Situated on the east side of Ramore Head and close to Lower Landsdowne Crescent is the Coastal Zone. Originally the building was used for seaweed and salt baths for guests staying at the Northern Counties Hotel but nowadays it houses an interesting display of natural attractions including seashore exhibits, touch tanks and live sea creatures. It is a great experience for young children introducing them to the wonders of the sea life around are local shoreline. There are also opportunities for rockpool rambles, fossil hunts and bird watching, there is always something different going on each year for the visitor. You can sit back and watch a film or video in the audio-visual theatre, where in summer, talks are often held on various subjects relating to the ocean.

Sighting of Seals, dolphins and porpoises are often reported from here. A great location for a family picnic. Close by you'll find the Portrush Sill, a protected outcrop of metamorphosed Jurassic clay full of ammonite fossils, during the 18th century it became the centre for debate between the Neptunists and the Plutonists. The Neptunists believed that  basalt crystalised from seawater  while the Plutonists believed it to be volcanic activity. The argument was settled here by the evidence of ammonite fossils in mudstone which had been baked by the overlying sill. You can walk over the rock and still see the fabulous patterns of ammonites in the mudstone and the layer of  magma which covered and intruded into it. This was formed at the same time as the Giant’s Causeway some 60 million years ago.
