Canolfan Hamdden Arfon

Swimming pools, sports halls, and fitness facilities might not sound like holiday material, but when the weather turns in North Wales, this leisure centre near Caernarfon becomes a proper lifesaver. The modern complex offers indoor swimming, courts for various sports, and gym facilities that'll keep active families entertained when Snowdonia's peaks disappear into the clouds.

Families staying at nearby parks like Glan Gwna Holiday Park or Coed Helen Holiday Park will find it handy on those inevitable rainy days. The swimming pool is the main draw - decent sized with separate areas for serious swimmers and splashing about with the kids. Sports enthusiasts can book courts for badminton, football, or basketball, though you'll need to call ahead to check availability.

It's not going to be the highlight of your Welsh adventure, but it serves its purpose well. The facilities are clean and well-maintained, staff are helpful, and it's reasonably priced for what you get. Allow a couple of hours if you're planning a swim and some court time.

Location-wise, you're perfectly placed between the medieval walls of Caernarfon and the dramatic scenery of Anglesey. After working up a sweat here, the castle and waterfront are just minutes away for a proper Welsh day out.
