The Stone Mill Inn - St. Catharines, ON

Stay with $50 Dining Credit at Stone Mill Inn in St. Catharines, ON, with Dates Through July

Historic Boutique Inn Near Niagara Falls

The Stone Mill Inn itself is only a year old, but the building that houses it is much older. It was originally built in 1860 as a cotton mill—the structure was one of the first of its kind in Canada. Today, the architectural beauty of the historic structure has been restored—as you stroll through the halls of the Stone Mill Inn, you’ll notice wrought-iron gates, original stonework, and a grand staircase modeled after those on the Titanic. The inn is also just 15 miles west of Niagara Falls, so it’s a comfortable jumping-off point for exploring the peninsula.

You can put your $50 dining credit to use at the on-site Johnny Rocco’s Italian Grill. It serves tapas, gooey paninis, handcrafted pizza, hearty pastas, or sizzling entrees fresh from the grill including cedar salmon, chicken, veal, and New York steak. Alternatively, there’s Keg Steakhouse Bar & Grill across the street, which has prime rib, seafood, and sirloin.

Each of the inn’s 34 suites is unique and contemporary; some feature exposed brick walls and dark leather furniture. King and Jacuzzi suites are each decked out with a flat-screen TV, iPod clock radio, mini-fridge, microwave, and Keurig coffeemaker. You can even get a snip, style, or hair coloring at the Salon at Stone Mill. Meanwhile, the New Stone Mill Spa is the place to go for massages, facials, body wraps, and mani-pedis.

St. Catharines, Ontario: Historic Port City on Lake Ontario near Niagara Falls

The city of St. Catharines is right on a harborfront, situated between Lake Ontario and Niagara Falls in Ontario. There are galleries, restaurants, and boutiques along the pier, which is bookended by two lighthouses that date back to the late 1800s. At Lakeside Park, you can ride the famous antique Lakeside Park Carousel, which has offered five-cent rides for more than a century. Less than four miles (6 km) north is the terminus for three of the Welland Canals, a system of locks that extends all the way to Port Colborne on Lake Erie.

The area around St. Catharines is a globally recognized cool-climate region for winemaking. Nutrient-rich sediment from the surrounding Great Lakes helps winemakers produce top-notch rieslings, chardonnays, and pinot noirs. There are several nearby wineries that host wine-tastings and tours.

Located about 15 miles east of St. Catharines, Niagara Falls straddles the border between Canada and the United States. There are segments of the falls located in both New York and Ontario, but the Canadian side of the Niagara River is universally hailed as the finest vantage point to take in all three of Niagara Falls' photogenic brinks: American, Bridal Veil, and Horseshoe Falls. The iconic Maid of the Mist has ferried raincoat-clad passengers around the base of the falls since 1846. The tours run from April through October, depending on the river's ice conditions.

This is a beautiful hotel. The king suite was the ideal room for our stay. Big and well equipped. Highly recommend Johnny Rocco’s Italian Grill downstairs as well.

I can’t pick just one thing. The room was stunning. The vouchers are great and are good for a year. So you can take your time. Fantastic. I have three still to go back and use at my leisure. The ones we did use were great, and an approx. $15 per person value. Johnny Rocco’s was delicious. Can’t wait to go back
