The Welsh veteran travelled to Turkey with Manchester United in 1993 for a Champions League clash with Gala and ahead of Wednesday's group stage opener, admits it was a very intimidating environment for a young man to walk into.
"I remember it vividly. It will always stick with me," Giggs said.
"I was 19 and, when we arrived at the airport, there were all the banners and fans. Thousands of fans screaming at you.
"There were things being thrown at us when we were driving away on the coach. Outside the hotel their fans were chanting all night, making sure we didn't get any sleep. People were phoning the hotel room."
And Giggs said the aftermath was even worse as United, who had Eric Cantona sent off, were knocked out of the competition.
"When we came off the pitch, it was chaos," Giggs added.
"Eric had already been sent off and the way back to the dressing room was underneath the pitch.
"There were armed police either side - not the kind of people you would ever mess with. They had helmets, batons, were all ready. And it just kicked off.
"I was just trying to get back to the safety of the dressing room as quickly as possible.
"Obviously not at the time because we lost and went out, but it was a great experience for us.
"They were a good team then and they will be a good team now."
