If you're looking for a unique adventure, consider hiking to the Abyss. This striking 50cm wide fissure is located on a ridge above the city of Nanaimo. The cause of the land split remains a mystery. Some say it was caused by a collapsed mine tunnel or earthquake.
The 1km uphill hike is well-signed and passes through a beautiful grove of arbutus trees (as well as an ugly cut block). Please keep dogs on a tight leash - I've heard about dogs falling into the crack and having to be rescued.
