Near Tumble the trail is closed due to a landslide, so be aware you cannot make it all the way through to crosshands.

At the heart of the Country Park is a lake, surrounded by a peat bog. Elsewhere are areas of heathland and broadleaved woodland. Facilities include a visitor centre, cafe and Mountain Bike and Tarmac / good quality bike trails.

Frequently Asked Questions

Are there many circular walks available around Llannon?

Yes, the area is well-suited for circular walks. Many trails are designed as loops, especially around the reservoirs and through local woodlands, allowing you to start and end in the same place without retracing your steps. This makes planning your hike straightforward.

What are the best options for an easy, family-friendly walk?

The trails around the Cwm Lliedi Reservoirs, also known as Swiss Valley, are ideal for families. The paths are generally gentle and well-maintained. For a shorter, accessible option, the Cwm Lliedi (Lower) Reservoir loop from Five Roads is a great choice for a peaceful walk through the woods by the water.

Are dogs allowed on the hiking trails near Llannon?

Most of the public footpaths and woodland trails in the Llannon area are dog-friendly. However, you will be walking through agricultural land with livestock, so it's essential to keep your dog on a lead and under control. Always be sure to clean up after your pet to keep the trails enjoyable for everyone.

Where can I find a hike with good views?

For panoramic views, a hike up Mynydd Sylen is highly recommended. As the highest point in the area, it offers expansive vistas over the Burry Estuary and Carmarthen Bay. Alternatively, the View of Carmarthen Bay loop from Carmel provides a gentler walk that still rewards you with lovely countryside and coastal scenery.

How difficult are the hiking trails in this region?

The hiking around Llannon caters to a range of abilities, but it's particularly good for easy and moderate walks. The landscape consists of low, undulating hills, so most routes involve gentle rather than steep climbs. Out of more than 50 routes in the area, the majority are classified as easy, with a good number of moderate options for those seeking a bit more of a challenge.

What do other hikers think of the trails around Llannon?

The trails are very well-regarded by the komoot community, with over 1,600 hikers having explored the area. Reviewers often praise the peaceful woodland paths, the scenic reservoir loops, and the variety of walks available through the rolling Carmarthenshire countryside.

Is it possible to get to the trailheads using public transport?

While some trailheads near villages might be accessible via local bus services, many of the best starting points, particularly for reservoir and hilltop walks, are more easily reached by car. It is recommended to check local bus schedules in advance, as services in rural areas can be infrequent.

Where is the best place to park for a walk in Swiss Valley?

For walks around the Cwm Lliedi Reservoirs (Swiss Valley), there are dedicated car parks available. The main car park for the lower reservoir provides direct access to the most popular circular trails. It can get busy during peak times, so arriving earlier in the day is a good idea.

Are there any walks that go through woodlands?

Yes, several trails take you through beautiful woodlands. The area around the Cwm Lliedi Reservoirs features a lovely mix of deciduous and coniferous trees. For a dedicated woodland experience, Mynydd Mawr Woodland Park is a popular local spot with a network of paths perfect for a forest walk.

Can I find any accessible, wheelchair-friendly paths?

For accessible trails, Llyn Llech Owain Country Park, a short drive from Llannon, is an excellent choice. The park features a network of well-surfaced footpaths, many of which are designed to be suitable for wheelchair users and pushchairs, allowing everyone to enjoy the unique heathland and woodland environment. You can find more details on their facilities at the Visit Wales website.

Are there any good pubs on or near the hiking routes?

Several traditional pubs can be found in the villages surrounding the main walking areas, such as Llannon, Felinfoel, and Five Roads. These are perfect for a post-hike meal or drink. It's best to plan a short drive from the trailhead to a nearby village to find the widest selection.
