Overview
Lough Gartan (also known as Gartan Lough or Lough Beagh South) is a freshwater lake tucked into the rolling hills of north County Donegal, just inside the eastern fringe of Glenveagh National Park. The lake lies roughly 30 km west of Letterkenny and is framed by dense woodlands, open fields and the distant Derryveagh Mountains. Its calm, reflective waters make it a favourite spot for walkers, birdwatchers and anglers alike.
History & Background
The name Gartan derives from the nearby village of Gartan, a place steeped in early‑Christian lore. According to tradition, Saint Columba (St Colmcille) was born on the shores of the lake in AD 521, a fact commemorated by a large stone cross at the start of a footpath that leads into Glenveagh National Park. The lake forms part of the Leannan River Special Area of Conservation, supporting a modest but important population of Arctic char and a range of native aquatic flora.
What to See & Do
Walking and Hiking
Lough Gartan is a hub for marked trails of varying length and difficulty. Three way‑marked loops start from the car park beside Wilkins Bar in Church Hill:
| Trail | Length | Difficulty | Highlights |
|---|---|---|---|
| Red – Gartan Estate Walk | 5 km | Easy | Lakeside views, brief passage by the Gartan Outdoor Centre |
| Blue – The Quartet Walk | 14.5 km | Moderate‑to‑hard | Full perimeter of the lough on quiet minor roads, panoramic hilltops |
| Orange – Linear Route | 7 km (round‑trip) | Easy | Leads to St Colmcille’s Birthplace; continuation to Lough Inshagh Trail (8 km) to Glenveagh Castle |
Longer treks listed on Outdooractive include the 19.7 km “Scenic hike from Church Hill via An Cnoc Fada” (difficult) and the 12.2 km “Scenic hike from Gartan ED via Lough Inshagh” (difficult). These routes weave through ancient forests, open glens and ridge‑top viewpoints that overlook both Lough Gartan and the neighbouring valleys.
Fishing
Lough Gartan lies on the River Lennon fishery, which also includes Lough Fern. The lake produces occasional salmon and holds a resident population of small brown trout (¼–½ lb).
- Salmon & Sea Trout season: 1 January – 30 September (inclusive).
- Brown Trout season: 15 February – 30 September (inclusive).
- Permits: No permit is required for fishing upstream of the Ramelton stretch; anglers can fish from the shore or a small boat.
Local anglers recommend flies such as the Willie Gunn tube, Waddington, Badger, Hairy Mary and various shrimp patterns. The lake’s clear waters also make it a good spot for fly‑casting practice.
Water‑Based Activities
The Gartan Outdoor Education and Training Centre sits on the lake’s western shore. Its facilities include a slipway, a wooden‑boathouse and equipment stores for kayaking, canoeing and small‑boat sailing. The centre also runs archery, climbing and adventure courses, making the lake a lively base for active families and school groups.
Historical Walk & Local Lore
The short walk from Wilkins Bar to the lake is steeped in local story. Wilkins Bar itself is a listed building dating back to 1833 and has been run by the same family for seven generations. Adjacent to the bar is the former post‑office (operational 1899‑1955) and a small historic hotel.
A short detour leads to the Church of Ireland in Churchill, built in 1819 and restored in 1895. Its east window and side aisle were funded by Mrs Cornelia Adair of Glenveagh Castle; the stained‑glass panels depict the Baptism of St Columba, his landing in Iona and his death.
Across the lake, a row of stepping stones known as St Columba’s steps links Bell Point to the southern shore where the Glebe Gallery stands. Local legend says Columba crossed here on one boot while fleeing enemies; a curse is said to fall on anyone who puts on the second boot later.
Cultural Highlights
- St Colmcille’s Birthplace – a modest stone structure marking the saint’s traditional birthplace, reachable via the orange trail.
- Glebe House & Gallery – the former home of artist Derek Hill, perched on rising ground beside the lake. The house and its gardens are free to visit and showcase a mix of contemporary art, Japanese and Islamic pieces, plus a striking collection of 20th‑century works.
- Colmcille Heritage Centre – located on the Gartan Estate, this interpretive exhibition delves into the life of the patron saint of Irish monasticism.
Wildlife and Natural History
Anglers may try their luck for Arctic char, a cold‑water species that thrives in the lake’s clear depths. Birdwatchers will spot a variety of waterfowl and woodland species, especially during the spring migration when the surrounding meadows burst into colour. In autumn the forested slopes display vivid reds and golds, while winter offers the chance to see resident raptors and the occasional otter.
Events & Seasonal Highlights
- St Columba’s Feast Day – 9 June – local communities often hold a modest pilgrimage along the historic trail, with a short service at the stone cross.
- Spring wildflower walks – the lakeside meadows are carpeted with bluebells, primroses and wood anemones, making the Red loop especially popular.
- Autumn colour drives – the surrounding woodlands turn amber, providing excellent photography opportunities.
Practical Information
Lough Gartan is freely accessible and there is no admission charge. The main entry point is a small car park beside Wilkins Bar on the R251; parking is free, accommodates around 30 vehicles and includes benches and a picnic area. The car‑park surface is level, making it suitable for wheelchair users, though the longer trails involve uneven ground, steep ascents and occasional stream crossings.
Getting there – From Letterkenny follow the R251 westward for about 30 km; the turn‑off for Church Hill is clearly marked. A Google Maps link for the coordinates is available here: Lough Gartan on Google Maps.
Facilities – In addition to the car park, visitors will find public benches, a small play area in nearby Churchill (5‑minute drive), and a café at the Glebe Gallery. The Gartan Outdoor Centre provides changing rooms, showers and Wi‑Fi for day‑trippers, and offers hostel‑style rooms and ensuite apartments for overnight stays.
Seasonality – The lake and its surrounding trails are open year‑round. The spring and summer months bring a carpet of wildflowers, while autumn colours accentuate the forested slopes. Winter walks remain rewarding for those seeking solitude and the chance to spot resident wildlife.
Accessibility – While the main car‑park route is level, many of the longer trails involve uneven ground, steep ascents and occasional stream crossings. Hikers should assess each route’s difficulty before setting out.
Nearby towns – Donegal’s vibrant town of Letterkenny lies a short 15‑minute drive away, offering additional dining, shopping and accommodation options. For overnight stays directly on the lake, the Gartan Outdoor Education and Training Centre provides both hostel‑style rooms and ensuite apartments with lake views.
Enjoy the blend of natural beauty, gentle adventure and cultural depth that makes Lough Gartan a standout destination in Donegal’s north‑west landscape.
