A lake known as the Disappearing Tarn has delighted hikers and photographers on a mountain in Australia after filling with a rare volume of water.

The normally dry lake on Mt Wellington in Tasmania is not easily seen. It was once described by a local newspaper as part of state “bushwalking folklore”.

Heavy rain on Friday prompted it to swell with clear, blue-green water.

The site typically fills with water about once or twice a year following rain or snow, locals say.

“The pictures I’ve seen in the last two days show it at the fullest I’ve ever seen it,” Wellington Park ranger Ben Masterman told the BBC.

“It’s not a filter – it’s actually that colour – that remarkable blue that becomes more intense and sapphire and more mesmerising the deeper the water gets.”

He said that the lake forms in a “boulder field” about halfway up the 1,271m (4,200ft) mountain.

Irish photographer James Spencer trekked to the region on Saturday.

“It was about the size of a swimming pool when we were there – and a good 3-4 feet deep,” he said.

“I was fairly certain it was going to be there, but it’s never there all year round, so you sort of have to know where you’re going.”

About 30 other people were there at the time, he added.

Other visitors have also posted pictures of the lake on social media in recent days.

Mr Masterman warned visitors to carry adequate supplies when visiting the site. He said the lake was likely to run dry again soon.
