Castlegregory, named after a castle built by Gregory Hoare in the 16th century, is located on the Northern side of the Dingle Peninsula dividing the bays of Tralee and Dingle. Located to the north of the village lies the Maharees Peninsula made famous for its sandy beaches and clean water. Off the Peninsula lies a group of seven Islands simply know as "The Maharee Islands". Although the castle from which Castlegregory derived its name is no longer there, there is plenty to see in the area. There are a large number of Early Christian remains such as the Kilshannig Cross out in the Maharees, however the area is probably best known for its beautiful walks and countless lakes. South of Castlegregory is one of the most beautiful places on the Peninsula – Glentassig.
