Bayou Bend Collection and Gardens, the former estate of Houston philanthropist Ima Hogg, is located on the north bank of the bayou just east of Memorial Park. After passing under Shepherd Drive, the waterway enters Buffalo Bayou Park, which is bordered on the north by Memorial Drive and the south by Allen Parkway. The park continues for to Interstate 45, where it enters Downtown Houston. The bayou flows past Allen's Landing and joins White Oak Bayou before exiting the central business district at Interstate 69. The bayou widens considerably as it travels through the East End, culminating at the Houston Ship Channel.
