"I'll never forget the look on little kids' faces when they see the place."
New Fantasy Cave president John Hart said Mr Edwards had put in 120 per cent at the cave.
"Nothing was too much effort for him, he has left a bloody big legacy," he said.
"I've stepped into some very big shoes. Ces fought hard to keep the cave open in 2011 when the lease of the building changed hands and he really brought it back to what it is today, our top tourist attraction.
"The Fantasy Cave was Ces' life and he thoroughly enjoyed every day there."
Mr Edwards also had a long 46-year association with the Dannevirke Lions Club, was previously a volunteer with the community night patrol and managed Dannevirke High School cricket teams.
A funeral service for Mr Edwards will be held at St John's Anglican Church Dannevirke at 1pm on Thursday.
