Portland is one of the most popular south coast diving destinations in the UK. The 18 mile Chesil Beach can offer excellent shore diving with scenic dives and shallow wrecks all within swimming distance.  

There are a number of dive boats operating out of Castletown, providing shuttles, day charters, harbour and offshore wrecks, drift and night dive sites, all at varying depths.  Air and Nitrox fills are available at Portland Oceaneering.

Protected by the harbour walls against even the strongest winds, Portland Harbour, with its sheltered wreck sites, can still be dived when gales prevent offshore diving.

The essential guide for anybody wishing to dive the wrecks around South Dorset.
