They hurried on from the castle as the clouds started to gather, and they were soon at their holiday cottage, settling in.
The weather hadn't been very promising when they set off, but it did improve as the days went by. Anglesey is only a short distance away from mainland Wales where the high mountains of Snowdonia are. They could see the mountains from the cottage they were staying in and, after a particularly cold and wet evening at the cottage, they woke up the next morning to see that the mountains were all covered in snow!
"Gosh!" exclaimed Edward. "Look at all that snow! And yet the fields around here are all still green and there's no snow anywhere! How does that happen?"
"It's because the mountains are so high up," explained Scary. "The higher up you are, the colder it gets and the more likely it is that rain in the area will fall as snow."
