Parents have always admired the smart, sleek designs from Denmark, and children have always loved the Legos this kid-friendly country produces. The combination makes a vacation to Denmark one of the best options for families heading to Europe. Copenhagen is well worth settling in for a few days, as younger children enjoy playing in its lovely parks and castle grounds. Older children will appreciate zipping around on bikes and sampling exotic food in the markets, just like the locals. And be sure to get out in Denmark’s relaxing countryside, especially during the wonderful summer weather. Kid-friendly hotels range from contemporary properties with distinct Danish decor to regal, historic accommodations.
