This is the breathtaking moment tourists descended a steep spiral staircase to reach a spectacular hidden viewpoint inside a cave.

Holidaymaker Jane Anda carefully made her way down the dizzying metal steps of Pukaway Cave on Coron Island, Palawan, the Philippines, on September 9.

Point-of-view footage shows Jane making her way down the staircase before stepping onto a floating bamboo raft, with crystal-clear waters glistening below.

Inside, a blue light illuminated the cavern, casting a glow across the rugged rock walls.

Jane said: 'I did a little trekking along a steep trail before taking a steel staircase through a narrow path in the rock wall.

'Inside, there is clear and cold brackish water and coloured lights to highlight the rock formations. You can even freedive here to see the stalagmites below.'
