UPDATE - the wooden walkway was damaged by fire in 2025. It is unclear if it has been rebuilt completely yet. Approach with care. An excellent wooden walkway through the marshland, and a haven for wildlife lovers.

The start/end of the Claggan Mountain trail in the Ballycroy Mountains. It's a delightful walk though Atlantic blanket bog - which is much nicer than it sounds. UPDATE - the coastal path through the marsh has been damaged by fire, so it's closed for the time being. It is possible to pass but be warned the wooden bridge is not complete throughout.

The Brogan Carroll Bothy is a simple, one room stone cottage that's an ideal shelter for hikers exploring the Nephin Beg range. The building was renovated by Mayo County Council and An Taisce with funds from two Irish-American donors: John Brogan and Barry Carroll.

There is a nice series of rocky steps here for some firm footing under your feet. The views out over the surrounding hills and forest are also very pleasant.

Wild Nephin National Park offers a diverse range of hiking experiences with over 30 routes. These include 9 easy trails, 21 moderate paths, and 2 more challenging routes, catering to various fitness levels and preferences.
The park features a wide variety of terrain, from the dramatic Nephin Beg mountain range to vast expanses of Atlantic blanket bog, including the internationally important Owenduff Bog. You'll find coastal views, ancient forest remnants, and trails that traverse old cattle roads, firebreaks, and riverbanks. Some sections, particularly in the Letterkeen Loop areas, can remain boggy year-round, so waterproof footwear is highly recommended.
Yes, the park has several easy trails suitable for families. The Colorful Insect Hotels – Mayo's Whaling Past Exhibition loop from Ballycroy is an accessible 2.5 km route, perfect for an introduction to the park. The Tóchar Daithí Bán Trail, starting at the Ballycroy Visitor Centre, is another accessible 2 km loop with boardwalk sections and panoramic views. The Claggan Mountain Coastal Trail also offers a gentle boardwalk route with scenic bog and coastal views.
Wild Nephin National Park is generally dog-friendly, but it's crucial to keep dogs on a lead at all times. This is especially important due to the presence of sensitive wildlife, ground-nesting birds, and livestock grazing in certain areas. Always check local signage for any specific restrictions on individual trails.
Yes, many of the trails in Wild Nephin National Park are circular. For example, the Letterkeen Loop from Brogan Carroll Bothy offers a moderate 10 km circular path. Another option is the Letterkeen Loop Trailhead Parking – Mullach na Buaile Hut loop, which is an 11.1 km circular route through open landscapes and woodlands.
Wild Nephin National Park is rich in natural beauty and unique features. You can explore the Maumaratta Stream Triangular Metal Bridge, discover the Tóchar Daithí Bán Orchid Meadow, or visit the Brogan Carroll Bothy. The park also offers stunning coastal views, particularly along the Claggan Mountain Coastal Trail, where you can see across to Achill Island and Bellacragher Bay.
The park is accessible year-round, but the best time to visit for hiking is typically during the drier months, from late spring to early autumn (May to September). During this period, the weather is generally milder, and the trails are less boggy. However, the park's unique status as Ireland's first International Dark Sky Park makes clear nights, especially in autumn and winter, a spectacular time for stargazing.
Yes, for very experienced hikers, the Bangor Trail offers a significant challenge. This 40 km route, which can take up to 12 hours or be done over two days with wild camping, traverses wet, exposed, and rough ground through the Nephin Beg Mountains. It is considered one of Ireland's toughest day hikes, and hikers must register in advance for such advanced trails.
The area is highly rated by the komoot community, with an average score of 4.5 stars from over 130 reviews. Hikers frequently praise the park's untouched wilderness, the diverse landscapes, and the sense of solitude. Many appreciate the well-marked trails and the opportunity to experience one of Europe's largest expanses of Atlantic blanket bog.
Public transport options directly into the heart of Wild Nephin National Park are limited. While there might be bus services to nearby towns, accessing the trailheads typically requires a car. It is advisable to check local transport schedules and plan for private transport or taxi services to reach specific starting points within the park.
Designated parking areas are available at key access points to the park's trails. For instance, there is parking at the Ballycroy Visitor Centre, which serves as a starting point for trails like the Tóchar Daithí Bán. The Letterkeen Loop walks also have trailhead parking, such as the Letterkeen Loop Trailhead Parking – Brogan Carroll Bothy loop from Srahmore ED. Always use official parking facilities and avoid obstructing local roads or private access.
Beyond the trails, you can visit the Ballycroy Visitor Centre for more information about the park's ecology and history. The park itself is a designated International Dark Sky Park, offering exceptional stargazing opportunities on clear nights. You can also find the Wild Nephin National Park forest areas, which provide a different natural environment to explore.
