Castle Rock is a village in the Uttara Kannada district of the Indian state of Karnataka. The village is located in the Western Ghats on the state’s border with Goa – at an elevation of 621 m (2,040 ft).
Located in a heavily forested area, Castle Rock’s vegetation is moist tropical deciduous. Manganese mines form the main economy of the region. The village lies within the Dandeli Tiger Reserve.
For many years, the village marked the frontier between Portuguese-held Goa and British-held India. A metre gauge railway line used to connect the Goan towns of Vasco and Margao with the rest of India and was the only rail link in the state till the Konkan Railway started services in the early 1990s. In the early 1990s, the Indian Railways converted the metre gauge line to broad gauge, thus connecting the old rail network with the rest of India. Metre gauge tracks can still be seen at the Castle Rock railway station.
