Yes, in early days some lodges were built in the heart of the jungles of Chitwan National Park. But after last two decades, the government and forest department restricted lodge being located inside the park. Which can be disturbing to wild-life and to save the pristine environment. Where all lodges, hotels and resorts are all outside the Park areas near to its buffer zone. But visitors are allowed for jungle and elephant safari inside the park for certain duration of time as fixed by the Forest Department and Park official or authority.
