Magilligan Point is the tip of one of the largest sand dune systems in the British Isles. The way the coastline constantly changes here is of particular interest and is one of the main reasons the site has been declared a nature reserve. In summer, many different wild flowers add a splash of colour to the dunes. Harebells and Bird's-foot Trefoil are followed later by Thyme and Pyramidal Orchids. On warm days, butterflies such as the common blue or meadow brown are plentiful. Also look out for the six-spot Burnet moth. For birdwatchers, Magilligan Point offers good views of seabirds using the narrows and in winter, migrating waders and wildfowl.
The Martello Tower was built in the early 1800s, as much for defence against American privateers as against the threat from France. It was equipped with a 24 pounder cannon and a garrison of 13. Over 200 similar towers exist worldwide.
