Rebild National Park is located in an area of Northern Jutland known as the Himmerland and, while it's probably best recognized for its annual 4th of July celebration (the largest of its kind outside of the U.S.), this is hardly a place reserved for nostalgic expats in need of yearly fireworks. Known for its forested valleys, heaths and natural springs, there are a wide variety of options available for anyone interested in exploring the great Danish outdoors here. Hiking and mountain biking are two particular favorites, with an abundance of well maintained trails that range from gentle to strenuous, but you can also get out on horseback, on kayak (along the gentle but scenic Lindborg) and, come winter, on cross country skis. There's even an available ropes course and campsite. Check out the official site for more info (Danish only, unless you're a master of Google translate) and enjoy the lesser-touted side of this quality national park.
