The Hilt-on Shillim Estate Retreat and Spa is a massive property spread over 321 acres, nestled in the serene hills of Lonavala. The forest villas offer unparalleled views of the ghats, and the infinity pool is a must-visit for a surreal sunset experience. The staff is courteous and helpful, and the wellness facilities are top-notch. However, the food quality and taste are average, and the service can be slow at times. The property lacks signages, and the approach road is off-road in between. Overall, it's a peaceful and calm experience, perfect for a 1-2 night getaway.
