A year or two ago, we actually cycled the Othello Tunnels. They are in Coquihalla Canyon Provincial Park. They are there, because there was a train line. It got abandoned, because it was too hard to maintain, it was costing too much money. Then it got transformed into a set of cycling and walking trails. In May of 1986 it was made a recreation area. This picture is from our trip, taken from the path between two of the tunnels.
This is interesting, Cole - and your second "visit"! I didn't know about them even though we travelled very nearby many times.
