Harrison's Entrance Gwaenysgor Cave

You'll find Harrison's Entrance tucked into the hillside near Gwaenysgor, a proper limestone cave that demands a bit of scrambling to reach but rewards you with something genuinely atmospheric. The entrance itself is modest - easy to walk past if you're not paying attention - but step through and you're inside a natural chamber that feels properly remote despite being only a few miles from Rhyl's caravan parks.

It's the kind of place that appeals to geology types and families wanting something more adventurous than a standard beach day. The cave itself is small enough that you won't spend hours inside, but the walk to get there and the satisfaction of finding it yourself makes the trip worthwhile. You'll need decent footwear and probably a torch - bring a proper one, not just your phone's light.

There's no charge to visit, and no facilities to speak of, so come prepared. The real value here is the escape from the holiday park routine. Golden Sands, just down the road, makes a sensible base if you're caravan camping in the area.

Go when the weather's settled. A wet day makes the approach slippery and the cave loses its appeal when you're drenched. Spring or early autumn work well. Allow a couple of hours including the walk and a proper look around - it's not a tick-box job. Honest assessment: it won't blow your mind if you're expecting something enormous, but it's a solid half-day adventure that beats another hour on the promenade.
