Alexandria Bay, New York sits in the middle of the Thousand Islands region along the St. Lawrence River. On paper, it sounds like a perfect destination. Islands, castles, water activities, small-town charm. The kind of place that gets hyped up fast.
The reality is a little more balanced.
There’s a lot here, but not all of it hits the same. Some stops are worth your time. Others feel more like tourist fillers.
What Alexandria Bay, New York Actually Is
Alexandria Bay is a small waterfront town built around tourism.
During peak season, it gets busy. Shops, restaurants, boat tours, and people moving in every direction. Off-season, it slows way down.
Most of what you’ll do here revolves around:
- the river
- the islands
- a handful of major attractions
This isn’t a deep city. It’s a destination you explore in pieces.
Alexandria Bay, New York: Unveiling the Wonders of Boldt Castle

Boldt Castle is the reason most people come here.
And honestly, it delivers.
The castle sits on Heart Island and looks exactly how you’d expect. Large, detailed, and completely out of place in the middle of the river.
You’ll take a boat to get there, walk the grounds, and explore the interior. It’s well maintained and easy to navigate, which makes the visit smooth.
The backstory adds to it too. Built as a symbol of love, then left unfinished. It gives the place a different feel compared to just another historic building.
If you only do one thing in Alexandria Bay, this should be it.
Alexandria Bay, New York: Visit the magnificent Singer Castle

Singer Castle is the quieter alternative.
Smaller crowds, more hidden details, and a slightly different vibe. It feels more like a private estate than a major attraction.
You’ll still need a boat to get there, and the experience is more guided compared to Boldt.
If you have time for both, do it.
If not, Boldt is the better first pick.
Alexandria Bay, New York: The Thousand Islands Experience
The real draw here isn’t just the castles. It’s the water.
The Thousand Islands region is exactly what it sounds like. Small islands scattered across the St. Lawrence River, some with houses, some untouched.
From land, you only get part of it.
Out on the water, everything makes sense. You see how the islands are laid out, how close they are to each other, and how much of this place you’d completely miss otherwise.
Kayaking is an option if you want to go slower and stay close. But for most people, there’s a simpler way to experience it.
Boat Tours (This Is How You Actually Experience It)
This is where it comes together.
You can walk the town all you want, but Alexandria Bay doesn’t fully hit until you’re on a boat moving through the islands.
We booked a tour that took us across the river, around multiple islands, into Canadian waters, and included access to Boldt Castle. It turned what would have been a basic stop into something much more complete.
One solid option:
Gananoque: 1000 Islands Cruise & Optional Boldt Castle Entry
- 4.5 stars (4,000+ reviews)
- 1, 3, or 5-hour options
- 5-hour includes Boldt Castle admission
- Onboard audio commentary (English & French)
- Food and drinks available
This is the kind of tour that handles everything in one shot. No figuring out routes, no piecing together stops.

If you’re deciding between options:
- 1 hour – quick overview
- 3 hour – balanced option
- 5 hour – full experience (best pick)
Trying to do this solo without knowing the area is a headache. Between navigation, island access, and crossing into Canada waters, it’s just easier to let the tour handle it.
Alexandria Bay, New York: The Town Itself
Back in town, Alexandria Bay is exactly what you’d expect from a tourist-heavy waterfront area.
You’ve got:
- souvenir shops
- restaurants
- ice cream spots
- marinas
It’s not bad. It just is what it is.
You’re not coming here for deep culture or hidden gems. You’re here to support the main attractions and fill in the gaps between them.
A walk along the waterfront is worth doing once.
After that, you’re moving on.
Thrilling Water Activities and Island Hopping:

Water Activities (Optional, Not Required)
If you want more than sightseeing, there are options.
Jet skis, paddleboarding, boat rentals, and general water activities are all available.
They’re fun if that’s your thing. But they’re not what defines this place. You can skip them and still get the full experience.
Alexandria Bay, New York: Festivals and Events
Alexandria Bay leans hard into themed events and festivals, especially in the summer.
Pirate-themed weekends, live music, and general waterfront events bring in crowds.
If you happen to be there during one, it adds energy. If not, you’re not missing anything essential.
Alexandria Bay, New York: Getting There
This isn’t a quick hop for most people.
Driving is the most common way to get here.
From my trip, it was about a 6 to 7 hour drive, which makes it more of a commitment. You’re not casually dropping in for the day unless you’re already nearby.
Flying is an option through smaller regional airports, but most people will drive. These air gateways include the Ogdensburg International Airport and the Watertown International Airport.

- 1 full day (rushed but doable)
- 2 days (ideal)
Day 1:

Anything beyond that, and you’re stretching it.
