Overview
Derrigimlagh Discovery Point sits on a 5 km sign‑posted loop that winds through one of Europe’s most extensive blanket bogs. Located just 4.3 km south of the colourful town of Clifden on the R341, the site is a designated Signature Discovery Point on the Wild Atlantic Way. The landscape is a mosaic of peat‑covered plains, reflective pools and wandering black‑faced sheep, but the real draw is the twin milestones of 20th‑century communication and aviation that unfolded here.
History
Marconi’s Trans‑Atlantic Wireless Station
In 1907 Guglielmo Marconi chose the flat, windswept expanse of Derrigimlagh Bog to house the world’s first permanent trans‑Atlantic radio station. The station comprised a condenser house, power plant, workshops and staff housing, employing up to 300 people at its peak. From this remote outpost the first commercial wireless telegrams crossed the Atlantic to Glace Bay, Newfoundland, ushering in a new era of instant global communication. The complex burned during the Irish War of Independence in 1922, leaving only concrete foundations and a few interpretive panels to hint at its former scale.
Alcock & Brown’s First Non‑Stop Flight
A decade later, on 15 June 1919, British aviators John Alcock and Arthur Whitten‑Brown completed the world’s first non‑stop trans‑Atlantic flight in a Vickers Vimy bomber. After 16 hours and 28 minutes aloft, they sighted the Connemara coast and attempted a landing on what they thought was a field. The bog’s soft peat swallowed the aircraft’s wheels, and the plane nose‑dived into the ground. Both men emerged uninjured, and a simple white stone beacon now marks the exact landing spot.
The two events are commemorated along the walk by interpretive shelters, historic photographs and a sculptural wing‑shaped memorial on the Errislannan Peninsula.
What to See & Do
- Marconi Loop Walk – The 5 km circuit is a gentle, mostly flat route that combines boardwalk sections with compacted gravel. It takes most visitors 1.5–2 hours at a relaxed pace.
- Interpretive Information Points – Weather‑proof shelters house panels, historic photographs and “historioscopes” that overlay past images onto the present landscape, allowing you to visualise the original Marconi buildings.
- Alcock & Brown Landing Beacon – A white stone cairn marks the crash‑landing site. From here you can glimpse the surrounding bog and, on clear days, the Twelve Bens mountain range.
- Wildlife & Landscape – The blanket bog supports a rich array of flora and fauna, from heather and sphagnum moss to wading birds that frequent the shallow pools.
- Interactive Installations – Along the trail you’ll find a tuning‑fork organ, a parabolic mirror that plays with light and sound, and crystal‑radio displays that echo the site’s wireless heritage.

The site is maintained by the Connemara Chamber of Commerce in partnership with Fáilte Ireland and Galway County Council. A downloadable fact sheet and brochure are available from the chamber’s media hub: Fact Sheet PDF and Brochure PDF.
Because the walk is open all day, you can time your visit to catch the soft golden light of late afternoon, which makes the bog’s pools mirror the sky and highlights the distant mountain silhouettes. The site is also popular with cyclists; the loop is suitable for mountain bikes, and the car‑park provides easy access for bike rentals in Clifden.
For those interested in deeper research, the project website for the proposed Derrigimlagh‑to‑Kylemore Greenway offers maps and consultation documents: derrigimlaghtokylemoregreenway.ie.
Whether you are a history enthusiast, a nature lover, or simply looking for a quiet walk off the beaten path, Derrigimlagh Discovery Point delivers a compelling blend of technology, adventure and Irish landscape that is hard to find elsewhere on the Wild Atlantic Way.
