Overview
Lough Tay (Irish: Loch Té) is a small, striking lake tucked in the heart of the Wicklow Mountains. Its dark, almost black surface and a strip of white sand on the northern shore give the impression of a freshly poured pint of Guinness – a visual that has earned it the affectionate nickname Guinness Lake. The lake is framed by the sheer east‑facing granite cliffs of Luggala and lies between Djouce Mountain and the Luggala ridge. While the water and surrounding shoreline belong to the private Guinness Estate, the surrounding road network provides several safe, publicly accessible viewpoints.
History & Naming
The name Lough Tay likely derives from the Proto‑Indo‑European root teh₂ meaning “to melt, dissolve, flow”. Early records from the 1650s list the lake as “Logh Tea”, long before tea was common in Ireland. The more colourful nickname comes from the former owners – the Guinness family – who imported white sand to line a beach on the lake’s northern edge, deliberately creating the visual of a Guinness pint. The estate was originally purchased by Ernest Guinness in 1937 as a wedding present for his daughter and has remained in the Guinness family trust ever since.
Film & Culture
Lough Tay’s dramatic scenery has attracted filmmakers for decades. It featured in John Boorman’s cult classics Zardoz (1974) and Excalibur (1981), and more recently served as the backdrop for the Netflix film Irish Wish (2024). The TV series Vikings also used the lake to represent the fictional village of Kattegat. Beyond the screen, the lake is linked to philosopher Bertrand Russell, who recalled a youthful visit that left a lasting impression, and to the Guinness family’s own heritage – an ornamental Temple and three family graves, including that of Tara Browne, sit on its shore.
What to See & Do
Viewpoints
The most convenient way to experience Lough Tay is from one of the car‑parks along the R759 (Sally Gap Drive). Each offers a slightly different angle of the lake and surrounding cliffs:
- Viewpoint A – Ballinastoe Woods car‑park – Across the road from the woods, this spot provides a clear line of sight over the lake. The drop is sheer, so stay well back from the edge.
- Viewpoint B – Lough Tay car‑park – This is the most popular stop; the parking area sits directly above the lake and is also the trailhead for the Djouce ascent.
- Viewpoint C – J.B. Malone car‑park – Near the memorial stone on the Wicklow Way, this location offers a panoramic view and easy access to the first board‑walked section of the Djouce summit path.
- Viewpoint D – Upper viewing point – Positioned further up the road, this spot requires no crossing of private land and delivers an unobstructed vista of the lake’s dark water against the limestone cliffs.
Walking Trails
Several marked routes let you explore the area on foot:
- Lough Tay to Lough Dan (easy, ~8 km, 1.5 h) – Starts at the kissing gate opposite Ballinastoe Woods. The trail follows a low road, crosses two small bridges, and then continues along an old stone wall to Lough Dan.
- Djouce Mountain (moderate, 6.5 km, 2‑3 h) – Begins at the Lough Tay car‑park and climbs the popular Djouce summit, offering sweeping views of the lake midway through the hike.
- Luggala Loop (difficult, 2.5‑3 h) – A steep, demanding climb from the same starting point but heading right toward the Luggala ridge. The summit provides one of the most dramatic perspectives of the lake, but the cliff edge is sheer – caution is essential.
- Guinness Lake Circuit (family‑friendly, short loop) – A gentle perimeter walk that circles the lake’s edge, ideal for casual strolls and photography.
Photography & Picnics
The contrast between the inky water and the white sand, set against the emerald hills, makes Lough Tay a photographer’s dream from sunrise to sunset. While swimming is prohibited, the designated picnic spots near the car‑parks allow you to enjoy a quiet meal with the lake as a backdrop.
Practical Information
Getting There
Lough Tay lies roughly an hour’s drive south of Dublin. The most straightforward route is via the R115 to the Sally Gap, then onto the R759. For those without a car, regular Dublin‑to‑Glendalough buses stop at Roundwood; from there it is a steep 1.5‑hour walk (no formal path) to the nearest viewpoint. Guided day‑trips from Dublin are also available and include transport, commentary, and optional stops at nearby attractions such as Powerscourt Waterfall and Glendalough.
Parking & Access
Three main car‑parks (Ballinastoe Woods, Lough Tay, J.B. Malone) are free of charge and operate on a first‑come, first‑served basis. Parking can fill quickly during peak summer weekends, especially at Viewpoint B. All car‑parks are on public road; however, the lake itself remains private property, and visitors must stay on the designated viewing areas and marked trails.
Fees & Restrictions
There is no admission fee to view Lough Tay from the public car‑parks. The lake and its immediate shoreline are off‑limits to the public, and any attempt to cross onto the private estate may result in a trespass warning.
Safety Notes
Several viewpoints have sheer drops that are not fenced. Keep children and pets well back from the edge, and stay on the marked paths. The terrain on the Luggala Loop is steep and rocky; appropriate footwear is advisable.
Nearby Attractions
The Sally Gap Drive links Lough Tay to a host of Wicklow highlights: Glenmacnass Waterfall (25 min), Powerscourt Waterfall (20 min), Victor’s Way (30 min), Lough Ouler, and the historic monastic site of Glendalough. Combining a visit to Lough Tay with any of these sites makes for a full day of scenic exploration.
