In 1978, Stoney Cove Marine Trials Ltd was formed to develop the full potential of Stoney Cove for scuba diving and commercial underwater activities. Since then there has been a continuous programme of improvements which began with a tarmac surface for the waterside parking area. A shower facility and that most important item, a pub, followed soon after. September 1999 saw the completion of a new access road and entrance to Stoney Cove. Beneath the new road is a drain system that directs rainwater and silts from the cliffs and banks away from Stoney Cove during storms. This has significantly improved underwater visibility during rainy periods.But that's not all brought to Stoney Cove in year 2000 The Stanegarth, the U.K.'s largest inland ship wreck, and the Nautilus submarine have both provided major new attractions.
