This route was planned by komoot.
The Komoot tour for this loop is approximately 180 km (112 miles) and is rated as difficult. While keen cyclists might attempt it in one long day, we recommend planning for two days to fully enjoy the diverse scenery, towns like Westport Town Centre and Newport, and the unique experience of the ferry crossings.
The terrain is quite varied. A significant portion follows the Great Western Greenway, which is a largely flat, paved, off-road path built on a former railway line. However, on Achill Island, you'll encounter local roads with moderate climbs and a particularly steep descent/ascent along the spectacular Atlantic Drive Road. Be prepared for some challenging sections, especially if you include the optional Clare Island loop.
Due to its length (180 km), significant elevation gain (1278m), and challenging sections on Achill Island, this full loop is rated as difficult and is not ideal for beginners. The Great Western Greenway sections are more accessible, but the entire route requires a medium to good level of fitness and experience with road cycling, including navigating some narrow Irish roads.
The best time to cycle this loop is generally from late spring to early autumn (May to September). During these months, you'll typically find milder weather, longer daylight hours, and more reliable ferry schedules. Always check the local forecast before you go, as coastal weather in Ireland can change quickly.
While the Great Western Greenway sections are generally dog-friendly (on a leash), the full loop involves local roads and ferry journeys. Policies for dogs on ferries can vary, so it's crucial to check with the specific ferry operators for Clare Island and Achill Island in advance. Always keep your dog on a leash, especially near livestock and on shared paths.
No, you do not need any specific permits or pay entrance fees to cycle the Clew Bay and Achill Island loop. However, you will need to pay for the ferry crossings to and from Clare Island, and potentially for the Achill Sound Bridge depending on your exact route, if not already included in a bike hire package. Bike hire is readily available in towns like Westport, Newport, Mulranny, and Achill.
The loop can be started at any point and cycled in either direction, offering great flexibility. Popular starting points include Westport Town Centre or Newport, both of which offer parking facilities. If you're renting a bike, the rental shop can often advise on the best starting location and parking options.
This loop is renowned for its magnificent coastal scenery. You'll enjoy Wonderful views of Clew Bay, including View of Carrowmore Hill and Croagh Patrick. On Achill Island, the Atlantic Drive Road and Achill Coast Road offer breathtaking vistas of the Wild Atlantic coastline, sea cliffs, and sandy beaches. You'll also pass through charming towns and over the Achill Sound Bridge (Gob an Choire).
Yes, this loop incorporates significant sections of the Great Western Greenway, a world-class car-free path. It also overlaps with parts of the EuroVelo 1 and The National Coastal Trail, offering a diverse cycling experience that connects you to broader Irish and European cycling networks.
Absolutely! The route passes through several towns and villages such as Westport Town Centre, Newport, Mulranny, and various settlements on Achill Island. These places offer a good selection of cafes, pubs, and restaurants where you can refuel and enjoy local hospitality. It's always a good idea to carry some snacks and water, especially for longer stretches between towns.
Given the varied terrain and coastal weather, layers are key. Bring waterproof and windproof outer layers, even in summer. Padded cycling shorts are highly recommended for comfort on longer rides. Don't forget a helmet, sunglasses, sunscreen, a repair kit, plenty of water, and snacks. A charged phone and a map (or the Komoot app with the tour downloaded) are also essential.
