The former "Baywatch" babe finally returned home from Turkey last night ... where she sustained several injuries to her face and body after a nasty fall on Mt. Ararat ... where the ark is rumored to be hidden.
"I'm just glad to be home," Donna said ... adding, "I found a lot of information."
When asked if she was in fear for her life, Donna replied, "Yeah ... I was."
But she explained, "I've just always wanted to climb Mt. Ararat and search for Noah's Ark ... and I know everybody thinks it's funny and it's a big joke and people don't believe in it ... but I do ... and I've wanted to do it ever since I was a kid."
Donna said she wasn't just hunting for the Ark ... she was also hoping to find Donald Mackenzie ... a fellow Ark hunter who went missing during his trip to Ararat a few years ago.
While she didn't find Donald ... Donna claims she refuses to give up her search ... and vows to plan her return trip as soon as possible.
