Historic Downtown Littleton. Another area of Denver that offers a glimpse into the relaxed ambience of a different era, downtown Littleton offers a charming Main Street lined with turn-of-the-century buildings that house some of the metro area’s most unique, independently owned businesses. There are 11 art galleries, 14 specialty gift shops, and six clothing boutiques. You can experience the town’s historic agricultural roots at the Littleton Historical Museum, where you’ll find two working farms, one from the 1860s and another from the 1920s, complete with chickens, pigs, oxen, cattle, and horses, making it an educational and fun family outing. Hudson Gardens is another attraction, featuring a multitude of plants, flowers, trees, ponds, wildlife, a garden railroad, and a beautiful outdoor setting along a mile-and-a-quarter walking path.
