The Bearded Lake or Llyn Barfog is a pretty mountain lake below Mynydd y Llyn. It's fringed with water lilies and other plants which may explain its name. Legend has it that once a monster lived here, terrorising the local people. King Arthur came to rid the area of the menace, lassoing the monster with magical chains and dragging it out of the lake with his horse Llamrai. You can even see the horse’s footprint in a nearby rockface - Carn March Arthur.

A beautiful spot for a wild swim on the way up Cadair Idris. The rocks underfoot can be quite sharp and it gets VERY deep - the lake itself is something like 50m deep!

Llyn y Gader is a beautiful high mountain llyn beneath the intimidating north-facing cliffs of Cadair Idris. The Fox's Path brings you to the lake, before continuing up a rugged and tricky scree slope and gully to reach Cadair Idris' main Penygadair summit. The lake is a lovely spot for a halftime picnic or a wild swim.

Lake Vyrnwy features a 12-mile trail perfect for cycling and walking, along with many waymarked trails within its nature reserve. For more challenging hikes, the Minffordd Path leads to Llyn Cau and the Cadair Idris range. You can find various routes, including gravel biking, running, and MTB trails, in the wider area.

Yes, there are options for easier strolls. Dôl Idris Lake, at the start of the Minffordd path, offers a gentle stroll around its perimeter. The 12-mile trail around Lake Vyrnwy is relatively flat and suitable for cycling and walking. Llyn Tegid also has accessible lakeside paths.
The lakes boast stunning natural features. At Llyn Cau, you'll find pristine waters beneath the dramatic cliffs of Craig Cwm Amarch and Penygadair. The View of Llyn Cau from Craig Cwm Amarch offers an exceptional perspective of the cwm below. Lake Vyrnwy is surrounded by the RSPB Lake Vyrnwy Nature Reserve, featuring blanket bog, moorland, and woodland, plus the Rhiwargor waterfall and a gothic-style straining tower. Llyn Barfog (Bearded Lake) is fringed with water lilies, and Llyn Tegid is set amidst stunning mountain scenery.
The lakes are beautiful year-round, but the best time to visit generally depends on your preferred activities. Spring and summer offer warmer weather ideal for water sports, cycling, and longer walks. Autumn provides stunning foliage, while winter can offer dramatic, serene landscapes for experienced hikers, though some paths may be more challenging. Always check local conditions before your visit.
Yes, several lakes offer family-friendly experiences. Dôl Idris Lake is perfect for a gentle family stroll. Llyn Tegid (Bala Lake) is excellent for water sports like paddleboarding and canoeing, and the Bala Lake Railway offers a relaxed, scenic ride. Lake Vyrnwy provides cycling, walking, and birdwatching opportunities within its nature reserve, suitable for families.
Wild swimming is possible in some of the lakes for those brave enough. Llyn Cau and Llyn y Gader, both high mountain lakes, are mentioned as spots for wild swimming, offering a refreshing experience amidst dramatic scenery. Always exercise caution and be aware of water temperatures and conditions.
For a more tranquil experience, consider the high mountain lakes like Llyn Cau, Llyn y Gader, or Llyn Barfog (Bearded Lake). These often require a hike to reach, which naturally reduces visitor numbers compared to more accessible, larger lakes like Llyn Tegid or Lake Vyrnwy, especially during peak times.
Llyn Tegid (Bala Lake) is a prime location for water sports, including paddleboarding, canoeing, windsurfing, kayaking, and sailing. Fishing is also popular there, as well as at Llyn Trawsfynydd. While Lake Vyrnwy is a reservoir, it also offers opportunities for non-motorized water activities.
Many of the walking trails and outdoor areas around the lakes are dog-friendly, but it's always best to keep dogs on a lead, especially in nature reserves or areas with livestock. Specific rules may apply to certain areas, particularly around wildlife habitats like the RSPB Lake Vyrnwy Nature Reserve. Always check local signage.
The region is rich in wildlife. Llyn Tegid is home to the unique and critically endangered Welsh Gwyniad fish, along with pike, perch, and trout. Lake Vyrnwy, within its RSPB nature reserve, is a haven for birdwatchers, with species like peregrine falcons, pied flycatchers, and siskins. Ospreys are occasionally sighted at Llyn Trawsfynydd, which also boasts rich habitats for various wildlife in its surrounding woodlands and wetlands.
Several lakes are steeped in local folklore. Llyn Cau, nestled in the Cadair Idris range, is linked to legends of a terrifying serpent, the Afanc, and tales of giants. Llyn Barfog (Bearded Lake) has a legend of a monster that was lassoed by King Arthur's horse, Llamrai, whose footprint is said to be visible nearby. Lake Vyrnwy, while man-made, is a Victorian-era reservoir renowned for its striking gothic-style straining tower.
