This slate quarry isn’t only home to the world’s first cave trampoline, it also boasts the world’s longest zip line.  While the zip line is based above the surface only, guests can work out a little of their adrenaline on these trampolines after a long ride on the zip line above.  The line, named Zip World Titan, has been open on site for some time.  The proprietor was interested in adding a new attraction to the offering here in Blaenau Ffestiniog, Wales, and was inventive enough to think of placing a cave trampoline in the empty space below. The Cave Trampoline at the Zip World Titan site is open for business to those traveling in Wales and those lucky enough to live nearby.  It makes for quite an exciting outing, and leaves me to wonder one thing– what will these adventure entrepreneurs think of next?
