The South Kaibab trail is very short and has some magical views. I hiked the trail during mid November. However, probably better to hike during the spring or fall, when the landscaping is more lively. The trail is pretty short, so I decided to go past the trail and hike all the way down the river/phantom ranch. If you decide to do this, hiking sticks are a must! I saw a new hiker without a stick passed out from exhaustion, which is very dangerous in zero degree temperature. Although it is not recommended to hike to the river and back in one day. It is not too bad if you use sticks, you can hike to the river and back 2x in one day if you're in decent shape. But again, with hiking sticks... It's almost suicide trying to do it without. Back to the trail, if you're bringing family and want a quick trail with great views this is the one. Just be sure to turn back when you see the end sign, or you will be carrying your family back up the canyon ;) Honestly, I enjoyed the south kaibab trail more than the river. When i went past the kaibab trail, it wasn't very pretty, you won't see anything spectacular after the trail just lots of dirt. The river might disappoint some. To describe it, don't expect a "river" when you go down, expect a stream. But it's very quiet and relaxing, and past the river, phantom ranch is a nice reward for the overachiever. To get to the trail, you need to take the south kaibab bus, which runs pretty often, and is easy to access. Not as many people hike this one, so you won't have to push past crowds during the trail.
