Natural Serenity

Millcroft Inn & Spa is a historic countryside retreat located at 55 John Street in Alton, in the Town of Caledon, Ontario. The property is built around a stone mill originally constructed in 1881 as the Alton Knitting Mill, which has been designated a heritage property by the Town of Caledon under the Ontario Heritage Act. Set on 100 acres of protected woodlands and meadows adjacent to Shaw’s Creek, the inn features three distinct accommodation buildings, a 9,000-square-foot full-service spa, outdoor hot spring pools, Headwaters Restaurant and 25 acres of sugar maple trees from which maple syrup is produced on-site each year. Millcroft Inn & Spa is part of the Vintage Hotels collection and is located less than one hour from Toronto.

Millcroft Inn & Spa is located approximately 80 kilometres northwest of downtown Toronto, in the village of Alton in the Town of Caledon. The drive from Toronto typically takes under one hour, depending on traffic. The property is accessible via Highway 410 North to Hurontario Street through Caledon. Pearson International Airport is approximately 58 minutes by car. Millcroft Inn & Spa is also within approximately 45 minutes of Kitchener-Waterloo and 15 minutes of Orangeville.

Millcroft Inn & Spa features two outdoor hot spring pools maintained at approximately 104°F (40°C), open year-round daily from 8:00 a.m. to 9:00 p.m. The hot spring pool experience includes a polar plunge pool—a cold-water contrast pool maintained at approximately 45°F (7°C)—designed for contrast hydrotherapy, a wellness practice that alternates between hot and cold immersion to increase circulation, reduce muscle tension and boost energy. Overnight hotel guests have complimentary access to the outdoor pools as part of their stay. Day passes for the hot spring pools and other spa facilities are also available to non-staying guests, subject to availability, with the day pass fee waived for guests who book a spa treatment.

Millcroft Inn & Spa is the only Vintage Hotels property located outside the Niagara region, set in the Caledon Hills approximately one hour northwest of Toronto. While Prince of Wales, Queen’s Landing, Pillar and Post, Inn On The Twenty and Moffat Inn are all situated in or near Niagara-on-the-Lake wine country, Millcroft offers a distinct countryside setting defined by protected forest, Shaw’s Creek Falls and Ontario’s Niagara Escarpment. It is also the only Vintage Hotels property with outdoor hot spring pools and contrast hydrotherapy, on-property maple syrup and honey production and accommodation in a converted 19th-century heritage mill building. Millcroft is the natural choice for Toronto-area guests seeking a countryside spa retreat rather than a wine country destination.

Millcroft Inn & Spa offers accommodations across three distinct buildings on the 100-acre property. The Main Mill rooms are located in the original 1881 heritage stone mill building, with views of the Mill Pond and Shaw’s Creek Falls, and include features such as king-sized beds and heated towel warmers. The Manor House features spacious rooms in the original country mansion, some with private verandas overlooking the grounds. The Crofts are self-contained chalet-style units with private patios or hot tubs, set among the wooded gardens. All rooms across all three buildings are decorated with European and Canadian antiques and include Nespresso machines, flat-screen TVs and evening turndown service.

Yes. Millcroft Inn & Spa is consistently rated among Ontario’s top romantic retreats, combining a heritage countryside setting, outdoor hot spring pools, couples’ spa treatments and fine dining at Headwaters Restaurant. The Crofts accommodation units are particularly popular for romantic stays. The Nordic Lagoon Bath Ritual and private hydrotherapy experiences at the Millcroft Spa are designed for two guests. The property’s 100-acre forested setting, walks along Shaw’s Creek and proximity to the Niagara Escarpment add a scenic dimension that distinguishes a Millcroft stay from an urban or wine country hotel experience.
