We’re all fascinated by a good mystery. Whether it’s looking for Bigfoot, the Loch Ness Monster, bizarre conspiracy theories, tales of UFOs and aliens or our obsession with ghosts, you can’t beat a good mystery series on TV!

Mysteries and the paranormal have their fair share of sceptics but watching these mystery documentaries may just convince one or two to believe otherwise!

What lurks under, above or beyond? Here are some of the best mystery TV series on the Discovery Channel.

Is Anybody Out There…?

What better way to start than with the hunt for ET. Humans have been fascinated with the possibility of extraterrestrial life for hundreds – if not thousands – of years and the best unsolved mystery TV shows have the remarkable ability to make us question what we think we know…

With aliens on the mind, then there’s a host of amazing UFO documentaries to consider. In Uncovering Aliens four professional paranormal investigators see if they can get to the bottom of a huge uptick in UFO sightings, while Aliens: The Definitive Guide explores what would happen if we did encounter lifeforms from another world.

Or perhaps aliens already walk among us? UFOs: The Lost Evidence suggests they might already be here, thanks to eye-witness stories and declassified government documents. Then there’s one of the most famous alien proponents of modern times, speaking out in Bob Lazar: Area 51 & Flying Saucers.

Surely it’s not a monster? Some of the most famous and most enduring mysteries focus on monsters and on discovery+ we have some utterly fascinating unexplained mystery TV shows focusing on these legendary beasts.

Has new Nessie evidence come to light? Professor Neil Gemmell investigates in Loch Ness Monster: New Evidence. Another equally famous but so far elusive monster is Bigfoot, but can an elite team locate it for the first time? Watch Expedition Bigfoot to find out.

From deep inland to the deep blue sea. Ocean divers hunt for sea monsters around the British Isles in Monsters of the Abyss, while in one of the most earth-shattering unsolved mystery documentaries of modern times, marine biologist Dr. Paul Robertson claims the existence of one of the most intriguing creatures of all in Mermaids: The New Evidence.

Unexplained mystery TV shows are all the rage and you can have your pick of the perplexingly paranormal with this fantastically frightening fare.

The paranormal investigators in Kindred Spirits try to identify apparitions that ‘live’ in people’s homes. Equally enthralling, after buying a Demon House, paranormal pro Zak Bagans begins to understand what spooky goings-on he and his team have let themselves in for. This one is not for the faint-hearted!

One of the best mysteries shows on the Discovery Channel has to be Most Terrifying Places. We all know about old or abandoned buildings but this takes it to the next petrifying level! Hear spine-chilling accounts of some of the world’s scariest places that will definitely keep you up at night, but that’s nothing compared to our next show…

Can you imagine being confined in some of the most genuinely terrifying places in the world for three straight days. No, nor can we, but paranormal A-listers Nick Groff and Katrina Weidman do just that in Paranormal Lockdown. If paranormal is your thing, this is a ‘must watch!’

It’s Black Sabbath every day in the Osborne household but no more so than when Ozzie’s offspring Jack and paranormal investigator Katrina Weidman search for Portals To Hell, the sinister places in America rumoured to be doorways to the underworld. Just one of the unexplained mystery TV shows that you can catch exclusively on discovery+.

We’ve also got our own real-life ghostbusters on discovery+. Some of the best mystery TV series are about ghosts, including Alaska Haunting which tells scary tales of hauntings in the last frontier, frigid and isolated, miles from anything or anyone…

If you’re looking for the best ghost and mystery documentaries on TV, look no further.

Best buddies Dalen Spratt, Juwan Mass and Marcus Harvey – better known as The Ghost Brothers – battle it out with Dakota Laden, his sister Chelsea and friends Tanner Wiseman and Alex Schroeder of Destination Fear fame to see who can find the most haunted places in America.

One of the most popular spookfests on the Discovery Channel is Ghost Adventures presented by glutton for ghoulish punishment Zak Bagans. Zak and his team of intrepid investigators scour the USA to understand why and how supposed haunted locations got their reputations.
