Sunday was the park's last day in 2017.
The park in Gray is host to more than 30 species native to Maine. Many of the animals living in the park cannot survive in the wild.
Officials said it's been a great year and they want to thank every one who came out to support their work.
Park superintendent Curt Johnson stated "It was a fantastic year for us, we have another year with our attendance. We had over 125,000 people this year. And the reason it went so well was those peak season months. July and August we had over 56,000 people here."
The park is home to black bears, bald eagles and moose.
"Byron the Moose" got a little curious about our camera man, so he came up and said hello. Byron even granted fans with a few selfies.
The park re-opens in April 2018.
