Penguin Coast

The name's a bit of a misnomer - you won't find actual penguins at Penguin Coast near Kilgetty, but what you do get is a proper freshwater lake surrounded by woodland that's genuinely worth an afternoon. The water's the main draw here, clear and peaceful, with good walking paths running along the shoreline that give you decent views across the lake. On a calm day it's properly lovely. The woodland around it means you're shaded from the worst of the sun, which is welcome on warmer days. Most people allow a couple of hours to walk the perimeter at a leisurely pace, though you can knock it out quicker if you're just after a short stroll.

It's ideal for families with younger kids who want a lake walk without the crowds you'd get at somewhere more famous. Dog walkers absolutely love it - plenty of space for them to run about, and the paths are wide enough that you're not constantly dodging buggies. If you're serious about birdwatching, bring binoculars; the woodland attracts various species, though it's not a specialist site.

Being just outside Kilgetty puts you within easy reach of several nearby holiday parks - Swallow Tree Gardens, Florence Springs, and Haven Kiln Park are all within five miles or so, making this a decent half-day activity if you're based in the area for a week. Entry appears to be free, which is refreshing. Go early morning or late afternoon if you want it quiet; midday can get a bit busier with school groups.
