San Antonio Missions National Historic Park sits in the city of San Antonio, Texas, but the park doesn’t include the famous Alamo. The four missions — churches built by early Spanish settlers — that are part of the park were built in the late 1600s and early 1700s. Originally constructed as part of Spain's colonial expansion in the Southwest, they retain the distinct architecture of their era and have been well preserved over the years. Not only is this a historically significant park, it is also a great place to hike and bike. A paved 8-mile trail passes through the countryside, and people can follow the trail to each mission.
