The climb up to Bwlch-y-Groes from Llanymawddwy is a tough one. It is about 3.4 km long and has about 387 m of vertical ascent to get to the gap at 546 m above sea level. You will have an average gradient of 11.3% to grind away at, but you will be rewarded with fantastic views north and south.

Gorgeous area. Be aware the road/trail on the south side (including access to/from Llanymawddwy) are currently closed due to damage from storm Darragh. See https://www.hdcymru.co.uk/our-visitor-sites/lake-vyrnwy/storm-darragh/ for more details.

There is a little cafe above the main car park for a coffee and cake after the "gift shop" labelled walks. As usual, Komoot makes the walk easier than using signposts - remember to download to the phone app. Kayaking/canoeing around the lake is only possible for about half of it due to a protected bird sanctuary.

located in the old square it's a great place to stop for a brake, there's a great amount of outdoor seating either out in the sun or in the shade. With bike racks at hand and a lovely setting it's a good stop off.

Komoot offers a selection of 11 road cycling routes around Lake Vyrnwy, ranging from moderate to difficult. These routes allow you to explore the diverse landscapes of the Berwyn Mountains and the edge of Snowdonia National Park.
While many routes around Lake Vyrnwy feature significant elevation changes, the approximately 11.75-mile perimeter road around the lake is generally quiet and relatively flat, making it suitable for beginners or those seeking a leisurely ride. However, komoot's listed road cycling routes are primarily moderate to difficult, so families with younger children might prefer dedicated cycle paths if available, or consider the lake perimeter for a gentler experience.
For experienced cyclists seeking a challenge, the region offers demanding routes with significant climbs. A notable example is the Lake Vyrnwy Dam – Bwlch y Groes loop from Hendre Car Park, which includes the fearsome Bwlch y Groes, known as 'Hellfire Pass' and Wales's highest road. Another difficult option is the Bala Lake – Lake Vyrnwy Dam loop from Llangynog, connecting two major lakes with substantial elevation gains.
Road cycling around Lake Vyrnwy offers varied terrain. You'll find relatively flat sections, particularly around the lake's perimeter, but also significant elevation changes with challenging climbs and descents as routes ascend into the Berwyn Mountains and towards Snowdonia National Park. The landscape features unspoiled open countryside, extensive moorlands, and dense woodlands.
Absolutely. Cyclists can encounter several impressive landmarks and natural features. The Victorian-era Lake Vyrnwy Dam and the ornate Lake Vyrnwy Straining Tower are significant architectural sights. You might also pass by the Nant y Maes Waterfall, or explore the unique Giants of Vyrnwy forest and the Hand Sculpture of the Tallest Tree in the UK.
The entire region offers breathtaking vistas, especially as you gain elevation. Routes that ascend into the moorlands provide 360-degree views of the Berwyn Mountains. The View of Lake Vyrnwy highlight offers a classic perspective, and the challenging Bwlch y Groes climb rewards cyclists with extensive mountain views.
Yes, parking is available at various points around Lake Vyrnwy. Many routes, such as the Lake Vyrnwy Dam – Bwlch y Groes loop, often start from designated car parks like Hendre Car Park, providing convenient access for cyclists.
The spring, summer, and early autumn months generally offer the most favorable conditions for road cycling around Lake Vyrnwy, with milder weather and longer daylight hours. However, the region's natural beauty is captivating year-round, and each season brings its own charm. Always check local weather forecasts before heading out, especially for routes in higher elevations.

The time it takes depends on the specific route and your pace. A full circuit of the lake's perimeter road (approximately 11.75 miles) can be a leisurely ride. For more extensive routes, such as the Lake Vyrnwy – Lake Vyrnwy Straining Tower loop from Llangynog, it typically takes around 2 hours 24 minutes for a 30.4-mile (49.0 km) journey. Longer, more challenging routes can take upwards of 4 to 5 hours or more.
Road cycling around Lake Vyrnwy is unique due to its blend of stunning natural beauty, varied terrain, and remote setting within the Berwyn Mountains and bordering Snowdonia National Park. You'll experience everything from tranquil lakeside rides to challenging ascents with panoramic views, all while passing impressive Victorian architecture and diverse wildlife in an RSPB nature reserve.
