King William Paddling Trail

Access Information

The launch point is also the take-out point found near the San Antonio River Authority’s Main Office at 100 E. Guenther St. via a concrete boat ramp. This is one of only two areas in which stand-up paddle boarding is allowed on the San Antonio River in San Antonio.

Discovery Information

The King William Paddling Trail is the place to enjoy a serene paddle on the river and explore history, art, bridges, and good eats and drinks all in the same afternoon. What appeals to many paddlers is the smooth waters and the easy-to-access launch area. Explore a Monarch Butterfly Way Station while you launch your vessel and experience the diverse range of wonderful wildlife, from hawks to turtles, co-existing with historic and modern buildings. Take as long as you like on your paddling adventure, and then be sure to check out the food and art scene in the King William, Blue Star, and Southtown areas when you finish.
