Ogof Filast

Wild adventure awaits those willing to scramble down the clifftop path to reach this sea cave near Cardigan. Ogof Filast sits tucked beneath the dramatic coastline, accessible only at low tide when the waters retreat far enough to reveal the entrance.

Getting there requires a bit of determination - the coastal path isn't clearly marked and you'll need to time your visit carefully with the tide tables. Once inside, the cave extends back into the cliff face, though how far depends on recent weather and sea conditions. It's properly wild, with none of the handrails or lighting you'd find at commercial caves.

This one's definitely for the adventurous types rather than families with small children. The scramble down can be treacherous when wet, and you absolutely must check tide times before setting off. Local knowledge helps - ask at Cardigan before heading out.

Spend half a day here if you're combining it with a proper coastal walk. The surrounding clifftops offer cracking views across Cardigan Bay, making the effort worthwhile even if the cave itself proves inaccessible on your visit.

With camping options like Mwnt Camping and Nantycroy campsite within walking distance, it works well as part of a longer stay exploring this wilder stretch of the Pembrokeshire coast. Just don't expect creature comforts - this is raw Welsh coastline at its most uncompromising.
