Witness one of the world's greatest natural wonders on a Niagara Falls day tour from Toronto. Composed of the American Falls, Bridal Veil Falls, and Horseshoe Falls, the Niagara Falls has the highest flow rate of any waterfall in the world — it is like more than a million bathtubs of water plummeting over the edge every second. So, don't miss your chance to soak up the stunning views and get soaked while at it.

A 20-minute boat ride from Cancún lies the small island of Isla Mujeres with its laid-back Caribbean ambiance, tiny streets lined with stalls, and street cafés in pastel-colored houses. Golf carts and mopeds dominate the streets, and although the island is only 5 miles long and half a mile wide, it still offers plenty of things to do and see. Everything from a beautiful palm-fringed white beach on the north coast to a dramatic rocky shoreline on the eastern side to a sea turtle sanctuary and the remains of a Mayan temple at the southern tip. If you're into adventure, then you should visit the Garrafon Reef Park & Beach Club, where you can go zip-lining, snorkeling, and kayaking. Lastly, a must-visit for nature and wildlife lovers is a tour to Isla Contoy, a nature reserve only inhabited by a few biologists and restricted to 200 visitors per day.

Perth’s main attraction is located where Perth meets the Swan River. The 82.5-metre-high Clock Tower, made of copper and glass, contains eighteen bells and is surrounded by a laid trail of ceramic tiles. Enjoy the view, learn about Perth's history and geography and perhaps leave a "love lock" on one of the railings.

Unlike most aquariums, at the Interactive Aquarium of Cancún, you'll get a chance to get up close to sea creatures and even interact with some of them. Here, you can touch starfish and sea urchins, swim with dolphins, or watch them put on a show. There are over 140 species on display here and the Aquarium is open 365 days a year.
