The Ring of Kerry concentrates the entire character of Ireland’s western coastline into a single day’s loop — mountain passes, beehive huts, Atlantic islands, and a Dark Sky Reserve that holds gold-tier status. This guide pairs the route with 12 eco-certified hotels in the four towns that make natural overnight stops, alongside an honest comparison of how to travel it: car, bus, or bike.
About the Ring of Kerry
The Ring of Kerry is a 179-kilometre signed scenic loop around the Iveragh Peninsula in the south-west of Ireland, generally driven, cycled, or coached from Killarney as the gateway town. The route uses the N70 national secondary road for most of its length, with optional spurs onto the Skellig Ring (around the western tip via Portmagee) and the Kerry Way long-distance walking path which shadows it inland. The loop typically takes 3.5 hours of pure driving time, but most visitors take a full day because of the volume of viewpoints, beaches, and villages along the way.
Killarney is the obvious base for almost everyone: it sits at the eastern end of the Ring, has the only railway station on the peninsula, and is surrounded by Killarney National Park — the oldest in Ireland, founded in 1932. Beyond Killarney, Kenmare (at the southern end of the Ring), Sneem and Caherdaniel (on the southern coast), and Cahersiveen and Portmagee (on the western edge) all make good secondary bases for travellers who want to spread the loop over two or three days.
Kerry holds something rarer than scenery: a designated International Dark Sky Reserve, awarded gold-tier status by DarkSky International in 2014. The Kerry Reserve covers roughly 700 square kilometres of the Iveragh Peninsula between Kells and Caherdaniel, and at the time of writing it remains one of only around 20 gold-tier reserves globally and the only one in the Northern Hemisphere covering this latitude band. The practical effect is that on a clear winter night, in the Reserve’s core zone, the Milky Way is visible to the naked eye from sea level — something that is no longer true in most of Western Europe.
Driving vs Bus vs Cycling
The carbon arithmetic of the Ring of Kerry is unusually clean to calculate because the loop is fixed at 179 km. A petrol car at the EU 2024 fleet average of 113 g CO₂/km emits about 20.2 kg CO₂ for the full loop, or 10.1 kg per person at double occupancy. A diesel car runs slightly lower at around 18 kg. An electric vehicle charged from the Irish grid (still roughly 40% fossil at time of writing) comes out at about 7 kg for the whole loop, falling to under 2 kg if you happen to charge from a hotel’s on-site solar.
The Bus Éireann route 270 series circles the Ring during the summer season, with a guided coach option also running from Killarney throughout the year. A full coach at typical occupancy works out to roughly 2.5–3 kg CO₂ per passenger for the loop — meaningfully better than a half-full car. Cycling the Ring is, predictably, the lowest-carbon option (effectively zero on operations) but it is also the most demanding: the N70 is narrow, the elevation gain is around 1,800 metres over the loop, and there is no continuous segregated cycling infrastructure. Most cyclists tackle it over two days with an overnight in Cahersiveen, Waterville, or Caherdaniel.
One specific recommendation: drive the Ring anti-clockwise from Killarney via Killorglin first. The N70 is officially a two-way road but the tour coaches all run clockwise, and meeting one on a blind bend with a stone wall on the seaward side is the most stressful experience available on the loop. Going anti-clockwise puts you behind the coaches rather than head-on into them, and the coaches stop at the same viewpoints, so you’ll overtake them naturally during their breaks.
