Wild Nephin Walking Trails

Walking Trails Distance Grade

Hill Walking

The three Letterkeen Loop trails above are waymarked and possible without a map and compass. The Bangor Trail is for very experienced hikers only. Hiking boots and correct rainwear are essential as these trails can become very wet underfoot. Any walker or camper undertaking one of the advanced trails must register in advance by clicking the button below.

The Bothy at Letterkeen

Explore the wild and remote areas from Brogan Carroll Bothy at Letterkeen Woods. The bothy is a dry and secure shelter to overnight on the long distance Bangor Trail and Western Way and acts as a trailhead for waymarked hiking loops of 2.5km, 5km, 10km and 12km.

Access to Letterkeen Loops

  • ranging from 2.5 km–12 km

The road to access the Letterkeen Loop walks is situated 1km out of Newport on the Mulranny side.

Hiking Safety Advice


Consult maps of the area beforehand and plan in advance


Hiking is only recommended for those with suitable outdoor clothing and equipment.


Do not venture into the hills alone.


Know your limits and those of your friends walking with you.


Inform a competent person of your walking trip and estimated time of return.


Take waste away with you. This is essential.


Leave wild flowers for everyone to enjoy. Photograph or sketch them instead of picking them.


Dogs are welcome but must be kept on a leash at all times.


Respect the National Park.


To learn more about wild camping in the park, read our Camping Code.


Be aware of ticks and their potential transmission of Lyme disease. Always check for ticks at the end of a day’s hiking.

Ticks & Biting Insects

Ireland is generally a very safe place as regards wildlife. There are no longer any large predators like bears, wolves, or large cats, but Ireland is home to smaller creatures that may prove troublesome. In Wild Nephin National Park visitors may encounter swarms of midges (small biting flies) on warm and humid days, and walkers venturing off tracks may be bitten by ticks. All walkers should be aware that ticks can, in rare cases, carry Lyme disease. Learn more about ticks and biting insects in our guide below.

Art Commission

Susan Mannion

The National Parks and Wildlife Service (NPWS) at the Department of Housing, Local Government and Heritage officially launched ‘Under Darkening Skies’ a public art commission by the visual artist Susan Mannion at the Ballycroy Visitor Centre at Wild Nephin National Park in June 2022. The artwork was commissioned by the Office of Public Works (OPW) under the Percent for Art Scheme, in collaboration with the NPWS and Mayo County Council Arts Service, to mark the tenth anniversary of the Ballycroy Visitor Centre.

The two-stage open competition which saw Susan Mannion’s proposal selected was coordinated by Mayo County Council’s Arts Service in partnership with the OPW. Susan is a visual artist based in Boyle specialising in copper enamel work, a technique that has been used since the 13th century BC.

The artwork was created from enamelled steel and is comprised of seven panels that when combined measures 7 metres in width and 4 metres in height. The steel panels were coated in base coats of black and then white enamel and fired to create a blank canvas onto which colour enamel powder was sifted. Twelve different colours of enamel were applied and then the panels were fired at 810 degrees in huge kilns. ‘Under Darkening Skies’ can be seen on the exterior wall on the Ballycroy Visitor Centre.

Mayo Dark Sky Park

Wild Nephin National Park is Ireland’s Big Sky Country and the acclaimed Irish poet WB Yeats illustrates the awesomeness of these west of Ireland skies in “He Wishes for the Cloths of Heaven”. Yeats describes the “heavens’ embroidered cloths, enwrought with golden and silver light, the blue and the dim and the dark cloths of night and light and the half-light”.
Indeed we do not lose these big skies at night as half the National Park is after dark. Learn more about exploring the skies above the National Park in our stargazing section below.


Wild Nephin National Park showcases some of the darkest, most pristine night skies in the world and is officially certified as the Gold Tier International Mayo Dark Sky Park. Take a look at the resources below if you’re interested in getting started or developing your stargazing knowledge.

Observatory & Planetarium

Following a successful application for funding to the Rural Regeneration and Development Fund in 2019, the NPWS in partnership with Fáilte Ireland and Mayo County Council have plans for the design of two new visitor experiences in the Mayo Dark Sky Park (Wild Nephin National Park).

Research and scientific and environmental assessments have been undertaken to identify suitable locations for a Planetarium and Multimedia Space and Observatory to be located in Mayo Dark Sky Park. Expert reports were commissioned on Astrotourism Suitability, Environmental Impact, Rural Tourism Development, Community Employment and Economic Impact with recommendations for the most suitable sites.
Ballycroy Visitor Centre has been identified as the site for the Planetarium and Multi Media Space, while the optimal site for the Observatory is in the Mayo Dark Sky Park at Letterkeen in Wild Nephin National Park. Find out more by following the link below.
