Top 14 Gorges in Gwynedd

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.

July 1, 2025, Devil's Kitchen (Twll Du)

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.

This typically includes a wetsuit (often provided by activity operators), sturdy footwear with good grip that can get wet, and a helmet.
