Santorini Kastelli SPA Resort 5*

Gracefully lying below the hill of Ancient Thera and a breath away from the famous Kamari beach, Santorini Kastelli Resort is a peaceful luxury retreat that combines an idyllic and convenient location, with upscale accommodation, state-of-the-art facilities, and impeccable services. Following a Cycladic village-like contour, this 5-star resort has it all: four swimming pools, a poolside restaurant and bar, spa facilities, a fitness center, a floodlit tennis court, a library, and a conference hall.

Designed to exude a sophisticated and laid back ambiance, lavishly appointed with high-end amenities, all the suites and rooms of Kastelli Resort open out to a balcony or veranda overlooking the glistening turquoise waters of the pools or the fragrant, lush gardens. Grab a refreshing drink from the pool bar and relax on a sun lounger, and later on, relish a delicious lunch or dinner at the poolside restaurant. Indulge in relaxing spa treatments, keep up with your fitness routine in the gym, enjoy an exhilarating tennis game with your friend at the tennis court, draw inspiration reading a book at the library corner, and plan your successful business or memorable social event at the conference center. At Kastelli Resort, you will have everything at your feet! Welcome, to your oasis of relaxation in Santorini!


Unwind and enjoy the delectable cuisine of “Lydia”, Kastelli Resort’s poolside restaurant. The open-air “Lydia” Restaurant is located at the main pool area, set in a relaxed atmosphere of casual sophistication. The restaurant offers a Greek Mediterranean cuisine, with divinely delicious dishes that are masterfully prepared with locally sourced ingredients of the highest quality. Starting early in the morning, the restaurant serves a delightful American buffet breakfast under the shade of the pergolas, offering later on scrumptious lunch options, and romantic candlelit dinners by the pool. Furthermore, at the Pool Bar on-site, you can cozy up  listening to relaxing music and enjoy a cup of coffee, fruit juices, beverages, and drinks, including delicious cocktails!


Offering the ultimate pool escape in Santorini, Kastelli Resort features four pools for you—a main outdoor large swimming pool along with three smaller ones, all of them equally indulging. Immerse yourself in the crystalline turquoise waters of the main swimming pool, and soak up the sun lying on a cozy sun-lounger, while enjoying a refreshing cocktail, a snack, or light meal from the Pool Bar.

The “Jacuzzi Pool” nearby, is set with a comfy lounge area, perfect for precious relaxation time among the trees. The “Pistachio Pool”, as its name denotes, is surrounded by pistachio trees, along with palm trees, and is the ideal venue for romantic wedding receptions or other social events. Last but not least, the “Infinity Pool” is a small pool next to our vineyard, featuring a lovely waterfall installation for offering zen moments, listening to the sound of the gurgling water. As if these upscale pool spots weren’t enough, Kastelli Resort also offers three additional semi-private pools, exclusively shared by the suites and rooms that compose the “Executive Neighborhood”.
