Zilker Park is a 361-acre park nestled in the heart of downtown, right off Lady Bird Lake. The park was founded in 1917 and is home to picnic facilities, bike/canoe rentals, a disc golf course, a large playground for children, the Zilker Zephyr train and Barton Springs Pool, an urban oasis where swimmers plunge into 68-degree, spring-fed waters. The park is also the host to great events like the Austin City Limits Music Festival and the Trail of Lights.
