The hill settlement of Nainital, in the Kumaon region of Uttarakhand, was a popular summer retreat for the British during the time they ruled India. It features emerald colored Nainital (Naini) Lake and an action-filled strip called The Mall, lined with restaurants, shops, hotels, and markets. Enjoy one of the many forest walks, explore the surrounding area on horseback, or relax on a boat in the lake. This destination gets very crowded during summers, especially on weekends, due to its proximity to Delhi. Around Nainital, you'll find Jeolikote, Bhimtal, Ramgarh and Mukteshwar which are all less developed and quieter places to stay.
