Description:
"Mt. Bonnell has served as a popular attraction since the 1830's. In the 1900’s, Austin businessman Frank M. Covert, Sr. donated the land Mount Bonnell sits on to Travis County. Fifteen years later, it was given to the City of Austin. The area at the top of Mount Bonnell was then referred to as Covert Park and, in the late 1930’s, a boulder monument was situated at the summit in honor of Covert. Today thousands of visitors ascend the 106 stone stairs to the summit to take in sweeping panoramic views of the lake, downtown, and the western hills of Austin."
