Name your favorite sport and you'll probably find it at Camp Sienna. There are fields for baseball, softball, soccer and multi-use, as well as courts for sand volleyball and basketball. Youth sports leagues for soccer, lacrosse, gridiron football, baseball, flag football and softball utilize two concession stands during games. Adult leagues for soccer and softball also play at Camp Sienna. Beyond organized sports, residents can walk along 1.5 miles of trails to an overlook of the Brazos River, picnic at the pavilion or entertain the kids at the Camp Sienna playground. The park also is host to the popular Halloween Fall Family Camp Out, a sell-out event that draws hundreds of Sienna residents each year.
