Incredible views, very serene. Went in June, bring lots of water. Trail is pretty easy to navigate, occasionally looking for cairns that show the way across the riverbeds (that were dry in June). Beautiful hike that feels like a stroll in the woods.
If you don't have a 4x4 vehicle you can either walk a few miles along the road, or park at chuckwagon trailhead, take chuck to Brinn's mesa TH and turn north on the road there. Then it's only a mile on the road to Secret Canyon TH.
