Wales is a fabled land, jewelled with mighty castles, mountain ranges, unspoilt beaches, deep countryside, rugby, industry, poetry and song.

The great outdoors draws in extreme sports fans from across the world; those of you that lead a healthy life-style may pick Wales as a wonderful place to introduce your kids to trekking, cycling, climbing, kayaking and that’s just for starters. Even the best laid plans can come undone because of Mother Nature from time to time. When the weather just isn’t cooperating, you’ll find yourself asking what to do in Wales when it rains.

So where do you go when the weather puts the ‘mockers’ on your day? Well, the simple answer is, “Don’t let it!” Here’s a list of things to do in Wales in the rain; some are indoor activities, and some are outdoors where the rain showers just add to the fun.

For easy reference, we’ve split our rainy-day activities in Wales into two sections: things to do in North and South Wales on a rainy day.

Things to do in North Wales on a rainy day

The landscapes of North Wales suit an outdoor lifestyle, but when the heavens open, there’s still plenty to keep you occupied and active.

If you love a challenge and want to get your hands dirty, the caverns are a great choice on a bad weather day (or any time really).

This experience is at the same location as Zip World and it combines the experience of being underground with the unbridled joy of leaping up and down on a trampoline, just like at Jump Jam (above).
