The Natural History Behind Ontario’s Underground Zoo
From Industrial Past to Wildlife Paradise
What was once a bustling iron ore mine has transformed into one of Ontario’s most fascinating wildlife sanctuaries. After mining operations ceased in the late 1980s, nature began reclaiming these underground spaces in remarkable ways. The abandoned mine’s constant temperature and shelter from extreme weather created perfect conditions for various species to establish their homes.
Similar to other cases of exploring Ontario’s natural formations, the mine’s transformation happened gradually. Bats were among the first residents, finding the cave-like environment ideal for roosting. Soon after, smaller mammals like foxes and raccoons discovered the mine’s entrance chambers made excellent dens.
What makes this site truly special is how the underground ecosystem developed naturally, without human intervention. Groundwater seepage created small pools where amphibians thrive, while mineral deposits form stunning crystalline structures that add to the cave’s otherworldly atmosphere. Today, this accidental sanctuary serves as a reminder of nature’s resilience and ability to adapt, turning what was once an industrial site into a thriving habitat for Ontario’s wildlife.

Meet the Underground Residents
Step into a fascinating world where nature has adapted to life beneath the surface. Here, you’ll encounter remarkable creatures that have made these underground spaces their home. Cave salamanders, with their distinctive pale coloring and slightly translucent skin, are frequent residents, often spotted near water droplets along the tunnel walls.
Look carefully, and you might spot the delicate cave crickets, whose extra-long antennae help them navigate in complete darkness. These resourceful insects play a crucial role in the underground ecosystem by breaking down organic matter that finds its way below ground.
Various species of bats, including the Little Brown Bat and Northern Long-eared Bat, use these underground spaces as winter hibernation spots. During guided tours, you might see them roosting peacefully in ceiling crevices – but don’t worry, they’re sound sleepers!
Perhaps most fascinating are the blind cave fish, which have evolved without eyes in the darkness, and the unique species of spiders that have adapted to life without sunlight. These remarkable creatures remind us of nature’s incredible ability to thrive in even the most unusual environments.
Remember to keep your voice down and avoid touching any wildlife – these are their homes we’re visiting!

Planning Your Underground Wildlife Adventure
Best Times to Visit
Planning your visit to Ontario’s underground wildlife viewing tunnels requires careful timing to maximize your chances of spotting active animals. During spring and early summer (April to June), you’ll witness fascinating courtship behaviors and catch glimpses of newborn animals taking their first steps in the carefully maintained habitats.
Summer months bring extended daylight hours and warmer temperatures, making it an ideal time for families with children. The viewing areas are comfortably climate-controlled year-round, maintaining a steady 15°C (59°F), which provides welcome relief on hot summer days.
Fall presents unique opportunities as many species become more active in preparation for winter. September and October are particularly exciting months when you can observe animals storing food and adapting their behaviors for the coming cold season.
While winter might seem counterintuitive for wildlife watching, it’s actually one of the most magical times to visit. Many animals that are typically shy during warmer months become more visible as they seek warmth in the underground spaces. Early morning (8-10 AM) and late afternoon (3-5 PM) typically offer the best viewing opportunities, as these are peak activity periods for most species.
Pro tip: Book your visit during weekdays to avoid crowds and enjoy a more intimate wildlife viewing experience. Special dawn and dusk tours are available by reservation, offering unique perspectives on nocturnal animal behaviors.
Safety and Equipment Essentials
Before venturing into the underground zoo experience, it’s crucial to come prepared with the right essential safety equipment and follow proper protocols. You’ll need a hard hat, which is non-negotiable and provided by the facility. Wear sturdy, closed-toe boots with good grip – trust me, those underground passages can be slippery!
Bring along a light jacket or sweater, as the temperature stays consistently cool underground, usually around 10-13°C (50-55°F), regardless of the weather above. While the main pathways are well-lit, I always recommend bringing a small flashlight or headlamp as backup – it’s better to have it and not need it!
The facility provides safety briefings before each tour, where experienced guides demonstrate proper underground etiquette and emergency procedures. You’ll learn about designated safe zones, communication signals, and how to move through the tunnels safely.
For photographers, remember that flash photography is permitted but must be used mindfully to avoid disturbing the wildlife. Bring a camera with good low-light capabilities if possible. Keep your belongings in a small backpack that won’t bump against narrow passages.
Pro tip: Leave valuable jewelry at home – rings and necklaces can catch on rock formations. And don’t forget to bring a reusable water bottle; staying hydrated is important, even underground!
