Coney Island can be reached at low tide.
There are 14 pillars which were erected in 1845 and act as markers to assist you getting safely to the island from Cummeen strand. The total distance is 2.4km.
The name means island of the rabbits, just because there is an abundant amount of rabbits on the island. The island is also called Inishmulclohy island, named after a family that lived there in ancient times.
The island has many associations with St Patrick. One of the relics on the island is St Patrick's chair, a wishing chair where you are allowed one wish per year.
At the back of the Island is a fantastic beach ( http://www.outdoorfitnesssligo.com/cartystown-beach.html ) which is worth a visit, especially on a nice day.
When you are travelling to Coney Island, always check the tides before you attempt the crossing.
