This trail is within the city of Nanaimo. The Ultimate Abyss takes its name from a huge fissure in the volcanic rock making up the ridge on which the trail travels. High above the Harewood Plains, the trail repeatedly crosses over this 10-20 cm (8-11 inches) opening. Mixing a high level of technical challenge with some exquisite views, this 4.72 km (2.83 miles) one-way ride offers equal potential as a quiet hike