The 12 Eco Hotels Around the Ring
The Europe Hotel & Resort, Killarney
The Europe is the largest five-star property in the south-west of Ireland with 187 rooms on the shore of Lough Lein, looking directly across to MacGillycuddy’s Reeks. It has held Green Key certification since 2018 and runs a 600 kW biomass boiler that handles essentially all space and water heating across the resort. The kitchens use a Killarney 30 km radius sourcing policy. The lakeside footpath connects directly to Killarney National Park’s trail network. View The Europe Hotel →
Aghadoe Heights Hotel, Killarney
Set on the ridge above Killarney with the best long view in the town — Lough Lein in the foreground, the Reeks behind — Aghadoe Heights has 74 rooms and completed a major retrofit in 2024 that added rooftop solar (180 panels) and replaced the gas-fired pool heating with an air-source heat pump. Green Hospitality Silver. A 10-minute drive or 8 km cycle from Killarney centre, which keeps it slightly removed from the town’s busiest streets. View Aghadoe Heights →
The Killarney Park Hotel, Killarney
A 68-room townhouse hotel in the centre of Killarney owned by the Treacy family, who were among the founders of the Killarney Sustainability Network in 2019. The hotel’s restaurant works exclusively with Kerry suppliers and the property has been carbon-balanced on operations since 2022. The garden behind the hotel is one of the quietest spots in the town centre. For more accommodation in the area see our guide to eco-hotels in Killarney. View Killarney Park →
The Brehon, Killarney
A 125-room hotel directly opposite the entrance to Killarney National Park, with the INEC concert venue attached. Green Hospitality Gold. The Brehon’s energy strategy is unusually integrated with the INEC — surplus heat from the venue’s HVAC is recovered into the hotel’s hot water system, which the management estimates saves around 90 tonnes of CO₂ per year. The location means you can walk into the National Park before breakfast. View The Brehon →
Cahernane House Hotel, Killarney
A 38-room country house at the end of a private avenue inside the National Park boundary, Cahernane is a small property that has prioritised retaining the historic fabric of the 1877 building while quietly upgrading the systems behind the walls. The kitchen garden has been organic-certified since 2020. Free electric bike loans for residents heading into the park. View Cahernane House →
Sheen Falls Lodge, Kenmare
The southern-end equivalent of The Europe — a 66-room country house estate on 121 hectares above the Sheen waterfall. Sheen Falls runs a private hydro turbine on its own river, holds Green Key, and opens its forest trail network to non-residents. It is also one of the better stargazing bases in the Kerry Dark Sky Reserve’s eastern buffer zone. View Sheen Falls →
Park Hotel Kenmare
An 1897 railway hotel above Kenmare Bay with 46 rooms and one of the most serious culinary programmes in the south-west. Park Hotel Kenmare has been Green Hospitality Gold since 2020 and runs an unusually transparent operation — annual environmental reports are published on the hotel’s website. The terrace gardens, walled kitchen garden, and woodland walk down to the bay are all part of a single conservation scheme registered with Kerry County Council. View Park Hotel Kenmare →
Brook Lane Hotel, Kenmare
A 21-room boutique on the edge of Kenmare town, Brook Lane is the most practical eco-stay in the area for travellers without a car — the town bus stop is a five-minute walk away, and the Beara Way trailhead starts at the next corner. Green Key certified. The owners run a 100% Irish-suppliers policy in the kitchen and donate the food waste stream to a local biogas plant in Killorglin. View Brook Lane →
Sneem Hotel, Sneem
Sneem Hotel sits on Goldens Cove at the western edge of the village, with 69 rooms looking across Kenmare Bay to the Beara Peninsula. The property completed a 200 kW heat pump installation in 2023 and was awarded Green Hospitality Silver later that year. Sneem itself is the natural midpoint stop on the Ring of Kerry loop, and the hotel runs a Dark Sky stargazing session most clear evenings between October and March. View Sneem Hotel →
Derrynane Hotel, Caherdaniel
The Derrynane is a 70-room family-run property looking down on Derrynane Bay and the National Historic Park around Daniel O’Connell’s house — easily the most beautifully sited hotel on the Ring. Green Hospitality Silver. The hotel sits squarely inside the core zone of the Kerry Dark Sky Reserve, and the management have replaced all external lighting with downward-shielded warm-amber fittings to comply with the Reserve’s lighting protocol. View Derrynane Hotel →
Ring of Kerry Hotel, Cahersiveen
A 35-room property in Cahersiveen town with direct access to the South Kerry Greenway trailhead — the new traffic-free cycling route that runs from Glenbeigh to Cahersiveen along the old railway line. The hotel offers secure bike storage and a wash bay, and the kitchen sources from the suppliers along the Skellig Coast Food Trail. Fáilte Ireland Sustainability Assurance mark since 2024. View Ring of Kerry Hotel →
The Moorings, Portmagee
A 16-room guesthouse on Portmagee’s working pier, The Moorings is the natural overnight base for travellers heading out to Skellig Michael — the boats leave from the harbour outside the door. The owners replaced the building’s oil heating with an air-source heat pump in 2023 and the kitchen is supplied almost entirely by the Skellig Coast inshore fleet. Quietly one of the most low-impact stays in the south-west, with a Failte Ireland Sustainability Assurance mark since 2024. View The Moorings →
What to Stop For
Skellig Michael. The UNESCO-listed monastic island 11 km off the Iveragh coast is the most carefully managed visitor site in Ireland. The Office of Public Works restricts landings to 180 visitors per day across 15 licensed boat operators, and the season runs only mid-May to early October. Book through a Portmagee operator several months in advance.
