Spa Hotel for Sale near Alicante – Balneario de Aigües de Busot

Project Fact Sheet

What Exactly Is for Sale?

This spa hotel for sale in Alicante province is a rare opportunity to acquire one of the most recognisable historic buildings of the Alicante hinterland: the thermal spa complex of Aigües de Busot. The sale combines two elements. The first is the historic hotel and spa building itself, a large, landmark structure that dominates the hillside and is sold as a renovation project. The second is the surrounding estate land, which the seller presents as suitable for approximately 100 new homes.

Where Is This Spa Hotel for Sale in Alicante?

Aigües is a small hillside village in the Alacantí district, set on the southern flank of the Cabeçó d’Or, a limestone massif that rises behind the coast of El Campello and Busot. The spa sits roughly one kilometre from the village, next to the thermal aquifer that gave the area its name — Aigües simply means “waters” in Valencian. From the estate the land drops towards the sea, giving long views over the Mediterranean, while the mountain rises directly behind. The well-known Cuevas del Canelobre show caves are in the same mountain, and the terraced landscape of olive and almond groves, stone walls and old irrigation channels surrounds the site.

Despite its peaceful setting, the location is well connected. Alicante city centre is around 20 minutes by car, the beaches of El Campello and San Juan are close by, and Alicante-Elche airport is about 40 km by road, with direct flights to most European capitals.

A Spa with More Than 200 Years of History

The healing properties of the Busot waters were described for centuries, and in 1816 the springs passed from the city of Alicante into private hands, beginning the history of the spa. From 1865 the Count of Casa Rojas developed the ambitious Hotel Miramar “winter station” around the springs: a grand hotel with a casino, ballroom, chapel, gardens, a navigable pool and sports facilities, whose golden age lasted until around 1930 and which even received a visit from the Spanish royal family. In 1936 the building passed to the State and was converted into a children’s sanatorium, and by the mid-twentieth century it had fallen out of use. Its monumental façade remains one of the most photographed landmarks of the province, and it carries a heritage story that very few new-build projects on the Costa Blanca can match.

The Architect’s Vision: Between the Water and the Mountain

A concept study dated September 2026 shows how the estate could be brought back to life. Its central idea is that the historic building must remain the protagonist. Rather than a second large block, the new homes step down the hillside in terraces, following the old stone walls and the traces of vanished buildings, with green roofs that extend the mountain and gardens, pools and water channels between them. Key principles of the study include:

• 99 homes in two independent phases — 63 units in Phase 1 and 36 in Phase 2, separated by the existing track, so investment and sales can be staged.
• A spa-focused ground level with shared services, patios, ponds, pools and a central water plaza inspired by the Alhambra.
• Homes of about 100 m² built, each paired with an open 5.5 m bay used as a private garden or terrace, giving roughly 11 m of frontage to the landscape.
• Dual-aspect layouts: every home looks to the sea on one side and to the mountain on the other, with natural cross-ventilation.
• Mediterranean passive design: thick stone walls for thermal mass, deep window reveals, protection from the western sun and planted roofs.

The study is an early design exploration, not an approved project. It illustrates one way the site could be developed and is provided to serious buyers as a starting point for their own feasibility work.

Why Is This an Interesting Investment?

Few assets combine genuine thermal springs, a historic landmark and sea views, and a spa hotel for sale in Alicante with this story is extremely scarce on the Costa Blanca. The estate offers several possible strategies: a boutique spa hotel with residences, a wellness resort, a residential community built around a restored heritage landmark, or a combination of these. The Alicante area benefits from year-round demand, over 300 days of sunshine a year and a major international airport close by.

Due Diligence and Buying Process

For an asset of this type, the planning position is as important as the price. The number of homes that can be built, the heritage protection of the historic building and the use of the thermal water should all be confirmed with the Aigües town hall and the relevant regional authorities, and reviewed by an independent Spanish lawyer and architect before any binding commitment. Full documentation will be shared with qualified buyers under a confidentiality agreement. The tax treatment of the purchase (transfer tax, or VAT plus stamp duty) depends on the seller and the structure of the deal; see our Spanish property taxes guide and our explanation of reservation and arras contracts.
