Do I get wet at Niagara Falls?
Yes, you will get wet at Niagara Falls, especially if you do the classic Maid of the Mist boat tour or Journey Behind the Falls. On the Maid of the Mist, you're basically on a boat that drives right into the base of the American Falls and Horseshoe Falls. You get absolutely soaked—think standing in a heavy rainstorm with wind. They give you a cheap blue poncho, but your shoes and pants will still get wet. The boat runs from around $25 per adult, and operates April to November. If you want to stay dry, skip the boat and just view from the observation decks on the U.S. or Canadian sides—you'll still feel mist but won't need a towel.
For a less intense soak, try the Cave of the Winds on the U.S. side (around $19 per adult). You walk on wooden decks right next to the Bridal Veil Falls, and they give you a sandal-like shoe cover and a poncho. You'll get wet, but it's more of a controlled spray than a full drenching. If you're visiting in winter, the mist can freeze on everything, so dress warm and expect icy paths. Bottom line: if you don't want to get wet, stay on the sidewalk near the falls, but that's like going to a water park and not getting in the pool.
