Spend a day exploring Lombok's northern part, visiting pristine natural landscapes and learning about the history and culture of the local. In the morning, first make your way out to Malimbu, a lookout point. From here you can see the nearby Gili Islands and Bali's Mount Agung. Continue to Sendang Gile Waterfall, on the foot and slope of Mount Rinjani. The cool, fresh air and calm hill will provide a comfortable resting point, and you may choose to "freeze" yourself in the inviting cold falling water. Then visit Senaru, a traditional village where mountain tribal life and the civilization of past centuries still exist. Finally, visit Bayan Old Mosque, one of the inestimable historical Islamic heritage sites in Lombok which is believed to have been built upon the Islamic people's arrival in the 16th century.