Muckross Estate, Killarney National Park. The 4,300-hectare park is one of the few sites in Ireland where you can still hear native woodland in spring — Reenadinna Wood holds the largest remaining yew forest in Europe. The estate is car-free in its core zone (Muckross House to Torc), accessed by jaunting car, electric shuttle, or bike.
Torc Waterfall. A 20-metre cascade three kilometres south of Muckross, reached by a 200-metre walk from the N71 layby. The waterfall is the lower outflow of the Owengarriff river, which drains the Mangerton Mountain catchment. The lower viewing platform is wheelchair-accessible.
Ladies View. The classic Ring of Kerry viewpoint, named for Queen Victoria’s ladies-in-waiting who admired it during the 1861 royal visit. The view stretches west over the Upper Lake of Killarney into the MacGillycuddy’s Reeks. Two car parks; arrive before 10am or after 4pm in peak season.
Staigue Stone Fort. A 2,500-year-old drystone ringfort above Castle Cove, one of the largest and best-preserved in Ireland. The site is in state care, open year-round, and free to enter. A short uphill walk from the small car park; allow 45 minutes.
Kerry Cliffs. A privately managed clifftop site near Portmagee, with the highest sea cliffs on the Ring at 305 metres. The visitor centre operates on solar and a small wind turbine, with all proceeds reinvested in the local community trust. The Skellig Islands are clearly visible offshore on a clear day.

Frequently Asked Questions
How long does it take to drive the Ring of Kerry?
Pure driving time around the 179 km loop is approximately 3.5 hours, but a realistic day trip takes 7–9 hours once you factor in stops at Ladies View, Muckross, Sneem, Waterville, and the Kerry Cliffs. Most visitors prefer to split it over two days with an overnight in Kenmare, Sneem, or Cahersiveen, which makes the trip much less hurried and frees up an evening for Dark Sky Reserve viewing.
Can you do the Ring of Kerry without a car?
Yes. Bus Éireann’s 270-series routes and the seasonal Ring of Kerry coach tour both circle the loop from Killarney, with the coach tour stopping at all the major viewpoints. The new South Kerry Greenway (Glenbeigh–Cahersiveen) adds a traffic-free cycling option for part of the western section. Cycling the full loop is possible but demanding — most riders take two days.
Why drive the Ring anti-clockwise?
Tour coaches drive the Ring clockwise (Killarney → Kenmare → Sneem → Waterville → Cahersiveen → Killorglin → Killarney), which means meeting them on the narrow seaward bends is unavoidable if you drive in the same direction. Going anti-clockwise puts you behind the coaches rather than head-on into them on blind corners, and you’ll naturally overtake them at viewpoint stops without losing time.
When is the best time of year for the Ring of Kerry?
May, June, and September are the sweet spots — long daylight, the Skellig boats running, and fewer coaches than peak July–August. For Dark Sky Reserve stargazing, October through March gives much longer nights and clearer skies, with new-moon weeks producing the best viewing. The Ring is open year-round but several boat operators and smaller restaurants close from November to February.
Where is the best base for stargazing in the Kerry Dark Sky Reserve?
Caherdaniel and Portmagee sit within the Reserve’s core zone, which has the darkest skies. The Derrynane Hotel in Caherdaniel and The Moorings in Portmagee are both inside the Reserve and have adopted the Reserve’s lighting protocol. Sneem is on the eastern edge of the buffer zone and is still genuinely dark. Killarney itself is too brightly lit for serious astronomy, but Aghadoe Heights, on the ridge above the town, is workable on a clear night.
