Carrick-a-Rede is a rope bridge in Northern Ireland located near Ballintoy city that links to Crrickarede island. The bridge was originally built by fishermen to get to the island to fish salmon. Today, it is no longer used for that purpose as there are barely any salmon left, and now acts as a tourist attraction and you may cross it for a fee of 5.90 pounds. For those on a budget, this may seem like a lot. I personally did not cross it, but the hike to it and the views are still quite a sight and you do not need to spend a pence to do that.
