I am from Costa Rica and will travel to Niagara Falls in November... What do I need to pass to the Canadá side? Not sure if Skywheel is on the Usa side or Canadá side???

You will need your passport and the sky wheel is on the Canadian side.

Your Passport Canadian side

Canada side

Passports I would be overly prepared. It was intimidating crossing I had photo ID plus birth certificate. But soo worth it the Falls are breathtaking

If you are flying to Niagara falls in usa, the access to the Canadian side by walking or car you will need only your passport. Recommend to try the Canadian and the USA side of the falls.

That is what I am worry That I mamy need a Canadian Visa

Depending on which passport you have, I believe you might need a Canadian Visa to get to Canadian side but I would call an embassy to confirm.
