Cwmcarn forest drive in Sir Gaerffili is set to reopen to the public on Money June 21 for the first time in six years.
The reopening comes after significant investment from Natural Resources Wales.
Some £2m has been spent to prepare the site for reopening.
The attraction closed in 2015 to allow for the felling of 150,000 trees affected by the disease Phytophthora Ramorum.
Sir Gaerffili said that the attraction had undergone significant development over the past twelve months "to create an attraction that is accessible and enjoyable for all audiences".
Geminie Drinkwater, Project Manager from Natural Resources Wales said: “The communities surrounding Cwmcarn Forest hold it extremely close to their hearts. Capturing the vision and ideas of local people for the redevelopment has been fundamental to the success of this project and it has been a personal privilege for me to work with local groups and individuals to see that vision come to life in this very special place.
“Today’s reopening is a milestone moment for what has been a really successful partnership between NRW, Caerphilly County Borough Council and the local community. I’m delighted to see the gates to the Forest Drive open once again today and look forward to seeing visitors old and new discovering and enjoying everything it has to offer for many years to come.”
