Château des Tertres is a four-star château-hotel set on the Route de Monteaux in Onzain, a village in the Loir-et-Cher department of Centre-Val de Loire, France, on the north bank of the Loire midway between Blois and Amboise. The 19th-century turreted manor sits within a private park of mature trees and formal gardens overlooking the Loire Valley vineyards. The 24 rooms and suites occupy the main château and a converted outbuilding, combining classic château décor — canopied beds, decorative plasterwork, period furnishings — with comfortable modern bathrooms. Superior rooms and Suites command the most expansive park and garden views and offer the largest floor plans. The hotel restaurant serves refined French cooking that celebrates the abundant produce of the Loir-et-Cher: Loire Valley river fish, locally reared poultry, seasonal vegetables from the kitchen garden, and farmhouse cheeses, accompanied by wines from the Touraine and Cheverny appellations stored in the estate's own vaulted cellar. An outdoor pool set within the formal grounds provides a quiet summer retreat. The property's position on the Loire's north bank makes it an ideal cycling base: the Loire à Vélo trail passes within close range, and Château de Chaumont-sur-Loire — a spectacular Renaissance and Gothic château on the riverbank hosting a celebrated annual international garden festival from April to November — lies 12 kilometres to the east. The medieval city of Blois with its architecturally complex royal château is 18 kilometres away, and Amboise, with the Château Royal and Clos Lucé (Leonardo da Vinci's residence), is 20 kilometres to the west. Château des Tertres organises periodic wine-tasting evenings and seasonal regional produce dinners that explore the breadth of Centre-Val de Loire's food and wine culture. The property's tranquil park and unhurried atmosphere distinguish it from busier riverside alternatives and appeal to travellers who prefer to combine Loire château visits with peaceful evenings in historic grounds away from the main tourist circuits.
