Diving in Cornwall

Cornwall offers a range of excellent dive sites for people with diving experience and for beginners taking there first plunge (first lessons)

The majority of Cornwall diving focuses on wrecks, marine life, and rock formations.

Some wrecks are shallow enough so that less experienced divers can enjoy them.

Since sailing around Cornwall is notoriously hard – there is an abundance of wrecks that are teeming with marine life.

Cornwall is renowned for its mild temperature and the sea temp is mild at around 16 degree C in June to 7 degree C in winter months.

Beware of strong currents particularly on the north coast – Newquay is known for strong waves.

Cornwall has one of the most under water landscapes in the UK.

The sea is clear, the Sealife is amazing, and the colours are a feast for the eyes.
