Castle Grove is a family-run Georgian house, built in 1695 and set is its own 250-acre estate with gardens designed by “Capability” Brown. Situated at the end of a mile-long avenue on the shores of Lough Swilly, it’s the perfect base from which to explore beautiful Donegal and Wild Atlantic Way.

Two drawing rooms with open fireplaces, a library, a cosy bar and bedrooms are furnished with antiques and luxury fabrics. The award-winning fine-dining restaurant serves excellent cuisine prepared by master chefs, who combine locally-sourced produce with organically grown fruit and vegetables from the four-acre walled garden.

Castle Grove Country House is one of the few remaining private estates in the northwest of Ireland. Pass through the gates and you are in a different world, an oasis of privacy and tranquillity rarely found today. This Georgian house overlooking Lough Swilly is ideally placed between Letterkenny and Rathmullan and within driving distance of 20 golf courses. Come and dine, stay and relax at Castle Grove in an atmosphere of comfort and hospitality.

Ideal for weddings and special occasions, Castle Grove is described as a "hidden gem in Donegal".
