Lough Tay, also known as Guinness Lake, offers stunning views of its inky black water nestled between Djouce Mountain and Luggala. Visitors can enjoy the picturesque scenery from various viewing points along the Sally Gap Drive, although access to the lake itself is restricted due to private ownership. The area is popular for hikes like the Lough Tay to Lough Dan walk and the challenging Luggala hike, providing opportunities to soak in the beauty of this iconic spot in Wicklow.
