I visited in Yercaud in June 2023 and stayed in Sterling resort for 2 nights and 3 days. I booked classic room for both nights. Resort was very good. Rooms were little small but it was manageable. Restaurant food was very good and we got excellent service by Mr Kuldip and Mr Satyajit. I would definitely recommend to visit Yercaud and stay at Sterling.
