March 13, 2026, Boards through the bog!

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.

The Claggan Mountain Coastal Trail also offers a gentle boardwalk route with scenic bog and coastal views.

Can I bring my dog on the hiking trails in Wild Nephin National Park?

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.

What is the best time of year to visit Wild Nephin National Park for hiking?

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.

Are there any challenging hikes for experienced hillwalkers?

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.

Is public transport available to Wild Nephin National Park, or do I need a car?

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.

Where can I park when visiting Wild Nephin National Park for a hike?

Designated parking areas are available at key access points to the park's trails.

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.

Are there any places to explore near the hiking trails?

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.
