One of the best trails to hike in Zion’s Kolob Canyon is Middle Fork Taylor Creek Trail. It’s a 5mi (total) out and back trail that’s 2 miles from the visitor center (1st parking lot on the left). It features a river/creek (depending on the season) and is rated as moderate. The trail is accessible year-round and most people hike 2.5mi to the Double Alcove. The beginning of the hike is open (unshaded) with a gradual increase in elevation and great views of the surrounding shear peaks. Further along the trail, you hike between the cliff faces shaded, following a dry river bed. It’s a fairly wide canyon so this is not slot canyon hiking. You do not get surrounded by rock faces like other hiking trails or have flash flooding concerns. Hiking 2.5mi in has a 590ft elevation gain, till you reach the Double Alcove. This is a great spot for photos and lunch. It was not crowded (~8 people) when we were there since we got an early start (when it was cooler). But as we were walking back around noon, there were more people on the trail heading in. Still, this area is significantly less crowded than the trails in Zion Canyon. We bumped into park volunteer John on the trail & he mentioned the lesser known South Fork Trail. He said it was an even better hike since you hike against the cliff and it narrows into a slot canyon. It’s shorter (3mi total) & more challenging, with 1070ft elevation gain on a less maintained trail. We’ll do that tomorrow.
