Hovenweep National Monument is located in both Colorado and Utah and is known for its unique and well-preserved Ancestral Puebloan ruins. Some good reasons to visit include the opportunity to explore ancient structures, learn about the history and culture of the Ancestral Puebloans, and to take in the stunning views of the surrounding landscape. Specific points of interest to see include the Square Tower Group, the Hovenweep Castle, and the Cutthroat Castle. One interesting fact about the area is that the structures were built between 1200 and 1300 AD and contain a mix of architectural styles from both the Puebloans and their neighboring cultures. The best time of year to visit is in the spring and fall when temperatures are mild and the crowds are smaller.
