Plas y Sarn Canolfan Hamdden

The leisure centre in Trimsaran sits a few miles inland from Burry Port, serving the local community with a straightforward mix of swimming and sports facilities. It's a proper working-class venue - nothing fancy, but functional and well-maintained. You've got an indoor pool, a gym, and various sports halls that host everything from badminton clubs to school PE lessons.

If you're staying at one of the nearby caravan parks - Shoreline, Gwlad Glamping, or Parkdean Resorts Carmarthen Bay - this is handy for a rainy afternoon or to tire the kids out. The pool is the main draw for families. Weekend hours are tight (10:00-15:00 Saturday and Sunday), so plan accordingly if that's when you're visiting. Weekday sessions run much later, which suits people staying longer.

It's not a destination in itself, mind you. You wouldn't drive here specifically for a swim - there are leisure centres like this all over Wales. But if you're based at one of the holiday parks and the weather turns grim, it beats sitting in the caravan. The Carmarthen Bay area has Pembrey Country Park itself just down the road for proper outdoor time, so you've got decent options either way. Expect to pay an entrance fee, though exact prices vary depending on what you're using. The staff are friendly enough, and it does what it says on the tin.
