Ranthambore National Park
Sitting on a rocky hill right inside the national park, the ancient Ranthambore Fort is a UNESCO World Heritage Site with a history stretching back over a thousand years. Driving up to the fort through the jungle — with monkeys on the walls and peacocks in the courtyards — feels entirely surreal. The fort itself has atmospheric ruined temples, medieval stepwells, and sweeping views over the forested valleys below.
The fort is accessible only through the park gates, so you need a valid safari ticket to enter. Combine it with a safari for maximum efficiency.
