Although they are separate parks and vary greatly in size, Warren and Wells are next-door neighbors and have similar uses. Warren is a 96-acre nature area and borders Felker Park on the east (north of Shunganunga Creek). It includes a section of the Shunga Trail, a pond and a tree nursery used by Parks and Recreation of Topeka. It can be accessed from Felker, Big Shunga Park (on the east) or the Kansas Neurological Institute (on the north), and is a great place for birdwatching. Wells is south of Felker, Warren and the creek (but north of the car wash). It's about five acres in size and consists of a nature trail.
