Dal Lake is the most beautiful and second largest lake in J&K. It is nicknamed the "Jewel in the crown of Kashmir" or "Srinagar's Jewel". The shore line of the lake, about 15.5 kilometres (9.6 mi), is encompassed by a boulevard lined with Mughal era gardens, parks, houseboats and hotels. Scenic views of the lake can be witnessed from the shore line Mughal gardens, such as Shalimar Bagh and Nishat Bagh built during the reign of Mughal Emperor Jahangir), Zabarwan park and from houseboats cruising along the lake in the colourful shikaras. During the winter season, the temperature sometimes reaches -11 °C (12 °F), freezing the lake. The floating gardens, known as "Rad" in Kashmiri, blossom with lotus flowers during July and August. The wetland is divided by causeways into four basins; Gagribal, Lokut Dal, Bod Dal and Nagin (although Nagin is also considered as an independent lake). Lokut-dal and Bod-dal each have an island in the centre, known as Rup Lank (or Char Chinari) and Sona Lank respectively. Tourists reside in splendid houseboats to enjoy the peaceful and serene atmosphere of the lake.
