Slí Chonamara

Slí Chonamara is an easy point-to-point walk across the coast of south Connemara, running 33.1 km / 20.6 mi from Cois Trá in An Spidéal to the R372 near Ros an Mhíl. With just 195 m / 640 ft of climbing and a highest point of 62 m / 205 ft, it is a long but generally gentle day on minor roads and coastal lanes rather than a mountain outing. Most walkers will want to allow about 7 hours, with extra time for stops along Galway Bay and the small harbours and inlets along the way.

The route

From An Spidéal the trail heads west through the Gaeltacht landscape of south Connemara, staying close to the shore for much of the day before turning toward Ros an Mhíl. The route undulates only lightly, with 204 m / 669 ft of descent over the full walk, and its one named rise, Cnoc Ros an Mhíl, comes late in the day at around 32.3 km from the start. The low elevation means the character of the walk comes more from sea views, headlands, beaches and changing light over the bay than from sustained climbing.

Getting there

The start at An Spidéal is on the R336, the main road running west from Galway City along this stretch of coast. Bus Éireann route 424 serves both An Spidéal and Ros an Mhíl, which makes the linear walk practical without needing two cars. An Spidéal also has beachside parking at Cois Trá and nearby village facilities, so it works well as the starting point before returning by bus or arranging a lift from the finish.

Landscape and highlights

This is a coastal walk through an Irish-speaking part of Connemara where the road, shoreline and settlements sit between Galway Bay to the south and rougher bog and granite country inland. Around An Spidéal the coast includes village beaches and a promenade, while farther west the route passes a sequence of small coves, piers and open views toward the bay. The finish near Ros an Mhíl brings a stronger working-harbour character.

Nature and local character

Even on an easy road walk, the setting is distinctly Atlantic. West Galway’s coast is shaped by wind, salt air and low-lying coastal habitats, and machair is one of the notable habitat types found along Ireland’s western seaboard. The wider area also lies within an important coastal bird landscape, so walkers may notice waders, seabirds and other water-associated species along the shore, especially outside the busiest parts of the villages.

Terrain and preparation

Because the route is easy rather than rugged, the main challenge is its length. Good walking shoes are still useful, as the day is long and exposed to Atlantic weather, and waterproof layers can matter more here than steep-hill fitness. Food, water and transport planning are worth sorting in advance, especially if walking the full distance in one go. With such modest gradients, this is a route for steady forward progress and frequent pauses to enjoy the coast rather than for technical hiking.
