Winter in Colorado is beautiful but is sometimes best seen from indoors–especially when the temperature drops below freezing and the yard is buried under a foot of snow. But kids tend to get bored quickly at home, making it nearly impossible to spend every snow day cooped up in the house. Luckily, Denver has many options for indoor play areas.
