Porth yr Ogof is a massive cave entrance located on the Gower Peninsula in Wales, UK. The cave mouth is 20 meters high and 60 meters wide, making it one of the largest cave entrances in Britain. The cave is situated on the coastline, and at high tide, the sea flows into the cave, creating a unique and dramatic sight. The cave's interior is dark and mysterious, with ancient limestone walls and a sandy beach. Visitors can explore the cave at low tide, discovering hidden pools and ancient fossils embedded in the rocks. The area surrounding the cave is also of great interest, with a variety of wildlife and flora thriving in the unique coastal environment.
Really great starting point for the waterfall hike. Water levels vary and we had a good time standing in the river for a bit and watching. Please be careful as I'm sure levels rise easily and the river can gain strength fast. We also saw a cool section of water rushing under the rocks on the way down.
Fantastic place. The waterfall runs underground and there's a plan of the underground cave system in the carpark above. It should only be entered by experienced cavers. It's interesting to see
We parked in a small car park which cost PS5.00 for the day. Roads are very narrow but one way which is great. Drive slowly as the car park is on your right. They had a sign car park full but it wasn't so check with staff at shop or entering car park. A small shop and staff on site offering good information about the path, waterfall and cave. Toilets are available via porto loo or main toilets but very dirty. Walk down path next to car park is the cave. Rocky and muddy steep path so be careful. Make sure you have good footwear. The cave has open access to explore and entry is free. Its muddy, wet and slippery inside so be advised about risk trips and falls. Walk slowly and carefully. Take a head torch and torch with you if you want to explore the opening sections of the cave. We were advised by a club doing cave exploring which section are safe enough to explore, so don't go exploring; if you do only go to areas which are safe to do so!! Some areas are narrow so bending down low and walking on you hand and knees is required and be prepared for your clothes to get dirty. Overall a good experience for family and kids. The entrance area is ok for smaller children. Its worth exploring first before you start doing the four water falls walk or afterwards your choice.
Amazing big cave. Have few corridors inside. A dam made of tree roots, you can go around it. Behind the dam, you can go deeper. A very interesting place. Nice cave.
Porth yr Ogof has the largest cave entrance in Wales and one of the largest in the UK standing at nearly 20 metres (66 ft) wide and 8 metres (26 ft) high. There are over 15 entrances to this cave system and while the dry sections are great to explore (with experienced cavers) the wet sections are now blocked with trees and debris. As is the resurgence so I wouldn't recommend going in at present until it is cleared. Check with Caving clubs local SWCC etc. DO NOT PLAY in caves unless you know what you're doing. That said a short walk down the rocky steps brings you to this beautiful entrance with the river running into it. After a downpour the river will be raging, in gentle times it simply trickles but there are deep pools as you'll see just before you enter the mammoth sized entrance, you'll feel the temperature drop sharply on a warm day instantly which brings a welcome relief! This can be the start of the waterfall walk and it brings an extra 25 mins to walk if you start from here. The area is stunning and car park again pay and display at Cwm Porth. It has loos and friendly staff there too. If you are in the area you have to visit if only to see the cave entrance. Just see the pics for scale it's huge.
reach here a bit late so that no anybody here. just walked inside a bit and take some picture then slightly walk around. slippery and some unknown place also one side full of water. dont take risk go further as a bit dangerous without guide i believe.
