Located in nearby Subathu (around 20 km from Kasauli), the Gurkha Fort dates back to the early 19th century. It was built by Gurkha warriors and later used by the British. The fort, surrounded by dense forest and scenic hills, offers a mix of history, nature, and solitude. Though not heavily restored, the ruins and view make it worth a visit. Ideal for history buffs, trekkers, and offbeat explorers looking for a quiet day trip.
