Absolutely Gorge

While the cave gets its plaudits, the walk there and the surrounding wildlife isn’t too bad either. Following a rocky walk down, the gorge of the Afon Mellte attracts both ramblers and cavers for its striking view.

The cave is notably picturesque all year round. Looking out at the river from the mouth of the cave is lovely at all times of the year, with the light through the trees and the reflection off the water; it is beautiful scenery such as this that makes making it a popular haunt for photographers. Like much of “Waterfall Country”, you could spend hours here just drinking the atmosphere in. However, if you wish to go into the cave, you’ll need to do it with a qualified caving instructor. While popular, Porth yr Ogof is dangerous without proper care. The cave should also be avoided at times of rainfall, as the footpath can becomes slippery and cave hazardous.

Despite the small possibility of danger, Porth yr Ogof, thanks to its huge entrance, still looks like a caver’s paradise without even having to set foot in it.

Short and Snappy

At only 2,200m in length, Porth yr Ogof isn’t a time-consuming commitment, meaning it is ideal for those getting into caving or veterans who fancy a shorter, detail-packed cave. Despite not being the longest cave network in the world, Porth yr Ogof is filled with eye-catching caving landmarks and idiosyncrasies, mostly due to its limestone features.
The main cave is accessed by a smooth limestone walkway, with the first big landmark being the White Horse Pool, which gets its namesake from the white calcite vein accompanying the pool on the wall behind it.

Towards the end of the main entrance is the Resurgence Pool, which you should never cross. Signs here point cavers to alternative entrances given this section of the cave’s infamous reputation. Even though the Resurgence Pool looks small and easy to navigate, it isn’t. Following the Main Cave is The Maze, which is filled with holes to traverse the upper and lower levels of the cave. There are a couple of exits and entrances around here, but the cave has a few more secrets yet.

The Creek and Hywel’s Grotto is the next section of the cave, the former of which starts at the southern end of The Maze. Hywel’s Grotto is quite appealing to the eye, a small chamber made up of calcite pools, formations and pools.  An experienced caver and instructor will be able to guide you through the cave safely without missing any of its best features.
