Fresno is the largest city in the San Joaquin Valley, a farm city with a historic theater district and gardens. The Tower District, named for the Tower Theatre, mixes vintage shops, restaurants, and live venues, Forestiere Underground Gardens offers a network of underground rooms and gardens built by hand, and the Fresno Chaffee Zoo draws families to Roeding Park. The Fresno Art Museum shows modern and contemporary work, Woodward Park offers lakes and trails in north Fresno, and the San Joaquin River gives the valley a green corridor.
