An enormous bungee jump platform has been set up near the I'm A Celebrity site in north Wales.
Viewers of the ITV show hosted by Ant and Dec have been given a glimpse of the contestants' first terrifying challenge which could involve launching themselves from a height.
The structure has been erected at the remote Alexandra Quarry near Penyffridd just outside of Caernarfon.

On Thursday workmen were seen in high-vis jackets on the site preparing for the launch show on November 21.
The first show in the series always features a daring challenge and in previous years contestants have jumped out of helicopters and abseiled down sheer cliff edges.
I'm A Celebrity has been contacted by MailOnline for further comment.
Woah! Viewers of the ITV show hosted by Ant and Dec have been given a glimpse of the contestants' first terrifying challenge which could involve launching themselves from a height
It comes after some of the celebs were spotted moving into cottages in Angelsey near Gwrych Castle, the ITV show's location for the second year running, over the weekend.
The stars have been treated to luxury holiday homes which boast vaulted ceilings and weather-proof windows and sliding doors which frame idyllic views.
Producers are going to create a bubble for the famous faces which will attempt to avoid rows over vaccinations and keep them safe once in quarantine.

A show spokesperson previously told MailOnline: 'Like last year, our celebrities will do a two week quarantine with regular testing prior to entering the castle, and will then form a bubble for the duration of their time on the show.'
Last year, I'm A Celebrity required the celebrities to wear proximity monitors which flashed and buzzed when they came too close to one another.
Bosses also scaled down the production team, and had cameras set up already on-site so cameramen didn't have to be on the set.

Hosts Ant and Dec are set to welcome the new batch of stars to the site in a number of days, with the show taking place in Wales rather than Australia for the second year running in light of the pandemic.
Renovations at Gwrych Castle are nearing completion ahead of the new series kicking off later this month.
Two towers were seen being constructed on the grounds of the castle in North Wales on Saturday.
The towers, which had eight pointed sides, were surrounded by scaffolding.
