Ireland Eco-Hotels
Here is a map to see where these eco-hotels are located:
Cashel Palace Hotel
Cashel Palace Hotel offers a luxurious escape steeped in history, set amid the vivid landscapes of County Tipperary. Guests can unwind in elegant rooms and spa facilities, enjoy fine dining on locally sourced produce, and explore the nearby Rock of Cashel and rolling countryside.
True to its heritage, the hotel champions eco-conscious practices—its new wings are built to NZEB (Nearly Zero Energy Building) standards, using LED and photosensitive lighting, underfloor heating with night-time electricity, and individually controlled climate systems. The estate also features an on-site water well and composts food waste into rich garden compost, showcasing its commitment to sustainability.
Kilkea Castle
Kilkea Castle invites guests to experience Ireland’s heritage in a setting that seamlessly blends medieval charm with contemporary luxury. Located just an hour from Dublin, this 12th-century castle offers elegant suites, tranquil self-catering lodges, a relaxing spa, and a championship golf course set amidst sprawling parkland. Guests can explore the rich history of the estate, unwind with fine dining, or simply stroll the peaceful grounds that surround the oldest continuously inhabited castle in Ireland.
The estate is equally dedicated to environmental stewardship. A landmark 791 kW solar PV system supplies clean energy to the property, cutting down annual CO₂ emissions by approximately 200 tons. Smart building management, energy-efficient insulation, EV charging stations, and a modern wastewater treatment system all contribute to its low-impact operations. By reducing reliance on fossil fuels and actively investing in sustainable infrastructure, Kilkea Castle sets a compelling example of how historic properties can adapt to a greener future without sacrificing comfort or charm.
Dromoland Castle
Dromoland Castle combines historic grandeur with modern five-star amenities in the heart of County Clare. Originally the ancestral seat of the O’Briens of Dromoland, this 16th-century estate now offers refined accommodations, a tranquil spa, gourmet dining, and a championship golf course set within 500 acres of wooded parkland and lakeside scenery. Guests can enjoy the castle’s rich heritage and landscaped grounds while also discovering nearby natural and cultural landmarks such as the Cliffs of Moher and The Burren.
The estate is increasingly committed to reducing its environmental footprint through energy-saving upgrades, responsible waste management, and prioritizing local sourcing within its culinary program. Sustainability efforts continue to grow in line with Ireland’s broader push toward eco-conscious tourism, reflecting how historic properties can adapt to meet modern environmental standards while preserving their unique character.
Gregans Castle Hotel
Gregans Castle Hotel captures the essence of Ireland’s Burren landscape from its historic 18th-century manor perched above Galway Bay. This family-run retreat offers elegantly appointed country house rooms, a celebrated fine-dining restaurant, and serene gardens that reflect its literary and artistic legacy—Tolkien and Seamus Heaney once found inspiration here. Guests are enveloped in a blend of cozy fireside lounges, natural slate-clad surroundings, and sweeping views of rugged limestone landscapes.
Equally impressive is the hotel’s commitment to environmental stewardship. Gregans has adopted sustainable practices like bottling spring water from its own mountain source, composting food and garden waste, using biomass and low-energy systems, and powering operations with solar and wind energy. A productive vegetable garden is nurtured via a solar-pumped well, while tree-planting efforts support native wildlife and the Burren Pine restoration. As a founding member of the Burren Ecotourism Network and a recipient of Europe’s most eco-friendly hotel accolades, the hotel demonstrates that heritage and ecological responsibility can coexist beautifully.
The Lake Hotel
The Lake Hotel offers a heritage-rich escape nestled on the shores of Lough Leane in County Kerry. This family-owned, four-star establishment blends traditional Irish charm with modern comforts—featuring refined lake-view rooms, luxurious thermal suites, serene lounges, and exquisite dining that incorporates locally sourced ingredients. Its location within Killarney National Park allows guests to enjoy stunning natural scenery and wildlife, from roaming deer to majestic eagles soaring over the lake.
The hotel has made significant investments in sustainability and environmental stewardship. Its initiatives include solar panel installation, energy-efficient lighting and insulation upgrades, eight electric car charging stations, and a renewable energy-powered boiler. Water is drawn from a natural well filtered through limestone, and the hotel abstains from using chemicals. Additional eco-conscious measures include planting over 1,700 trees, establishing rewilding areas, maintaining on-site beehives for honey and biodiversity, and growing herbs and vegetables for its menus.
Ashford Castle
Ashford Castle stands as a living testament to Ireland’s cultural heritage, offering immersive, high-end experiences across its historic estate in County Mayo. Guests can participate in “Exceptional Irish Experiences” that highlight the richness of western Ireland—from foraging in the castle’s Kitchen Garden to intimate culinary encounters with local producers, artisanal crafts, storytelling, music, literary traditions, and more. These curated itineraries connect visitors directly with the region’s traditions while supporting local communities.
At the heart of its sustainability efforts, Ashford Castle runs an on‑site apiary and promotes eco-conscious experiences to align with its environmental values. Additionally, the property supports ongoing social initiatives such as recycling partially used toiletries through partnerships with organizations like CleanConscience.
Falls Hotel & Spa
The Falls Hotel & Spa is a family-owned retreat nestled beside the cascading River Inagh in County Clare, within the Cliffs of Moher & Burren UNESCO Global Geopark. Its location—on a 50-acre wooded estate—offers guests serene riverside and woodland walks, elegant accommodations, a relaxing spa, and an invitation to explore the dramatic landscapes of the Wild Atlantic Way.
Sustainability is deeply embedded in its operations. The hotel has been certified carbon-neutral through the GreenMark program by Green Hospitality Ireland, having reduced emissions by approximately 90% over five years through renewable energy and efficiency initiatives. One standout project is the installation of a 220 kW hydroelectric turbine on the adjacent river, which can provide 100% of the property’s electricity when conditions allow. Additional eco-practices include solar panels, elimination of single-use plastics, water-saving fixtures, compostable packaging, two EV charging points, on-site beehives, wildflower gardens, and support for local producers.
