Y Garn is a fine hill, usually climbed from Ogwen Valley by it's West ridge, or as part of the walk along the Glyders range between Elidir Fawr and the Glyders themselves. There is however another way up, the East Ridge, which is a Grade 2 scramble and starts from Llyn Idwal.

Poor Elidir Fawr! It has been bashed about and big lumps knocked out of it at Dinorwic Quarry, it has had a power station built inside it, and has a reservoir for that reservoir almost at the very top. Fortunately when you climb it from Nant Peris you will only see the reservoir, the rest of the damage is ot of sight.

A high mountain with reasonable length walk-ins. Good scrambling route on it's north side that gives fine views of the 'Balck Ladders' cliff face.

Pen yr Ole Wen rises steeply above Llyn Ogwen, and the direct climb from near Ogwen Falls is uncompromising, but the views are superb.

Pen yr Ole Wen stands proudly as one of the iconic Welsh 3000s. I started my climb from the eastern side of the mountain. This route is a steady but demanding climb with the path being clear and walkable, though the incline gradually intensifies. Partway up the ascent, it is to be noted there is a short section of scrambling. While it adds a touch of adrenaline to the route, it remains accessible for most and requires only basic hands-on effort. This brief scramble injects a bit of excitement without being overwhelming Once at the top you are rewarded with panoramic views in all directions, my favourite being South, toward the rugged silhouettes of Tryfan, Glyderau range and beyond.

Pentir provides access to several impressive summits in the nearby Snowdonia mountain range. Notable peaks include Elidir Fawr Summit, known as the 'Electric Mountain' with extensive views, Carnedd Dafydd, the third-highest summit in Wales offering panoramic views, and Y Garn Summit, which provides views into Cwm Idwal and the Ogwen Valley.
Yes, the region around Pentir offers several challenging climbs. Pen yr Ole Wen, for example, has a steep, technical, and scree-filled ascent from the A5. The south ridge of Tryfan, often combined with an ascent of Elidir Fawr Summit, also offers a scrambling experience for those seeking variety.
The peaks offer diverse and spectacular views. From Carnedd Dafydd, you can see the Glyderau, Tryfan, Carnedd Llewellyn, and Anglesey. Y Garn Summit provides views into Cwm Idwal and up the Ogwen Valley, with lakes like Llyn Ogwen and Llyn Idwal visible. Moel Eilio Summit offers glorious views of Anglesey and the Irish Sea to the northwest, and Snowdon to the southeast.
Carnedd Dafydd is the third-highest summit in Wales, standing at 3,425 feet (1,044 m). Despite its height, it is generally less frequented than Snowdon, allowing for a more solitary experience of the wild mountain environment. It offers spectacular panoramic views over the Glyderau, Tryfan, Carnedd Llewellyn, and Anglesey.
Elidir Fawr Summit is known as the 'Electric Mountain' due to the Dinorwic Power Station located deep within its foundations. Its rocky summit ridge provides extensive views across Northern Snowdonia and to Anglesey. It's also the northernmost peak in the Glyderau range and can be combined with ascents of the Glyders and Tryfan.
The best time to visit Snowdonia mountains for hiking is generally during the warmer, drier months from late spring to early autumn (May to October). During this period, you'll typically find more stable weather conditions and longer daylight hours. However, always be prepared for changeable mountain weather, regardless of the season.
While many peaks in Snowdonia are challenging, there are options for family-friendly walks. For example, Moel Eilio Summit is easily ascended from Llanberis, and its grassy slopes can be more approachable for families. Always check specific route details for suitability and difficulty before heading out with children.
Beyond hiking, the area around Pentir offers various outdoor activities. You can explore road cycling routes like 'The Menai Straight, Caernarfon Castle & Llyn Cwellyn loop' or 'A clockwise loop around Anglesey'. Mountain biking is also popular, with trails such as 'Telegraph Valley (Maesgwm) – Snowdon Ranger Hostel loop'. For more details, check the Road Cycling Routes around Pentir or MTB Trails around Pentir guides.
While Pentir itself is a farming community, nearby areas like Llanberis and the Ogwen Valley offer amenities. Llanberis, being a popular base for Snowdonia, has various cafes, pubs, and accommodation options. The Ogwen Valley also has facilities, particularly around the A5, which serves as a starting point for many mountain routes.
Pen yr Ole Wen is an almost pyramidal peak that serves as a gateway to the Carneddau mountain range. It offers excellent views of the Glyderau. There are two main ascent options from the A5; the direct route from the Youth Hostel is challenging, while the trail via Ffynnon Lloer from the eastern end of Llyn Ogwen is slightly easier, though still demanding.
Yes, many of the mountain ascents in Snowdonia can be incorporated into circular routes. For instance, the classic loop for Moel Eilio Summit is from Llanberis, continuing along the ridge past Foel Goch to Bwlch Maesgwm, and then descending back to Llanberis. The Glyder Horseshoe is another superb outing that includes peaks like Y Garn Summit.
The Snowdonia National Park, encompassing the mountains around Pentir, is rich in wildlife. Hikers may spot various bird species, including buzzards, ravens, and peregrine falcons. Keep an eye out for feral goats on higher slopes and, if you're lucky, you might catch a glimpse of the elusive wild ponies or stoats.
