50 minutes away from Springdale is one of the most accessible and picturesque slot canyons and waterfalls in southern Utah. The creek side trail is fairly short (3.5 miles round-trip) and lies on the easy/moderate scale—little kids will often be seen on the trail here. Be aware that Kanarravile has been “discovered” in the past 5 years and they’re now limiting access to 150 hikers per day. This is a nice little hike and falls. Worth doing.
For the more adventurous: climb the ladder above the first falls, and then hike up to the lesser-visited (but no less impressive) second falls. Permit required and $12 entry fee.
