Overview
Lough Bray consists of two glacial corrie lakes – Upper and Lower – set into the eastern face of Kippure within the Wicklow Mountains National Park. Located roughly 25 km (15 mi) south of Dublin, the lakes are visible from the Old Military Road (R115) but truly reveal themselves only to those willing to leave the tarmac. Their deep, dark waters sit in bowl-shaped basins carved out over 10,000 years ago, offering a quieter, more rugged alternative to nearby tourist hubs like Glendalough or Lough Tay. The area is best known for its unmarked hiking trails, the dramatic granite outcrop of Eagle’s Crag, and the chance to wild-swim in cold, clear mountain water.
Getting There & Parking
There is no public transport to the lakes; a car or bicycle is required. From Dublin, take the M50 south to Exit 11 (N81), follow signs toward the Wicklow Gap, and continue onto the R115. The drive takes approximately 35 minutes in light traffic.
Two main parking options serve the trailheads:
- Quarry Car Park – Located directly opposite Upper Lough Bray on the left side of the R115. It holds roughly 15 vehicles and fills quickly on weekends. Due to its isolated position, theft has been reported; walkers strongly advise leaving the car completely empty, with glove boxes and under-seat compartments open.
- Glencree Centre for Peace and Reconciliation – A safer, more secure lot with a café and toilet facilities. Parking here adds roughly 2 km of road walking to the start of the trail but eliminates the risk of vehicle break-ins.
Walking Routes
The trails around Lough Bray are not signposted. Hikers should download offline maps (such as Maps.me or AllTrails) before setting out and stick to well-worn paths. The routes vary in length and difficulty:
| Route | Distance | Elevation Gain | Typical Time | Difficulty |
|---|---|---|---|---|
| Lough Bray Upper & Lower Loop | 6.7 km (4.2 mi) | ~300 m | 2–3 h | Moderate (muddy, unmarked) |
| Lough Bray Upper Loop | 3.5 km (2.2 mi) | ~150 m | 1.5 h | Moderate |
| Kippure via Lough Bray | 9 km (5.6 mi) | ~380 m | 3–4 h | Moderate/Difficult (off-trail bog) |
Key highlights
- Eagle’s Crag – A prominent granite buttress that dominates the valley. The path zigzags up to the summit, offering clear views of both lakes, the Sugar Loaf, and the Irish Sea. The descent back down involves short scrambles over slippery boulders.
- Lough Bray House – A private 19th-century residence on the northern shore of Lower Lough Bray. Originally built as a shooting lodge for the Powerscourt Estate, it later passed to the Guinness family. The owners maintain a man-made sandy beach on the western shore, with sand hauled from Brittas Bay.
- Kippure Summit – The highest point in the historic County Dublin (750 m), marked by a TV mast. The detour requires brief off-trail navigation across boggy heather and uneven ground, but rewards walkers with a 360° panorama stretching to Dublin city and the Wicklow range.
History & Folklore
Local legend attributes the steep, gouged cliffs to Fionn MacCumhaill, who supposedly scooped up rock and soil while pursuing a wild boar. The folklore also claims the lakes are bottomless and connected to the sea. Geologically, the truth is equally striking: both lakes are classic corrie basins formed by glacial erosion during the last ice age.
The surrounding moorland contains remnants of ancient field systems and old pathways, hinting at centuries of upland habitation. Lough Bray House remains the most visible marker of the area’s aristocratic past. Though private, its position on the lakeshore is clearly visible from the trail, and the gated lane leading to it is well-marked to prevent accidental trespass.
Wild Swimming
Upper Lough Bray is a recognised spot for wild swimming. The water remains cold year-round, and the lake features steep drop-offs typical of glacial formations. There are no lifeguards, changing facilities, or designated swimming zones. If you plan to swim:
- Wear a wetsuit unless you are an experienced cold-water swimmer.
- Bring a hot-water flask, dry layers, and a waterproof change-robe.
- Never swim alone and always inform someone of your plans.
- Check weather conditions carefully; sudden drops in temperature or strong winds can make the lakeside dangerous.
Practical Tips & Safety
- Navigation – Trails are faint in places and can disappear in mist. Carry a paper map and compass as a backup to digital apps.
- Footwear – Sturdy hiking boots with good grip are essential. Gaiters are recommended after rain, as the lower lake approach and ridge paths become deeply muddy.
- Vertigo & Exposure – Sections near Eagle’s Crag involve exposed ridge walking and short scrambles. The route is not suitable for those prone to vertigo or severe anxiety about heights.
- Weather – Mountain conditions change rapidly. A waterproof jacket, windproof layer, and warm hat should always be packed, even in summer.
- Dogs – Leashed dogs are welcome on the trails. Keep them under control when passing the private grounds of Lower Lough Bray and the gatehouse near Lough Bray House.
Nearby Attractions
After completing the hike, the R115 corridor provides easy access to several other Wicklow highlights. The Sally Gap sits just a few kilometres west, offering a classic mountain driving route and starting points for longer summits like Camaderry or the rugged Camenabologue. For a change of scenery, a short drive north leads to Avondale Forest Park and the historic Powerscourt Estate. Plan your return journey with extra time for parking, as the Quarry lot rarely has spaces after midday on weekends.
