One of Ireland’s favourite locations for recreation, school tours, team building, personal development, survival training and much more. We specialise in combining the great outdoors with a real sense of fun. Derg Isle is nestled on the shores of Lough Derg and is a truly unique location. We are directly connected to the lake with direct access to the lake and our own island. The facilities at DergIsle have been developed with outcomes in mind. We specialise in tailoring each visit to produce positive and meaningful results.
