Standing at 821 metres above the Ogwen Valley, this rocky summit rewards those willing to tackle a proper mountain walk with sweeping views across Snowdonia's most dramatic peaks. The ascent from the A5 near Ogwen Cottage takes around two hours up steep, sometimes pathless terrain - not one for casual walkers in trainers.

Experienced hikers will love the challenge and the relatively quiet summit compared to busier neighbours like Pen yr Ole Wen. The ridge walk connecting to other peaks makes for a cracking full day out, though you'll need decent navigation skills when the mist rolls in.

Families with young children should give this one a miss - it's a serious mountain requiring proper boots, waterproofs and map reading ability. Come prepared for changeable weather, even in summer.

From holiday parks around Llanberis like Snowdon View Holiday Park or those near Ogwen Bank, you're well positioned for an early start. The nearby Ogwen Valley offers gentler walks if this proves too ambitious, while the A5 provides easy access from bases around Bangor. Allow a full day and check conditions before setting off - this peak demands respect but delivers views that'll stay with you long after you've descended.
