The Todie Canyon trail head is about 3.5 miles south of the Kane Gulch Ranger Station along Utah Highway 261, and then another mile down a dirt road. The BLM charges a $2 fee for day hiking in the Grand Gulch system.
The trail starts out as an easy walk along the canyon rim for about 0.5 miles and then descends very steeply to the canyon bottom. The route is a rocky jumble for about a mile and the going is slow, before smoothing out as it approaches the junction with the Kane Gulch Trail.
The junction is about 7.5 miles along the Kane Gulch trail, so Todie Canyon is a shortcut that allows a day hiker to view this more distant part of the Grand Gulch. There are several pools of water and huge boulders that require the trail to detour away from the canyon bottom for short distances. Take careful note what the route in and out of the canyon looks like as it can be confusing, though it is well marked.
The Split Level Ruin is also not immediately visible from the trail. The alcove is visible but the view is blocked by trees and you’re not sure if anything is there until you explore closer.
It took me 2:30 hours to arrive at Split Level Ruin. I had some trouble on the way back as I tried climbing out at the wrong point. I wasted about an hour and used about 6:00 hours for this 7.6 mile hike. There were very few hikers in this part of Grand Gulch on a 65 F, day in late April.
