Niagara Adventure Pass

The Niagara Adventure Pass is a great way for tourists visiting Niagara Falls to save some money during their stay.  For C$44.95 (plus tax) you'll be able to get a combined admission pass to the Maid of the Mist, Journey Behind The Falls, White Water Walk and Niagara's Fury.  In addition, you'll get unlimited access to the Niagara People Mover bus to get you to and from every attraction.  If you're planning on hitting up these attractions anyway, getting this pass in a no-brainer.  It can be bought both online at the link above, or at any of the attractions or Visitor's Centers around Niagara Falls.

Journey Behind The Falls

Want to experience the true power of Niagara Falls?  Well, this is about as close as you can get.  The "Journey Behind The Falls" attraction allows you to enter into caves with exits that go right behind the falls.  The sheer power you'll feel is quite extraordinary.  However, the best views are had when you walk just to the side of the falls.  

From here, you'll get a great view, as shown below, of the Canadian Horseshoe falls.  From the second you exit the doorway, you'll feel the mist hitting you, and as you get closer to the falls, it'll feel more like you're in a storm than anything else.  

The free ponchos that are provided are a must-need (unless you want to get soaked).  You should also make sure you take either a water proof camera or secure it in a way so that it won't get wet if you want to continue taking photos on your trip.

If you're considering doing this attraction as well as the other popular ones in the area, I'd highly recommend getting the Niagara Falls Adventure Pass to save a few bucks.  It combines the price of this attraction, the Maid of the Mist, the White Water Walk and Niagara's Fury all into one.
