They apparently made their way down a steep hill to the beach a long way in from the road itself but can't get back up.
After a few hours, Police finally got in contact by cellphone with them and the three told them they were safe. The fire department brought in its argo along with a four wheel drive truck which can make their way along the trails which are described as pretty rugged.
The Coast Guard put out an all points bulletin and the three were picked up from the beach by a zodiac.
