Train tours of Canada provide a great way to take in all of the natural beauty that the Great White North is known for. Travelers who wish to learn even more about the world that surrounds them may not think to look in Montreal, Canada’s second-largest city.

However, this is exactly where they will find a number of scientific attractions designed to expand visitors’ knowledge of Canada’s ecosystems. Here are two possible destinations for train passengers making a stop in the city:

Montreal Biodome

When travelers on Canadian rail trips make their way to the Montreal Biodome, they are in for a couple of treats. Not only do they get to learn about the natural world, but they also get to explore a space that was built for the 1976 Summer Olympics. The structure, which sits below the futuristic Olympic Tower, originally served as a venue for track cycling and judo events.

Today, visitors to the facility are more likely to bump into a penguin than an Olympic athlete, as the space has received a total makeover to accommodate the various ecosystems that can be found throughout the Americas.

A number of penguins can be found in the Biodome’s Sub-Antarctic Islands exhibit, which, according to the attraction’s website, offers travelers a peek at life on the tip of South America. Here, visitors can view four different penguin species: rockhopper, gentoo, macaroni and king penguins.

After braving the frigid elements of the Sub-Antarctic Islands, individuals can warm up with a walk through the Biodome’s Tropical Rainforest exhibit. Along the way, they may spot a two-toed sloth climbing a tree overhead or hear multiple parrots conversing with one another.

Montreal Insectarium

While very few people dislike penguins, insects are more of an acquired taste. As a result, only the most adventurous of travelers will want to swing by the Montreal Insectarium. If travelers would like to visit this attraction and the Biodome, they will be happy to learn the two destinations are located right near one another.

Nature lovers may have always been fascinated by honeybees, but too afraid to get a closer look at what they are doing. Visitors to the Insectarium can let go of those fears and learn everything they ever wanted to know at the institution’s two glass-walled colonies.

According to the Insectarium’s website, travelers can also see how bugs are just as comfortable in the water as they are on land and in the air. The attraction’s aquarium is home to everything from giant water bugs to fishing spiders.
