Reserve a sunny, cool afternoon to traverse the eight-mile San Antonio Mission Reach stretch of the San Antonio River just south of downtown and the Alamo. The hike and bike trail and river improvements are all part of a multimillion dollar investment by the city and other partners to encourage outdoor play in and around San Antonio's most historic sites. Grab your bike or canoe and snake along this revitalized part of the San Antonio River, which connects four historic missions that flourished in the 1700s during Spanish exploration. Along the way you'll find informational plaques that tell the story of each mission, as well as picnic tables and benches for you to enjoy a snack or lunch during your excursion.
