Best canyons in Gwynedd are often found within the county's mountainous landscapes, where ancient watercourses have carved impressive gorges and canyon-like features. These natural geological formations offer diverse terrain for outdoor activities. Gwynedd's numerous river corridors, originating in Snowdonia, contribute to these formations, ranging from fast-flowing upland streams to wider rivers. The abundant rainfall in Wales has played a significant role in shaping these natural features.

After the rest stop at Llyn Y Cwn we descend and pass the Devil's Kitchen (Twll Du) again. The descent is as strenuous as the climb. The path, as far as can be seen, is quite steep in places. Then it becomes a matter of paying attention, scrambling and searching for the next section of the path. This is not such an easy part of the route. You have to use your hands and feet to conquer the steepest parts.

A little tunnel... I'm not sure where it goes but it's a handy place to shelter if it's tipping it down. ⛈️

Great walk through a variety of tree species and easy to follow path. Would recommend going anti clockwise/reverse of suggested route as scenery coming back through gorge is stunning (with the bridge as a nice suprise at the end) and easier downhill as plenty of small steps. If taking a dog then be aware there is/are sheep grazing along the route but no stiles or fences to climb if you have a large dog but there are very steep banks/drops along the gorge so recommend keeping on a lead if they are a bit hectic! Would not recommend unless you have a basic level of fitness as some parts of the path are extremely steep.

Visitors also enjoy Afon Gain Gorge on the Minotaur Trail, which features forest, river, and bridge elements with progressive challenges.
Yes, some gorges offer experiences suitable for families.

Gwynedd's gorges showcase a variety of stunning natural features. You'll encounter powerful rivers, dramatic waterfalls like those at Coed Ganllwyd National Nature Reserve and Cynfal Falls (Rhaeadr Cynfal), and unique geological formations such as the distinctive crack at Devil's Kitchen (Twll Du). Many areas are surrounded by ancient oak woodlands, creating a 'rainforest-like' environment, especially in canyoning locations.
The best time to visit Gwynedd's gorges and canyons is generally during drier periods, typically late spring to early autumn. While the abundant rainfall contributes to their formation, wet conditions can make paths slippery and rivers turbulent, especially in narrow passes like The Aberglaslyn Pass. Always check local weather forecasts before your visit, and avoid walking in 'spate' (flood) conditions.
Beyond exploring the gorges themselves, Gwynedd offers a wide range of outdoor activities. You can find numerous hiking trails, from moderate to difficult, including routes up Snowdon and Cadair Idris. For more adventurous pursuits, there are mountain hikes and running trails. You can find more information on these activities in the Hiking in Gwynedd, Running Trails in Gwynedd, and Mountain Hikes in Gwynedd guides.
For canyoning or gorge walking, it's essential to wear appropriate gear. This typically includes a wetsuit (often provided by activity operators), sturdy footwear with good grip that can get wet, and a helmet. Layers of quick-drying clothing underneath a wetsuit are also recommended. Be prepared for wet and potentially cold conditions, even in summer, due to the water and shaded environments.
