Moel Siabod is a terrific viewpoint as it is isolated from the other main peaks of Eryri. On the day I climbed it I was fortunate to experience an inversion, where the clouds form a layer below the summit.

Expect tricky terrain. It's very rocky and uneven with hidden holes.

The Castle of the Winds is a true highlight on this or any other mountain. Spectacular and spiky it makes for a great scramble over the top!

There are fantastic views of Snowdonia from the top of Moel Siabod, but the weather must be clear. From the top it is possible to see 13 of the 14 highest peaks in Wales on a clear day without turning your head.

Moel Siabod is a lonely mountain in Snowdonia, with a trigonometric point of almost 900 metres, above Betws-y-Coed and Capel Curig. The routes up can be easily varied to suit different needs and abilities, and are always beautiful, with views of 13 of the 14 highest peaks in Wales from the summit on a clear day – without turning your head! Good parking and a café at the foot make Moel Siabod a great day out every time. (Ordnance Survey)

You can't miss these two huge stones right on the summit of Tryfan. Traditionally climbers would jump from one to the other to gain the freedom of the mountain. But be warned people have died in the attempt.

Snowdonia National Park is home to many majestic peaks. Among the most popular are Snowdon Summit (Yr Wyddfa), the highest mountain in Wales, offering six distinct paths. Other highly regarded peaks include Penygadair summit, Cadair Idris, known for its imperious cliffs and views to the Irish Sea, and Glyder Fach summit, famous for its jumbled boulders and the Cantilever Stone.
For those seeking a challenge, Tryfan is renowned for its sharp ridges and scrambling opportunities, with the North Ridge being a classic. Crib Goch, part of the Snowdon massif, offers a rocky, knife-edge arête, recommended only for experienced mountain walkers with Grade 1 scrambling experience. Glyder Fawr also presents challenging routes like the Devil's Kitchen through steep crags and boulder fields.
While many peaks offer challenging routes, some paths on Snowdon, such as the Llanberis Path, are considered more accessible and can be suitable for families with older children or those looking for a less strenuous ascent. Moel Siabod also offers varied ascent options, including easy grass slopes, making it a good choice for a family day out with fantastic views.
Snowdonia's peaks boast diverse natural features. On Glyder Fach, you'll find the iconic Cantilever Stone and jumbled boulders. Glyder Fawr features the spectacular glacial valley of Cwm Idwal, home to Llyn Idwal and the Devil's Kitchen chasm. Cadair Idris is known for its impressive cliffs, enticing ridges, and scenic tarns. Carnedd Llewelyn offers grand corries and a large dome-shaped plateau.
The best time to visit Snowdonia's mountain peaks is generally during the warmer, drier months from late spring to early autumn (May to September). During this period, the weather is more stable, days are longer, and trails are typically in better condition. However, the weather in Snowdonia can change rapidly at any time of year, so always be prepared for all conditions.
Regardless of the season, always pack waterproof and windproof layers, sturdy hiking boots, a map and compass (and know how to use them), sufficient food and water, and a first-aid kit. In winter, additional gear such as crampons, an ice axe, and appropriate winter clothing are essential due to snow, ice, and rapidly changing conditions. Always check the weather forecast before heading out.
Parking is available at various trailheads across Snowdonia, though it can be limited and fill up quickly, especially during peak season. Popular starting points like Llanberis for Snowdon, or areas near Tryfan and the Glyderau, have designated parking. It's advisable to arrive early, especially for popular peaks, or consider using public transport or shuttle services where available.
Snowdonia National Park has a network of public transport options, including buses, that can take you to various trailheads. The Snowdon Sherpa bus service, for example, connects many of the main starting points for Snowdon. Planning your route in advance and checking bus schedules is recommended, especially outside of peak season, as services can be less frequent.
Many trails in Snowdonia are dog-friendly, but it's crucial to keep dogs on a lead, especially in areas with livestock, ground-nesting birds, or challenging terrain. Some routes, particularly those involving scrambling like parts of Tryfan or Crib Goch, may not be suitable for dogs. Always check specific trail guidelines and be mindful of your dog's capabilities and safety.
Beyond peak bagging, Snowdonia offers a wealth of outdoor activities. You can explore various waterfall hikes, enjoy gravel biking on trails like the Gwydir Mawr Trail, or go cycling around scenic lakes and valleys. The region also provides opportunities for rock climbing, wild swimming in tarns, and exploring historic quarries.
While Snowdon can be very busy, peaks like Carnedd Llewelyn in the Carneddau range offer wide-open views and opportunities for long days in the hills with fewer crowds. Moel Siabod, an iconic isolated peak, also provides a tranquil ambiance and superb panoramic views of the major ranges without the same level of foot traffic as Snowdon.
Visitors frequently praise the breathtaking panoramic views from the summits, especially on clear days, which can stretch across Snowdonia, Anglesey, and even to the Irish Sea. The diverse range of routes catering to all skill levels, from gentle inclines to challenging scrambles, is also highly valued. The sense of accomplishment from reaching a summit and the rich historical and mythical significance of the mountains add to the overall appeal.
