The actor, who plays Sawyer, explained that filming the end of the series was physically draining.
"The end of shooting was tough," he told Zap2It. "It was a sprint to the finish, it was a huge script, a lot of being wet, so we were tired.
"But, you know, having a blast too, because that's become a family to us - the crew and the cast and everyone - so we really had some amazing camaraderie and special moments those last days of shooting. It was awesome."
Holloway also revealed that he is excited about watching the series finale when it airs later this month.
"I think it's going to be phenomenal," he said. "I can't wait to see it."
The series finale of Lost will be broadcast on May 23 at 9pm on ABC in the US and on May 28 at 9pm on Sky1 in the UK.
