The San Antonio River Walk is both a major visitor attraction and a great place to run. In the early 20th century, a flood along the San Antonio River caused massive damage to the area. In the years that followed, efforts were made to prevent the flooding including the construction of the Olmos Dam and a bypass channel. Over time, the River Walk was constructed, revitalizing the San Antonio downtown area. Today, the River Walk is a major attraction, with many historical sites located along the route, plus a festive scene of boat tours, bars, restaurants, and hotels. RIVER WALK INFO

Overall, the River Walk is about 15 miles, between the San Antonio Zoo to the north and the Mission Espada/I-410 in the south. It’s paved the entire way. There are three distinct sections: downtown loop in the Alamo area; River Walk North/Museum Reach; and the South (Mission Reach) section, which passes several parks and 18-century missions.  The path is mainly paved, there are mile markers, and there are many parts that have trails on both sides of the river. There are some tributary trails coming off the River Walk, and a couple of on-road sections. This TRAIL MAP shows all the trail sections and the key sites along the way. From downtown/Alamo area, the path extends ~4.5 miles north and ~10 miles south. We’ve created two route maps: Downtown loop & South; and from Downtown North. 

Downtown Loop (1-1.5 miles)

There’s also a 1 mile loop section of the River Walk in downtown San Antonio that comes off the main north-south flow of the San Antonio River. This is the most ‘touristy’ area. See the Alamo, Tower of the Americas, Convention Center, Briscoe Western Art Museum, & San Fernano Cathedral. The path is mainly below the road grade. 

North Section (~5 miles)

From Alamo Plaza, the north section, known as the River Walk Expansion/Museum Reach. Running north and mostly below the road grade in the sections closest to downtown, the route will take you past Hugman Dam, Alamo Mills Dam, the San Antonio Museum of Art, and across the convergence of the many metroways crossing the city. The northern 2 miles is in the area of Brackenridge Park, where there are some additional trails. There’s an on-road section along Avenue B, skirting the edge of Brackenridge Golf Course. 

South Section & Mission Reach Trails (~10 miles)

This south section of the River Walk extends for 10 miles from downtown to San Antonio Missions Natural Historical Park. The first ~4 miles are pleasantly green. South of I-10, the trail becomes more open & prairie-like, passing several parks and 18th-century missions. There are numerous additional trails in the Mission Reach section. Key sites, landmarks along the way, from our route map:
