After living nearby for years, I finally checked out the Fort. It's very interesting, but also sad,…read moreas the death toll was a lot higher than I had heard. (And so POINTLESS!)
The Americans blew up the fort when they withdrew in 1814, and it lay in ruins for over a hundred years, but during the Great Depression it was rebuilt as a tourist attraction in a government make-work project. The displays are interesting, and the tours are very well done.
For about twice the price of a single admission, you can get a season's pass, which lets you go back as many times as you want. (Which is good if you want to see both the 2-pounder and the 10" mortar in action, since you'd need to go in both on a Saturday and on a Sunday.) A season's pass is a good thing for locals to get, so you can take visitors to the Fort and won't need to pay for yourself each trip.
The best time to visit is on the weekend, since the 2-pounder cannon is fired at 12:30 on Saturdays and the 10" mortar is fired at 2:30 on Sundays. (Mondays to Saturdays, it's the 3 1/2" mortar at 2:30.) There are musketry demonstrations during every tour (hourly most days), and you get a cookie and a glass of lemonade at the end of the tour. Warning: the fort was built long before anybody thought of wheelchairs, so there are stairs and other access barriers. Niagara Parks has done what they could to improve access, but if you can't climb stairs, there are some parts of the fort that you just won't be able to see. I'm a "read every single placard" kind of guy, so it takes me about two and a half hours to see the whole thing. (The tour doesn't take anywhere near that long, but you can wander around on your own after the tour, and I always do.)
The stuff in the gift shop is pretty overpriced, which is a shame because some of it's nice. (And, to be honest, there aren't very many places that sell souvenirs of Fort Erie. Canada, yes. Ontario, sure. Niagara Falls, definitely. Fort Erie, not so much.)
The food in the snack shop is good enough that some of the locals pop in just to eat there. My sweetie and I have frequently strolled in just for lunch.
If you're driving, the easiest way to find it is to head down the Niagara Parkway from Niagara Falls. Drive under the Peace Bridge, and follow the road around to the right. If you're coming down the QEW or across the Peace Bridge from Buffalo, take the exit for Central Avenue (the last exit before the bridge, or the first exit after the toll booths, depending on your direction of travel), turn right on Central, then go to the bottom of the hill and turn right onto Lakeshore. In either case, the visitor's centre will be the first building on your left once you have passed under the bridge or turned onto Lakeshore.
If you're taking Niagara Transit route 751 (Fort Erie) get off at the stop at Albany and Ferguson, walk two blocks down Ferguson, and the fort will be to your left and across the street.
If you have a battery electric vehicle or a plug-in hybrid, there are two free charging stations in the parking lot close to the front door of the visitor's centre. The charger on the post with the sign saying that parking is for "electric vehicles only" has a J1772 plug. Around the back of the same post, there's another charger with an NACS (Tesla) plug. So, ideally, two people should be able to charge their vehicles at the same time, and you should be able to get a decent charge in the time it takes to do the tour, wander around on your own, have a meal, and browse the gift shop. Unfortunately, there's only one sign, even though there are two chargers, and while the cables are long enough to reach cars parked in the spot beside the charger, they aren't long enough to reach the spot on the other side of that one. Some drivers of vehicles burning dead dinosaurs who don't know the situation (and, sadly, some who should) tend to park in the spot beside the charger, so being able to charge in that spot is hit or miss. Then again, on busy days, it's common for both chargers to be in use. I've noticed that attendance tends to be lower on days that are overcast or rainy, so if the fort is close to the range limit of your vehicle, you might want to visit on a day like that and bring a raincoat, so you can be more likely to be able to get a charge. If all else fails, there are other chargers not too far away, but all the chargers within Fort Erie that I know about have J1772 plugs, so if your car needs an NACS or ChaDeMo plug, bring an adaptor. (And if you go to the chargers at Canadian Tire or A&W, you will need to be in the Flo network.)
