Description

Join us as we head to the Duncan escarpment to explore some incredible ‘crevice’ or ‘fracture’ caves, created over thousands of years through a mixture of glacial movement, extreme temperatures and the raw force of gravity. 

We start the hike through open farmland and meadow before the ground tilts up and we climb onto the escarpment itself. From there, most of the day is spent walking along the escarpment and through the forest that grows right up to the cliff edge and spill over its exposed rock.

We will then descend into the caves, with some being over 30 metres deep. You will be scrambling in some places, working your way down and through one of the more unique pieces of trail anywhere in Ontario.

From the caves, the trail climbs back along the escarpment edge through mature forest, with a stretch of cliff top that opens up into views out over the valley below. We drop back down and loop through the same mix of field and forest that opened the day.

Parking is extremely limited at the trailhead, so we recommend taking transport for this adventure.

What to Expect on a WU Trip

Is a Wilderness Union Trip Right for You?
We offer a unique alternative to commercial tours. We don't just show you incredible natural wonders, we teach you to become confident in nature so you can discover the life changing magic of the outdoors. You'll love it here if:
- You want to make real friends, not just small talk with strangers
- You prefer "off the beaten path" over "all-inclusive resort"
- You're happy to pitch in and learn new skills (e.g., helping with camp setup or group tasks)
- You value the journey and the company as much as the destination

Who Else Will Be There
WU is aimed at a younger generation of outdoor lovers who don't see themselves represented in traditional hiking clubs and our members are typically 20-40 years old. Whether you're brand new to the outdoors or have plenty of experience, you'll find something for you.

Our Guides
All of our guides are highly qualified, passionate outdoor lovers, just like you. They love to share their knowledge and will help you see our destinations in another light, often teaching you something along the trail.
