Here's how BBC News reports it:
In 1980 American airmen from RAF Woodbridge witnessed mysterious lights.
The mystery over the sighting has continued ever since and the three-mile trail has been built to meet public interest. The trail opens on 18 August.
The UFO trail, which the Forestry Commission says is one of the first in the country, has received ?2,000 of funding from the Lottery's Award for All scheme.
To mark the opening, the Forestry Commission is staging two guided walks which will be led by a retired forester, Vince Thirkettle.
He will retell the intriguing tale of the supposed UFOs on the trek round and even visit where the sightings took place.
Brenda Butler, a local resident, said: "Rendlesham is a very strange place - it's like a doorway opening from another dimension."
Guided walks will take place on 18 and 25 August, starting out from the Rendlesham Forest Centre from 1700 BST.
