War of 1812 markers exist, but don't expect a tour.

Yes, there are some, but they’re scattered and often overshadowed by the islands’ later tourist-boom history. If you’re looking specifically for War of 1812 signage (say, around the Thousand Islands or Lake Ontario), you’ll find a handful — usually at fort sites, battlefields, or small wayside pull-offs. But the early tourism era (steamboats, grand hotels) gets way more attention because that’s what built the towns.

Your best bet is state or provincial parks (e.g., Sackets Harbor, Fort Ontario, or the St. Lawrence Islands National Park). But don’t count on a cohesive trail. You’ll have to do some digging ahead of time or you’ll drive right past them.

If you want the full story, grab a guidebook or a local history pamphlet. The markers tell you just enough to get you lost in Wikipedia later.
