Tunnel Bluffs is a 4.6-mile out-and-back trail located in Lions Bay, British Columbia. It has an elevation gain of 2,244 ft and offers stunning panoramic views of Howe Sound, Bowen Island, Horseshoe Bay, and Vancouver Island. The trail is popular for hiking and running but remains pleasantly uncrowded compared to other trails in the area. With wildflowers dotting its path and wildlife sightings, this trail is the perfect way to experience nature's beauty at its fullest. The first section follows a rocky service road with sharp elevation gain, but after that the trail evens out and becomes more pleasant. Dogs are welcome, though they must be on a leash.
