4 Mount Nimbus, Canada
One of the best mountain trails that enable amateur adventure seekers to climb a mountain as the climb includes a safety harness attached to the iron rungs along the mountain. But it also takes nerves of steel to take the challenge and climb up to Mount Nimbus.
5 Cliffs of Moher
Located in the Burren region of Claire county Ireland, this is definitely not an activity for amateurs. Even the image is enough to explain everything. Truly one of the most terrifying tourist locations in the world.
