A couple on a romantic stroll were baffled when they stumbled upon an outdoor cannabis farm.
Shocked Oscar Lerin, 35, was out for a walk with his girlfriend when they strayed a few metres off the forest in search of mushrooms.
But they couldn't believe their eyes when they found themselves in the middle of a patch of around 70 professionally cultivated adult marijuana plants.
Oscar and his girlfriend, who has asked not to be named, snapped a few cheeky photographs crouched amongst the strong-smelling leaves before continuing with their walk.
Oscar, an engineer , from Essex, said: "It was funny. We couldn't believe it. We were like 'really? Is this real?'
"We never expected to see something like that in a public forest."
He continued: "We like nature and we went to the forest to have a walk and have a look at mushrooms and identify them.
"We were just walking and walking and I looked around and I thought this looks like marijuana plantation.
"The smell was really strong so I knew it could be nothing else.
"It was very close to the path and just near it really, behind a big bush.
"I think there was around 60 or 70 plants and it covered quite a large area - about 15 or 20 square metres.
"The soil was different. We had a look and there was a sheet of plastic on the ground and the different soil was on top and the plants were in there."
The couple made the wacky discovery on Saturday morning in a patch of woodland just metres from a school.
A spokeswoman for the government body said: "We can't comment at the moment as it's a police matter."
