Check out some beautiful San Antonio history and visit the San Antonio Missions. There are four missions in the National Park. From north to south: Mission Concepción, Mission San José, Mission San Juan, and Mission Espada. Each mission is about 2.5 miles from the next mission. It is very easy to drive from mission to mission, and free parking is available at each mission site. There are also bike rentals along the trail and it is very walkable. Remember to bring water and sunscreen though, this Texas heat is intense!
