Here's a look at how Joe Montana lives ... and if ya got $30 MILLION lyin' around -- you can live like one of the best quarterbacks EVER too!!!
The San Francisco 49ers legend's EPIC 500-acre palace in Calistoga, California is up for sale ... and the place is ridiculously awesome.
The main house is a 9,700-square-foot mansion that features 3 bedrooms, 3.5 bathrooms and insane wine cellar that can hold 3,500 bottles of booze.
Outside the main place -- there's a horse-riding area, a basketball court and a bunch of olive trees that produce anywhere from 30-60 GALLONS of olive oil every year!
