Sylvester Stallone and his beautiful family were soaking up the sun in Baja California ... hitting another vacation hot spot during the Summer of Sly.
Sly and his daughter, Sistine, kicked off their Mexican beach vacay with a dip in the hot tub and some sunbathing in Cabo San Lucas. That's 20-year-old Sistine in the white bikini. As they say south of the border -- que linda!
The Stallones have been stamping their passports this summer ... looking hot on a yacht in the French Riviera.
