Underground wonderland

Adventure seekers burning off energy on a giant "trampoline", suspended in a huge cavern near the mining town of Blaenau Ffestiniog, northern Wales, earlier this week.

Hidden underground in a 176-year-old disused slate mine, the Bounce Below adventure park boasts a network of giant trampolines, walkways and slides.

The trampoline-like nets are hung within two vast chambers at different levels, with the highest reaching 56m from the bottom of the cavern. It takes about an hour for visitors to jump, bounce, slide and climb their way through the subterranean playground.

The Bounce Below park, which calls itself "the first facility of its kind in the world", is housed in the same mines that are home to Zip World Caverns, the world's largest fully underground zipline and adventure course.
