TMZ has obtained a photo of Tiger Woods back in the danger zone -- the Las Vegas pool party scene -- where he was SURROUNDED by hot chicks in bikinis ... and a TON of security.
Woods quietly hit the Liquid pool party at the Aria Hotel on Saturday ... sporting a t-shirt, shades ... and a ringless wedding finger.
Sources at the pool tell us Tiger was flanked by a security team -- like the behemoth on the far right -- while he visited with a couple of friends inside a private cabana.
Of course, Vegas was the epicenter of Tiger's adultery back in the day -- thanks to ladies like Rachel Uchitel and other women of her ilk.
This time, it's unclear if Tiger found a special friend at the pool party ... but he definitely had some options. Check out the pics from the pool that day ... thanks to our pals at SpyOnVegas.com.
