It will close on October 15th this year which is about 6 weeks earlier than normal.
It's closing so volunteers can get to work replacing some of the boardwalks sections which have become weathered over the years.
Director Jim Bird said "They'll be taking out 48 old sections and replacing them with composite decking which will last much longer."
Jim said they welcomed 23,000 visitors this year.
Supporters have helped raise thousands of dollars to replace 300 sections of the boardwalk, but they still need to find money to replace the remaining 209 sections.
