The influence of the Gulf Stream on the sea around West Cork makes for ideal diving conditions – clear, unpolluted waters, colourful and abundant sea life, pleasant temperatures. From Baltimore you can explore reefs around the Fastnet and Stag rocks or the numerous wrecks, ranging from a man o' war to the spectacular 160,000 ton ore-carrier Kowloon Bridge and including the U-boat U260. The islands of Roaringwater Bay provide sheltered dive sites in any weather, while fans of drift diving will enjoy an opportunity to dive the Gascanane Sound between Cape Clear and Sherkin islands. Local dive centres provide a full range of services, including trips by hard boat or RIB, equipment sale and hire, training courses and technical support. From beginner to experienced diver, Baltimore has much to offer.

Non-divers, too, can experience the beauty of the underwater world through snorkelling, an activity that can be enjoyed by almost anyone from the age of six upwards. A guided snorkelling tour makes an ideal family outing.
