is a mix of Achill and Inishmore, so if a view looks familiar from the screen, you’re probably standing in the right place.

In short

  • Keem Bay holds a Blue Flag for water quality and sits at the western tip of Achill Island.
  • The drive from Westport takes about 90 minutes on a narrow cliff road that overlooks the bay.
  • The parking lot fills fast in summer; arrive before 11am to get a spot.
  • Basking sharks appear in the waters off Keem from late May into June, sometimes hundreds in a season historically.
  • The beach appeared in The Banshees of Inisherin, which brought a noticeable spike in visitors.

Final Thoughts on Visiting Keem Bay

dramatic light breaking over the coast of County Mayo
Storm light over the Mayo coast, the kind of view that makes the drive worth it.

Keem Bay is the kind of beach that lives up to the photos, which is rarer than it sounds. The horseshoe of sand, the cliffs on three sides, the Atlantic out front, it really does look exactly like it does on screen, and that’s the whole reason to make the drive.

Yes, it’s touristy in July and August, and the tiny parking lot fills fast. That doesn’t take much away from it. Go on a weekday in late spring or early autumn, get there early, and you’ll get the best of the bay with a fraction of the crowd.

The move is to give it a proper half-day. Have a swim, walk up to the lookout hut for the view back down, and scan the water for a basking shark fin if you’re there in the right window.

Pair it with a night or two in Keel and a lap of the Atlantic Drive, and Achill turns into one of the best stops in the west of Ireland. If you only make one detour off the main tourist trail in Mayo, make it this one.
