Nagarhole National Park is spread over 247 square mile in Karnataka. The landscape is one of gentle slopes and shallow valleys. Dry deciduous forest trees are leafless in the summer rather than in the winter. There are grassy swamps where the soil is clayey, perennially moist, and which support a luxuriant growth of green grass all year. The change in terrain throughout the park is refreshing and the river system provides a unique wildlife viewing experience.
