Take I-515/US 93/US 95 south out of Las Vegas approximately 18 miles into Boulder City (this route simply becomes US 93 South). Once in Boulder City continue straight through the intersection that takes US 93 to the left towards Hoover Dam on Nevada Highway. Go through town until Park Street and make a sharp right turn. Park Street is identified as nearly the top of the hill and one will pass a large turbine wheel from Hoover Dam in a park. Follow Park Street about .3 mile, bearing to the left as it makes a "Y" and drive into the Retreat Center’s parking lot.
