National Parks Ireland – 8 Parks Across 96,000 Hectares

National parks Ireland now encompasses eight protected areas covering approximately 96,500 hectares of mountains, bogs, lakes, woodlands, coastline and marine environments. Managed by the National Parks and Wildlife Service (NPWS) under the Department of Housing, Local Government and Heritage, the network ranges from Killarney – the oldest park, established in 1932 – to Pairc Naisiunta na Mara, Ireland’s first marine national park, designated in April 2024 and the largest in the state at roughly 28,000 hectares of land and sea. This guide covers each park, visitor numbers, conservation challenges, NPWS reform and the parks’ role in Ireland’s outdoor tourism offering.

🏔️ The Eight National Parks

Ireland’s eight national parks represent the country’s most significant protected landscapes. Seven are terrestrial parks covering approximately 68,500 hectares, while the eighth – the marine national park – adds a further 28,000 hectares of land and sea. Each is managed according to criteria and standards set by the International Union for Conservation of Nature (IUCN), with the primary purpose of conserving habitats, biodiversity and natural heritage for current and future generations. Public access is permitted under special conditions for recreation, education and cultural purposes.

Killarney National Park, County Kerry

Established in 1932 as Ireland’s first national park, Killarney covers over 10,000 hectares at the foot of the MacGillycuddy’s Reeks, Ireland’s highest mountain range. The park encompasses mountains, lakes, waterfalls and Ireland’s most extensive area of ancient native oak woodland. It is home to Ireland’s only native red deer herd and contains the Victorian-era Muckross House and Gardens, one of Ireland’s most visited heritage sites. Killarney is by far the most visited of Ireland’s national parks, with over 1.54 million people visiting in 2025 – a 10% increase on the previous year. Muckross House alone welcomed over 966,000 visitors, while Killarney House and Gardens attracted more than 367,000. In total, NPWS-managed destinations in Kerry recorded approximately 2.88 million visits in 2025.

Wicklow Mountains National Park

The largest terrestrial national park at almost 20,500 hectares, Wicklow Mountains National Park covers a vast expanse of upland blanket bog, heathland, native woodland and glacial valleys in the Dublin hinterland. Its proximity to the capital – less than an hour’s drive from the city centre – makes it the most accessible of the eight parks and one of the most heavily used. The park is home to over 1,000 species of flora and fauna. The Wicklow Way, Ireland’s oldest waymarked trail, passes through the park, and the monastic settlement at Glendalough is one of Ireland’s most visited heritage sites.

Glenveagh National Park, County Donegal

Renowned for its remoteness and wilderness character, Glenveagh covers approximately 16,000 hectares of mountains, lakes, waterfalls and woodland in the heart of Donegal. The park includes Glenveagh Castle and its gardens, set on the shores of Lough Veagh. The park is an important conservation site for golden eagles, which were reintroduced to Donegal in 2001 after an absence of nearly a century.

Connemara National Park, County Galway

Covering approximately 2,000 hectares, Connemara National Park protects a compact but diverse landscape of mountains, bogs, heaths, grasslands and native woodland in the west of Ireland. The park includes several peaks of the Twelve Bens mountain range and is home to around 500 species of flora and fauna, including the iconic Connemara pony. The Diamond Hill boardwalk trail is one of the park’s most popular attractions.

The Burren National Park, County Clare

The smallest national park at approximately 1,500 hectares, the Burren protects a unique limestone landscape that supports an extraordinary diversity of plant life. Arctic, alpine and Mediterranean species grow side by side in the pavement crevices and grassy terraces of this seemingly barren landscape. The Burren’s archaeological heritage is equally rich, with megalithic tombs, ring forts and medieval settlements scattered across the park.

Ballycroy National Park (Wild Nephin), County Mayo

Located on the western seaboard, Ballycroy covers a vast expanse of Atlantic blanket bog – one of the last remaining intact blanket bog systems in Europe. The park includes the Nephin Beg mountain range and was designated as Ireland’s first International Dark Sky Park in 2016, recognising the exceptional quality of its night skies. The park’s Wild Nephin designation reflects its wilderness character and role as a refuge for species that require large, undisturbed landscapes.

🌿 Conservation Role and Biodiversity

Ireland’s national parks are first and foremost conservation areas. They protect habitats including blanket bog, native oak and birch woodland, limestone pavement, mountain heathland, freshwater lakes and rivers, and coastal ecosystems. These habitats support species of national and international conservation importance, from Killarney’s native red deer and Lesser Horseshoe bats to the rare arctic-alpine plants of the Burren and the golden eagles reintroduced to Glenveagh.

The parks sit within a broader framework of protected areas that includes hundreds of Nature Reserves covering over 18,000 hectares, along with EU-designated Special Areas of Conservation (SACs) and Special Protection Areas (SPAs) under the Natura 2000 network. Together, these designations form Ireland’s contribution to European biodiversity protection, though Ireland’s record on habitat and species conservation has been criticised by environmental organisations and EU assessors.

Key conservation challenges within the parks include rhododendron invasion in Killarney (an invasive species that smothers native woodland), deer overpopulation in several parks, upland erosion on popular walking routes, and the ongoing threat of wildfire – Killarney National Park was ravaged by fire in 2021, causing widespread damage to habitats that had developed over centuries. Climate change presents additional long-term threats, altering habitats, fire risk and species distribution patterns.

