El Presidio Park functions as home to the annual Tucson Folk Festival event, which is held each year at the beginning of May. Activities of the weekend celebration include dozens of local and national musical artist performances in conjunction with the sale of various works of craftsmanship and a delicious assortment of fine cuisine.

Unlike many eastern cities in the United States, Tucson was based around a grid plan, with one area planned to be the geographic center. While the geographic center has shifted as the city has grown, the streets help to set the borders between neighborhoods and make the town easier to navigate.
