Add Some Fun. While the normal route into The Subway is often called the "Russell Gulch Approach", it actually only crosses Russell Gulch rather than descending it. This variation descends the canyon with three rappels of 100 feet (30 m), adding a little technical interest and another nice section of canyon to the normal Subway Route.
This alternate approach adds about an hour to the route, for small groups. While the route is fairly straightforward, the rappels themselves have awkward starts and are not suitable for beginners.
Russell Gulch requires an additional permit to your Subway permit, has a group size limit of 6 and a daily quota of 12.
