A trip to Holt Hall used to be the highlight of every Norfolk school child's year, with activities such as raft building, orienteering and outdoor cooking.
But now the hall is for sale after two years of uncertainty around its future.
Before it closed it was the second-largest provider of outdoor learning residential stays and learning day visits in Norfolk.
In 2019 more than 50 schools took trips to Holt Hall.
The decision to close it in December last year was highly controversial with critics claiming the decision was short-sighted and would leave children as the greatest losers.
Holt Hall went on the market on October 26 and is a Grade II-listed Victorian mansion set across 86 acres.
