Achill Sound is a practical starting point for two different routes: the Atlantic Drive begins here, and a 14 km section of the Great Western Greenway runs from here to Mulranny. Planning can therefore take account of both the road route and a bridge crossing, as well as a Greenway trail, a regular 5 km event and the waterside scenery. These topics can be considered separately rather than treated as one single day-trip itinerary.
Atlantic Drive and Greenway: two different routes
The Atlantic Drive starts in Achill Sound and follows the R319 over the Michael Davitt Bridge. Visitors can park along the route and explore the cliffs on foot. Both the road route and possible stops are practical points of reference when exploring the Atlantic Drive.
The waters also give the route its own geographical context: along the Atlantic Drive, you can see tidal waters fed by Blacksod Bay and Achill Sound, which flow into Bellacragher Bay. These named bays describe the location of these waterways; the cliffs can be explored on foot along the route.
The 14 km section of the Great Western Greenway from Achill Sound to Mulranny is relatively flat. Calm sea lies to the left, with mountains on both sides. The route length and scenery are two practical features to consider when planning. By contrast, the Atlantic Drive is defined by the R319, the bridge crossing and the opportunity to park along the way and explore the cliffs on foot.
Parkrun and festival dates
The Achill Greenway parkrun takes place every Saturday at 9:30 am. The 5 km course is intended for running, jogging or walking and starts at the new Greenway extension in Achill Sound. It runs from Achill Sound towards Saula and back along paved paths. This means the Saturday 5 km event can be distinguished by its occasion and distance from the 14 km Greenway section. Check the event details before your visit, as recurring information may change.
The Island Life Festival also has a cultural connection to Achill Sound, though its dates and programme vary each year. The 2026 edition took place on Achill Island and the Curraun Peninsula, ending with an Easter parade in Achill Sound. If you want to plan your trip around the festival, check the dates for the relevant year rather than assuming they are the same as for the 2026 edition.
More cultural and nature topics in County Mayo
County Mayo as a wider destination offers other distinct experiences. The National Museum of Ireland at Turlough Park presents Ireland’s rural past through objects, rare archival photographs and films. Workshops, talks and guided tours are part of the programme throughout the year. A daily Mayo Local Link service, route 454, connects the museum with Castlebar and Ballina.
Turlough Park also has gardens with a diverse range of birdlife, flora and fauna, and is designated a Green Heritage site. Knock Shrine in County Mayo offers a different historical focus, presenting the 1879 Apparition of Knock and the site’s development into an international pilgrimage destination. These regional topics complement the route and event information for Achill Sound without treating them as part of the town itself.
