There's something eerie about this Brazilian forest

At first glance, there's nothing too out of the ordinary about this footage of a forest in Brazil. But upon closer inspection, it's clear something's not quite right.

The clip, posted to Brazilian tour company Recanto Ecológico Rio da Prata's YouTube page, was taken in early February on the breathtaking Rio de Prata trail, and shows a portion of the track seemingly trapped in a space-like vacuum.

Nothing moves, and the jungle has an eerily misty glow about it that's almost alien in its beauty.

But those with a keen eye will note the top of the frame betrays the truth about this patch of jungle.

With remarkably still and clear conditions, there's very little to give away the fact that this stunning video is in fact taken eight-feet under water.

The original YouTube clip of the underwater forest, titled ' Submerged Trail in the Rio Prata Ecological Recto' in its English translation, was uploaded to YouTube earlier this week and has already garnered more than 800,000 views, drawing people in with its raw and mysterious splendour.

Captions posted with the video explain that the footage was taken on a tour after heavy rainfall, submerging this portion of the trail entirely.

"Despite the flood, on the day the video was recorded the waters of the Olho D'Agua river remained crystal clear due to their conserved riparian forest and being inside a Private Reserve of the Natural Patrimony - PRNP, a type of Conservation Unit."

The caption goes on to state that by the day's end, the water had returned to its normal level, and that the flooding was a rare occurrence.

Some YouTubers were quick to note the clip's spooky factor.

"That's how horror movies get started," one viewer said.

"How dare you not show what it looks like above water," another writes.

While others have criticised the clip for not being long enough, with the filmmaker stopping of the bridge.

"Need much longer video.. thats incredible. [sic]"

The tour company also offers fresh water diving in the region, and judging by that inviting crystal-clear water, we'd say you're in for some prime underwater viewing.
