- Slieve League Cliffs Coastal Walk: A breathtaking moderate to challenging clifftop trail (around 8–10 km return from Bunglass viewpoint) along Europe’s highest sea cliffs (601 metres), towering dramatically over the Atlantic. The path offers jaw-dropping views of swirling ocean, sea stacks, and distant Sligo mountains; far less crowded than the Cliffs of Moher, it’s a raw, windswept highlight in the Donegal Gaeltacht with opportunities to spot puffins and peregrine falcons.
- Errigal Mountain Summit Trail: A strenuous but iconic ascent (about 5 km return, 3–4 hours) to the 751-metre quartzite peak of Errigal, Donegal’s highest and most distinctive mountain. Starting from the roadside car park near Dunlewey, the steep scree-covered path rewards with panoramic 360-degree views over the Poisoned Glen, Derryveagh Mountains, and Atlantic coastline – a must for its striking conical shape and sense of achievement.
- Horn Head Cliff Loop: A spectacular moderate circular drive-and-walk route (around 8–12 km loop) on the rugged Horn Head peninsula near Dunfanaghy. The trail traces sheer cliffs, blowholes, and sea arches with stunning vistas across Tory Island, Sheephaven Bay, and the Rosguill Peninsula; rich in seabirds and wildflowers, it’s a classic Donegal coastal experience blending dramatic drops with tranquil beaches.
- Malin Head Coastal Walk (Hell’s Hole to Banba’s Crown): An exhilarating moderate out-and-back or loop (up to 10 km) along Ireland’s most northerly point on the Inishowen Peninsula. The path winds past crashing waves, the dramatic Hell’s Hole chasm, sea stacks, and WWII lookouts, ending at Banba’s Crown with sweeping views over the Atlantic and distant Scottish islands; wild, exposed, and steeped in Star Wars filming history.
- Glenevin Waterfall and Valley Trail: A gentle, family-friendly riverside walk (around 2–4 km return) in the scenic Glenevin Valley near Clonmany. The well-maintained path follows a sparkling stream through lush woodland and meadows to a picturesque 10-metre waterfall with a natural pool; peaceful and enchanting, it’s ideal for a relaxed outing with picnic spots and a sense of hidden Donegal tranquillity.
