Discover the scenic St. Lawrence River with this 2-hour islands, lighthouse, and castle cruise from Clayton. Enjoy views of Boldt Castle and Millionaires Row.
If you’re looking for a scenic escape on the water that combines natural beauty with a touch of history and luxury, the Islands, Lighthouses, and Castle Tour on the St. Lawrence River might just be the perfect fit. This approximately two-hour boat ride offers a relaxed way to explore the famed Thousand Islands region, renowned for its stunning landscapes, historic lighthouses, and opulent summer homes.
What we especially like about this tour is its accessible price point of just $27 per person, making it a great value for a memorable experience. Plus, the fact that it’s booked about 196 days in advance shows it’s a popular choice, and for good reason. On the downside, the tour’s duration means it’s more of a quick overview rather than an in-depth exploration, which might leave some wanting more if they’re looking for detailed history. Still, it’s perfect for visitors with limited time or those who want a relaxed introduction to the region.
This cruise is ideal for travelers who enjoy beautiful scenery with a mix of nature, history, and a touch of luxury.

Starting at Clayton Waterfront, the cruise begins with a gentle sail down the St. Lawrence River, offering panoramic views of the surrounding islands and the chance to spot the region’s famous opulent summer homes on Millionaires Row. This stretch alone is worth the price, as you’ll see the homes that have been vacation spots for wealthy families for generations, with some dating back over a century.
Next, the vessel passes Wellesley Island and Thousand Islands Park, giving you a sense of the area’s natural charm. These points are perfect for photography, especially as the boat glides past lush greenery and rocky shores.
Rock Island Lighthouse and Keeper’s Cottage provide a real highlight. Sitting along the shipping channel, this lighthouse has a storied past, and the nearby keeper’s cottage adds a touch of history. The lighthouse itself is a classic symbol of the region’s maritime heritage and a favorite subject for photographers.
The tour then makes a full circle around Boldt Castle on Heart Island, passing the famous yacht house designed in a Rhineland style. While the castle itself is not included in this trip, the boat’s vantage point offers incredible views of this opulent, fairy-tale-like mansion that draws millions of visitors each year. Passengers often comment that seeing Boldt from the water gives a different perspective—less crowded, more majestic.
Finally, the cruise stops near Bush Island to see Sunken Rock Lighthouse, adding to the maritime mosaic. The final leg takes you past Fisher’s Landing on Rock Island, giving a well-rounded view of the region’s maritime history.
One of the best aspects is the uninterrupted views of the islands and landmarks. Unlike visiting Boldt Castle in person, which involves ferry rides and long lines, this cruise provides a relaxed, moving panorama—a perfect way to get a sense of the area’s geography and grandeur without the crowds.
The narration, though not detailed in the provided info, likely enhances the experience by offering background on each landmark, making the scenery more meaningful. The group size, capped at 65, helps maintain a friendly, intimate atmosphere, avoiding the overwhelming feeling of large tour buses or packed boats.
