Last year I took a visit at Niagara falls, which is collective name for three waterfalls(two american and one canadian) that straddle between borders of Canada and United States. I had an opportunity to take a ride on a ferry,called "The Maid Of The Mist", and feel the joy of being so close to the majestic falls!
By the way, the ride costed only 15$,that's affordable for everyone!
This picture is of a canadian ferry ...
Besides the falls,there are more places to see in that area.
You can also purchase some souvenirs for you and your friends at the local store.
and enjoy appetizing ice-cream _
I've had unforgettable experiences while being at niagara falls. I can totally recommend you to go there. There are bunch of hotels in that area that are not too expensive , so money should not really be the big problem.
