The tribe owns two tourist attractions here: Billie Swamp Safari, and Big Cypress Entertainment Complex.
The American rock band Phish held their millennium concert at the reservation from December 30, 1999 to January 1, 2000. With 85,000 people in attendance, it was the earliest and largest sold-out millennium concert. Phish performed three sets of music on the 30th, an afternoon set on the 31st, and an unprecedented "Midnight To Dawn" set, which ran from 11:50pm until sunrise on January 1, 2000.
The entertainment complex is surrounded by 350 acres for outdoor events, in addition to a newly renovated rodeo arena with seating for 3,000 people. Stables have stalls for 86 horses.
The tribe constructed the Ah-Tah-Thi-Ki Seminole Indian Museum, which opened in 1997. In 2005 it was the first tribal museum to receive accreditation from the American Association of Museums (AAM), and is a Smithsonian Institution Affiliate.
