However, 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.
