About this site
Alisa is a reef site off the Antrim coast of Northern Ireland, on the North Channel stretch of this coastline rather than the inland Lough Neagh shore. It reaches a maximum depth of around 55 metres and is rated a technical dive, placing it well beyond the shallower sites typical of this coast. The surrounding area mixes open sea diving along the North Channel with freshwater options further inland around Lough Neagh, but Alisa itself is a deep offshore reef dive.