🏛️ NPWS – Reform and Challenges

The National Parks and Wildlife Service has faced persistent criticism for underfunding, staff shortages and inadequate management capacity. A major independent review of the NPWS, completed in 2021 and led by Professor Jane Stout of Trinity College Dublin and Dr Micheal O Cinneide, former EPA director, found that the service could not meet its current biodiversity obligations, let alone plan for future challenges and legislation.

One of the review’s 24 major recommendations was the appointment of dedicated park managers for each of the six national parks. The review noted that parks were being managed by staff who also carried wide-ranging other duties, a situation it described as unsustainable given that NPWS facilities receive an estimated three million visitors per year and visitor numbers are projected to increase. The review called for management plans to be drafted for each park through extensive consultation with local communities, stakeholders and conservation staff.

The government has committed to strengthening the NPWS, and reform efforts are underway. Additional funding and staff recruitment have been announced in successive budgets. However, the pace of change has been criticised by environmental organisations who argue that Ireland’s biodiversity crisis requires urgent investment rather than incremental improvement. Ireland’s most recent Article 17 report to the EU on the status of habitats and species showed continued deterioration in many protected habitats, underlining the gap between conservation commitments and delivery on the ground.

The NPWS operates under the Department of Housing, Local Government and Heritage, and competing priorities within that department – particularly the housing crisis – have historically limited the political attention and resources available for nature conservation. Advocates have called for the NPWS to be established as an independent agency with its own board and budget, similar to models in other European countries, to give nature conservation the institutional weight and independence it requires.

Pairc Naisiunta na Mara, County Kerry

Designated in April 2024, Pairc Naisiunta na Mara (Kerry Seas National Park) is Ireland’s first marine national park and the largest in the state. Covering approximately 28,000 hectares (77,000 acres) of land and sea, the park is centred on Corca Dhuibhne and the Dingle Peninsula. It unites some of Europe’s most ecologically valuable marine and coastal sites, including the UNESCO World Heritage Site of Sceilig Mhichil, the Blasket Islands, the sand dunes at Inch Beach, the uplands of Mount Brandon (952m), the Conor Pass and the Kerry Head Shoal – a deep limestone reef designated as a Special Area of Conservation. The state acquired 1,400 acres of land near the Conor Pass and the Owenmore River catchment to enable the park’s creation. The designation represents a new direction for national park policy in Ireland, extending the concept from terrestrial landscapes to the marine environment, and a public consultation on the park’s future management was launched in early 2025.

🥾 Visitor Infrastructure and Recreation

The national parks provide free public access and a range of visitor facilities including visitor centres, car parks, waymarked trails, education programmes and interpretation services. Killarney and Glenveagh have the most developed visitor infrastructure, including heritage houses and formal gardens. Wicklow Mountains and Connemara offer extensive trail networks, while the Burren and Ballycroy provide more contemplative, lower-footfall experiences.

Killarney National Park offers the most diverse visitor experience of any Irish national park. The traditional jaunting car ride through the Gap of Dunloe, the boat trip across the lakes to Lord Brandon’s Cottage, cycling through the park’s extensive road network and walking trails ranging from lakeside strolls to challenging mountain ascents all contribute to an experience that draws visitors from around the world. The park’s ability to offer everything from gentle family outings to serious mountain walking within a single protected landscape is a significant part of its appeal.

The parks connect directly with Ireland’s broader walking trail network, with several national waymarked ways passing through or adjacent to park boundaries. The Kerry Way, one of Ireland’s most popular long-distance walks at approximately 215km, passes through Killarney National Park, while the Wicklow Way traverses the mountains of Wicklow National Park. The Burren Way connects the national park to the broader Clare walking network. Three of the terrestrial parks – Connemara, Killarney and Ballycroy – sit along or near the Wild Atlantic Way, acting as anchor attractions for touring visitors.

Failte Ireland has a strategic partnership with the NPWS aimed at enhancing and promoting tourism at the national parks and nature reserves in a sustainable way. Tourism Infrastructure Masterplans (TIMPs) have been developed to guide investment in visitor facilities, balancing the need for improved infrastructure with the conservation purpose of the parks. This partnership recognises the parks as critical elements of Ireland’s tourism offering and channels Failte Ireland capital funding towards improving visitor experience infrastructure.

📈 Growing Visitor Pressure

The post-pandemic surge in outdoor recreation has created new pressures on park infrastructure. Trail surfaces on popular routes have degraded under heavy use, car parks overflow during peak periods, and the balance between encouraging public access and protecting sensitive habitats has become more difficult to manage. Killarney’s 1.54 million park visitors in 2025, along with nearly a million to Muckross House and over 367,000 to Killarney House and Gardens, represent a level of demand that strains management capacity.

Wicklow Mountains National Park faces particular pressure from its proximity to Dublin. Weekend and holiday footfall on popular trails like the Spinc Walk at Glendalough and the boardwalk at Diamond Hill in Connemara has reached levels that require active management interventions – one-way systems, timed entry, overflow parking and shuttle buses have all been considered or implemented at various sites.

The “Your Parks, Your Say” public consultation launched in October 2024 invited submissions on the future of Ireland’s national parks, signalling the NPWS’s intent to develop management plans that address growing visitor demand alongside conservation responsibilities. The consultation covered topics including infrastructure investment, access management, conservation priorities and the relationship between parks and local communities.
