Lough Dan is a hidden gem nestled in Wicklow Mountains National Park, offering a serene escape from the hustle and bustle of city life. Access to the lake was temporarily closed due to irresponsible camper behavior, but it's now back open for visitors to enjoy. With picturesque walks and hikes leading to the lake, including options from the Old Military Road, Lough Dan House, and Ballinastoe Car Park, there are plenty of opportunities to explore this tranquil spot. Just remember to respect the area, leave no trace, and soak up the beauty of this secluded lake in the heart of nature.
