Embark on the Llyn Idwal loop from Ogwen Cottage, an easy 3.0-mile (4.8 km) hike that takes about 1 hour and 32 minutes to complete, with an elevation gain of 658 feet (201 metres). You will experience a dramatic glacial landscape with rugged, rocky terrain and uneven paths. The trail offers spectacular views of the crystal-clear Llyn Idwal, nestled within Cwm Idwal, and is framed by towering peaks like Tryfan and Glyder Fawr. Keep an eye out for the prominent Idwal Slabs, popular with rock climbers, and cascading streams along the way.
Starting from Ogwen Cottage, this route is generally accessible for most fitness levels, providing a mountain experience without excessive physical effort. However, some sections are moderately strenuous with steep, rough mountain paths, especially as you gain height towards the southern end of the lake. Due to the stony and sometimes boggy ground, sturdy hiking boots are essential for sure-footedness, particularly after rain. The path is not suitable for wheelchairs or pushchairs.
This area is home to Cwm Idwal National Nature Reserve, Wales' first, renowned for its impressive ice-sculpted landscape and unique plant life. The crater-like Cwm Idwal is a result of significant geological activity, making it one of the best places to observe glacial aftermath in the National Park; Charles Darwin even conducted scientific work here.

Scenic stiles in Snowdonia—like those near Cwm Idwal, the Ogwen Valley, or Devil’s Kitchen—offer framed viewpoints of rugged peaks, glacial lakes, and stone walls. Photographers use these rustic wooden stiles as foreground elements to capture classic compositions of towering Welsh mountains like Tryfan and Pen yr Ole.

A reminder of when the area was heavily worked, part of the old Slate Level. This is not the Devil's Kitchen, which is high up on Cwm Idwal.

Pen yr Ole WenClick to open side panel for more information is the seventh-highest mountain in Wales and the southernmost peak of the Carneddau range. Standing at 978 meters (3,209 feet), its distinctive pyramid shape dominates the northern skyline of the Ogwen Valley, directly facing the jagged peaks of Tryfan and the Glyderau. Challenging Ascents: The mountain is famous for its steep, unrelenting climb from Ogwen Cottage. The most direct route involves a breathless scramble up the south ridge, which quickly gains height and provides dramatic aerial views of Llyn Idwal below. Panoramic Views: From the summit, you are rewarded with one of the finest 360-degree vistas in Eryri, looking deep into the glacial trough of Nant Ffrancon and across to the Snowdon massif. Gateway to the Carneddau: It serves as the primary gateway for hikers embarking on the long, high-altitude traverse toward Carnedd Dafydd and Carnedd Llewelyn, the range's higher neighbors. Rugged Terrain: Unlike the more popular Snowdon paths, Pen yr Ole Wen offers a wilder, rockier experience that requires good navigation skills, especially when cloud descends on its broad, stony plateau.
