Work at Zip World Tower is well under way with hopes to open in 2021.
And now a rollercoaster has had approval from Rhondda Cynon Taf Council's planning department.
The one kilometre Coaster Kart will journey through the Tower site and the description says passengers will be "speeding along in a side-by-side kart as they dip and weave to stunning views of the Rhigos mountain range".
Two people will ride side side-by-side in the kart and the speed will be in the rider's hands and they will get two goes round the tracks with the ticket.
The coaster is pencilled in to open in March 2021, coronavirus restrictions dependent, and will be the first of its kind in Europe and potentially the world at that point.
Last week we brought you first look images from the Tower Colliery site and the developments thus far.

Photos from the construction site at the Rhigos shows the foundations for The Tower site being built, which will be home to a new zipwire dubbed Zip World Phoenix zip line.
The plans for Zip World adventure park include three zip wire courses, cabins and a car park.
Zip World has grown rapidly since launching its first super-fast zip line at Penrhyn Quarry in Bethesda in 2013.
