Aberglaslyn Pass: A Dramatic Walk Through Snowdonia’s Wild Side
The Aberglaslyn Pass is one of Snowdonia’s most spectacular natural features, a narrow, rocky gorge where the River Glaslyn carves its way through steep cliffs and woodland between Beddgelert and Nantmor. This short but powerful section of the valley is packed with drama, beauty, and a sense of ancient mystery. With rushing rapids, moss-covered boulders, and twisting woodland paths, it’s a favourite spot for walkers, photographers, and anyone who wants to experience Snowdonia’s wilder side up close.
A Riverside Walk Through One of Snowdonia’s Wildest Gorges
From the moment you step onto the trail, the sound of the river pulls you in. The path hugs the water’s edge, sometimes just metres above the fast-flowing river. It winds through a mix of oak woodland and rocky outcrops, with occasional footbridges and stepping stones adding a sense of adventure.
The most popular way to explore the pass is via the Fisherman’s Path, a historic trail that clings to the rock walls beside the river. Originally used by anglers, this narrow route gives you a front-row seat to the river’s power, especially after heavy rain when the water surges through the gorge.
Along the way, you’ll pass through tranquil woodland, spot ancient mining remnants, and perhaps catch sight of a dipper or heron darting along the riverbank. The walk is short but rich in atmosphere and perfect for those looking to experience Snowdonia’s rugged beauty without climbing a mountain.
