The Alton Towers Dungeon has moved to a staggered opening model, as it looks to increase users.
The scare attraction, which incurs an additional charge on top of theme park entry, now opens from 12:30 each day.
It has also begun to offers slots after Alton Towers’ official ride queue closing times on select dates.
Researchers from the TowersTimes website broke the news on Monday evening.
Costing between £9 and £11 per visit, the 45-minute Dungeon experience previously shadowed the park’s main opening times.
On days when Alton Towers closes between 16:00 or 17:00, the Dungeon will be available for shows starting 30 minutes after ride queues close.
The later openings are likely to be in response to low visitor numbers to the attraction, with after-park hours targeting those who do not wish to sacrifice ride time.
Opened in 2019, the Alton Towers Dungeon includes the latest incarnation of the boat ride system in the former Around the World in 80 Days, Toyland Tours and Charlie and the Chocolate Factory attractions.
Now known as the the Black River Boat Ride within the Dungeon, it is one of the UK’s oldest water rides, having first opened in 1981 as Around the World in 80 Days.
