Magheraroarty is located in a rural area on the North Coast of Donegal, approximately 9 km from the town of Falcarragh. Magheraroarty beach consists of a long sandy beach. It is on a spit of land with the Atlantic Ocean to the West and Ballyness Bay to the East, and the island of Inishbofin to the North. The beach is west facing into the Atlantic Ocean and gets a strong wash of water from the rough sea directly onto the beach. With shifting dunes along the coastline which are backed by vegetated dunes, these are vegetated by Marram Grass. Humid dune slacks occur on the fixed dunes on the Magheraroarty dune system.
