A drone was used to locate the boy halfway down precarious cliffs at Soldiers Bay.
Guernsey Fire staff, the cliff rescue unit, police, coastguard and the inshore lifeboat were called to the area just south of St Peter Port at around 5.20pm on Saturday (28 March).
A drone was used to to help locate the teenage boy and a get a rope to him.
He was helped down the cliff, which in this area is unstable, but was uninjured.
He was taken to St Peter Port by the RNLI's inshore lifeboat.
The rescue took more than an hour and a half.
Separately, a Police enquiry continues after fire ripped through a deserted cottage between the Occupation Museum and the Manor Hotel in the Forest parish on Saturday, with crews and volunteers still damping it down yesterday.
It is the second fire in an abandoned building in Guernsey within days but there is no suggestion that they are linked.
