Tanner Trail is a 13.6 mile lightly trafficked out and back trail located near Grand Canyon, Arizona that features a river and is only recommended for very experienced adventurers. The trail is primarily used for hiking, trail running, camping, and backpacking and is best used from March until November.
A rigorous rim-to-river backpack of three or more days, following one of the South Rim's more difficult trails. The unmaintained trail, recommended only for seasoned hikers, is relentlessly steep, rocky, shadeless, and waterless until you reach the Colorado river. The tread is well worn and generally easy to follow, and the route offers access in one long day to one of the most scenic beach campsites in the canyon.
Hiked on our way in before continuing on the Escalante Route and finally up Grandview Trail. The Tanner is an excellent trail and very easy to follow. I would still bring a map and pay attention to the topography as other unnamed trails spur off at points however it is clear which is the main trail. Great views the entire was to the Colorado.
Excellent trail. Do not attempt if unprepared. Many parts of the trail are difficult to follow to the inexperienced. Weather can change drastically because of the elevation changes and the topography. You go approximately half a mile down into the hot canyon (desert) from a snowy rim. The vistas are bewitching, the evenings and sunsets are spectacular and exotic. A full moon from inside the Canyon, setting over the buttes or the rim will leave an indelible mark in your memory and your heart. Plan carefully and make sure that you are light enough on the way out, you will have to climb that same route back without running out of water. Therefore strongly consider caching (hiding) water on the way out. If you needed me to clarify caching, you probably will need help someone to help you on this one. Do not attempt alone, unless you are very experienced AND prepared. You will traverse portions of the trail fully exposed to cliffs that may land you on the river, with a narrow trail slanting outwards. You will exert yourself physically on the way out and look at the beauty around you to incessantly remind you: that's why I chose to do this, isn't it?
Tough but excellent backpacking trip. Camping by the Colorado river is beautiful and the scenery on the entire trip was amazing! We spent one night on the trail on the way down to the river, two nights at the river, and one night on the trail on the way back to the rim. There is no water anywhere on the trail other than the river, and it is very silty. A good filtration system is a must.
