Thousand Islands Cruises: How to Choose the Best Boat Tour

A castle tour, an evening river excursion, or a brief boat tour past island homes: what's your fancy?

Thousand Island Cruises feature a variety of excursions on the St. Lawrence River from Clayton and Alexandria Bay, New York. Scenic tours and historically focused cruises are available, as well as opportunities to tour a castle or lighthouse.

The best way to narrow down the variety of boat tours is to first decide on your point of departure, what you'd like to see, and how much time you have available. Use this guide to compare and contrast your options and plan your adventure!

Which Thousand Islands Cruise Is Best for You?

For a first-visit experience, a narrated sightseeing cruise is a good introduction. Choose a castle tour if you want to see a historic building, a lighthouse tour if you'd prefer to cut loose ashore, or a sunset cruise for an evening on the water. It all depends on your schedule and where you're coming from. 

Durations are approximate and additional time should be allowed for check-in and any optional stop you wish to make. Please check the selected sailing for current availability and inclusions. 

Start with Your Departure Point

Thousand Islands Cruises from Clayton

Clayton is a departure point for lighthouse excursions, overnight trips with island visits, and two-hour cruises. Listed departures also include the Boldt Castle & 2 Nation Tour and a sunset cruise.

If you're staying in or near Clayton, start exploring from here, and you'll have time for a late breakfast, a waterfront stroll, or getting your family together before departing.

Thousand Islands Cruises from Alexandria Bay

Alexandria Bay departures include the Millionaires Row Tour, the 2 Nation Tour, the Singer Castle Tour, and the Twilight Cruise.

Choose your route before arranging the rest of the day. A one-hour outing can fit into a short visit, while a castle tour needs a larger space in your schedule.

Use the exact meeting point on your confirmation when planning parking and arrival.

Choose the Experience You Want

A Short Sightseeing Cruise

If you are short on time, consider the Millionaires Row tour, which is a one-hour boat tour that begins in Alexandria Bay. This tour gives you great views of the river and also describes the history of the millionaires' mansions on the islands along the river. If you want a more extensive tour that tells you about the islands, lighthouses, and Boldt Castle, then you should take the two-hour Islands, Lighthouses, and Castle tour, which departs from Clayton. This is a good tour if you want to see sights while on the boat.

A Visit to Boldt Castle

If you want to see the castle, check out a tour that includes a stop on Heart Island, considering the time you'll have ashore and any separate admission fees.

The Boldt Castle & 2 Nation Tour from Clayton designates roughly 75 minutes for exploring the castle in its three-and-a-half-hour cruise.

 Note that the fees for both the island and the castle are separate from the price of the cruise ticket.

A Guided Singer Castle Tour

For a guided castle tour, check out the Singer Castle Tour  from Alexandria Bay. The tour includes admission to Singer Castle and a one-hour guided walk around Dark Island.

If you're looking for places to go that involve some history, this castle tour might be right for you. There's a lot of walking on this tour, so make sure to ask about accessibility options if you're bringing a group with special needs.

A Glass-Bottom Boat and Lighthouse Visit

The Glass Bottom Boat +  Rock Island Lighthouse tour option provides an additional choice for those looking for a more diverse experience on the river. 

This option includes viewing from both the glass bottom boat and a visit to Rock Island Lighthouse.

The duration of the tour is approximately two and three fourths hours long and includes an hour or so on the island. Admission to the lighthouse is included. 

The underwater visibility is dependent on the conditions of the day and should be inquired about separately from the accessibility of the walking path and lighthouse.

A Sunset or Twilight Cruise

An evening cruise ties perfectly into a day's tour of the area, allowing you to gaze across the river at the changing light on the islands.

Compare the two hour, Sunset Cruise from Clayton with the one and half hour, Twilight Cruise from Alexandria Bay. 

Choose your embankment point according to convenience and then check sailing times for your particular date. Sunset colors and visibility change with the weather.

A Longer Trip with Island Stops

If your goal is to make the cruise the centerpiece of your day's activities, the Ultimate Heart of Thousand Islands Sightseeing Tour makes that easy. 

Along with a five-hour cruise that includes two island visits, the tour also features an inside tour of Boldt Castle and the Rock Island Lighthouse plus a picnic lunch. 

This is worth thinking about considering the time and cost involved if you were to visit the sights on your own. 

Compare What Your Ticket Includes

Before going on a Thousand Islands boat tour, read the details of what is included in the tour and what isn't. Check: 

• Attraction admission: Whether castle or lighthouse entry is included.

• Time ashore: How long you can spend at each stop.

• Food and drinks: Whether a meal is provided or refreshments cost extra.

• Return arrangements: How you get back after any optional stop.

• Cancellation terms: Whether the ticket allows a refund, rescheduling, or both.

Use the terms attached to your selected tour and ticket. Some of them allow canceling the order under specific conditions, and some suggest that tickets are non-refundable but can be rescheduled. 

How Much Time Should You Allow?

Consider the whole outing, including travel to the dock, check-in, the cruise, and any necessary extra time ashore.

If you have only a part of a morning free, consider a shorter sightseeing tour, but leave a bigger gap in your schedule if you're considering a castle or lighthouse tour. Your day is more likely to flow smoothly if you keep most of the day open for a five-hour tour.

Consider family members' needs, including eating and napping, and how well they'll tolerate being on a boat.

When Should You Take a Thousand Islands Cruise?

The listed cruises run seasonally, so be sure to refer to the calendar for your travel dates prior to making any other arrangements.

A daytime departure allows for sightseeing along the waterfront and at islands of interest. An evening departure is perfect for leisurely explorations along the water's edge. 

Choose the departure that best suits your sightseeing interests and then check the forecast and available departures.

What to Bring on Your Boat Tour

A few useful items can make the trip more comfortable:

• A light jacket or extra layer.

• Comfortable shoes, especially for island stops.

• Sunglasses and sunscreen for time outside.

• A charged phone or camera.

• Your booking confirmation and any required identification.

Review tour restrictions on food and drinks, large bags, and accessibility. If you require or plan to use mobility devices or have children with strollers, please advise the tour company what accommodations they might need to make for you or your family including on the boat and during shore excursions.
