Lovely day on Mount Arroo with a visit to Lough Arroo and finally a swim in Keeloges lake more commonly known as Tin Whistle lake. Arroo is the outlier of the Dartry mountain range. It overlooks Lough Melvin and the Glenade valley. The terrain is generally boggy with long grass and heather which makes for slow progress and the fog which covered the summit on our ascent meant the views were hidden at that point. . We stopped at Lough Arroo for lunch and then finally made our way across the boggy ground to reach the lovely Tin whistle lake. Not a whistle in sight but the swim in the lake was unreal. It was the highlight of the day.
