Llys y Frân Country Park & Reservoir

The reservoir itself is the main draw here - a proper water feature that cuts through moorland just south of Haverfordwest, and it's the kind of place where you actually feel you've left the coast behind. Walk the perimeter and you'll spot herons, the odd buzzard if you're lucky, and water that shifts colour depending on the light. It's genuinely peaceful, which is rarer than you'd think in Pembrokeshire.

Llys y Frân works best for walkers who aren't after anything too strenuous. The paths are manageable, mostly flat around the water's edge, and there's enough distance to make it feel like a proper outing without your legs complaining afterwards. Birdwatchers will spend hours here. Families with kids will get a decent couple of hours out of it - there's something satisfying about spotting wildlife and the water keeps children engaged longer than you'd expect.

It's free to visit, which helps. The nearest towns like Haverfordwest give you somewhere to grab lunch before or after, and if you're based at one of the local camping spots - Quarry Park or Llandissilio are both highly rated and within five miles - this is an easy morning or afternoon slot that breaks up a holiday nicely without demanding a full day commitment. Go early if you want the best light for photographs and the quietest stretch of path. The weather can turn quickly out here, so pack layers even if it looks settled.
