The village of Abergwyngregyn (often shortened to Aber) is on the north coast of Wales, a few miles east of Bangor. The Mound: Pen-y-Mwd is a substantial, steep-sided, sub-circular earthwork. It is a classic Motte, which is the high mound of a motte-and-bailey castle. It measures roughly 22 feet (6.7 meters) high. Motte and Bailey: Traces of a surrounding ditch and a potential Bailey (the outer defensive enclosure) to the south-east have been identified. The motte itself has never been excavated.

Outside the former church stands the Capel Curig War Memorial, in the form of a Celtic cross, commemorating six soldiers who died in the First World War. The names of residents who served in the First World War and returned home are engraved on the sides of the plinth. The names of two men who died in the Second World War were added later to the plinth of the war memorial.

Our guide features 10 touring cycling routes that aim to minimize traffic, offering a range of experiences from moderate to difficult. While the immediate vicinity of Llyn Dulyn is very rugged and more suited to mountain or gravel biking, these routes are carefully selected in the broader Carneddau area to provide a quieter cycling experience.
The best time for touring cycling around Llyn Dulyn and the wider Carneddau region is generally from late spring to early autumn (May to September). During these months, you'll find more stable weather conditions, longer daylight hours, and less chance of the boggy or icy conditions that can make some routes challenging in winter. Always check local weather forecasts before heading out, as mountain weather can change rapidly.
While the Carneddau region is known for its challenging terrain, our guide does include 2 routes categorized as 'easy' that offer a gentler introduction to touring cycling with minimal traffic. For example, the route View of Eryri Hills and Coast – Llyn Anafon loop from Aber Falls provides a scenic, less demanding option.
The routes in this guide, while selected for minimal traffic, traverse the diverse terrain of the Carneddau mountains. You can expect a mix of quiet country lanes, some of which may be narrow or twisting, and potentially unpaved sections. Some routes feature steep gradients, reflecting the mountainous nature of the region. Cyclists should be prepared for varied surfaces and, on some routes, may need to dismount and push their bike for short sections.
Yes, many of the routes in this guide are designed as circular loops, allowing you to start and finish at the same point. For instance, the Conwy Castle – Conwy Town Walls loop from Rowen offers a moderate circular ride with historical points of interest.
While Llyn Dulyn itself is a remote and dramatic 'black lake' with historical significance, the touring cycling routes in the broader area offer views of the rugged Carneddau mountains, other remote reservoirs like Llyn Melynllyn, and glimpses of the unique Carneddau Ponies. Some routes may also pass by historical sites such as Conwy Castle, a UNESCO World Heritage site, or offer views towards the coast.
The area is highly rated by the komoot community, with an average score of 4.3 stars. Reviewers often praise the stunning, wild mountain landscapes, the sense of remoteness, and the challenge offered by the terrain. The quietness of the selected routes, away from heavy traffic, is also a frequently highlighted positive aspect.
Access to the more remote parts of the Carneddau, including Llyn Dulyn itself, can be challenging by public transport. While some routes may start near villages with bus connections, many require personal transport to reach the trailhead or parking areas. It's advisable to check local bus schedules and routes in advance, especially for the more secluded starting points.
Parking options vary depending on the specific route's starting point. Common starting points for routes in the wider Carneddau area often include designated car parks in villages like Abergwyngregyn or Llanfairfechan, or smaller lay-bys. For example, routes like View of Eryri Hills and Coast – Llyn Anafon loop from Abergwyngregyn typically start from areas with parking facilities. Always check the route details on komoot for specific parking recommendations.
Yes, for experienced touring cyclists seeking a challenge, our guide includes 4 routes rated as 'difficult'. These routes feature significant elevation gains and potentially more rugged or unpaved sections. An example is the Aber-Roth Pass Gravel Climb – Llyn Anafon loop from Llanfairfechan, which involves substantial climbing and demanding terrain.
While dogs are generally welcome in the Snowdonia National Park, it's crucial to keep them under close control, especially in areas with livestock like the Carneddau Ponies. Some routes may pass through private land or nature reserves with specific restrictions. Always check local signage and be mindful of other users and wildlife. For the safety of your dog and others, consider if the route's length, terrain, and potential for unpaved sections are suitable for your dog to accompany you on a bicycle.
