There are only superlatives to express the experience taking in the Othello tunnels and its canyon. No one leaves this area unimpressed. The loop allows one to take a trail, once part of the Brigade Trail, above the tunnel area. Expect the latter to be a rugged trail and requiring quite a bit of climbing. Of course the trail through the tunnels was once a railroad and therefore the grade is less than two percent. The distance may seem short but because of the climbing it will take extra time. Allow 2.5 to 3 hours.
