A fun little stop for the whole family south of Mt Carmel Junction on highway 89 in Utah, is the Belly of the Dragon. It is a man made culvert under the road, made to drain water during rainstorms, nothing more than that but still a fun stop.

There is parking at the western end of the tunnel. The entrance to the tunnel can be a bit tricky, since the most logical entrance is via the spillway but that stops at a 10 feet vertical drop where the tunnel starts. You need to hold to the left side of the bank and slide down the side of the spillway and into the tunnel. We would recommend sturdy shoes, it might be slippery.

Inside the tunnel gets quite dark, we managed fine with our Iphone flashlights. The walk itself is just 1-2 minutes, and there is a small ledge halfway in that you have to climb. At the other end of the tunnel there is a trailhead for those who want to walk a bit further into the wilderness. Not a must stop but a nice stop on Highway 89 towards Kanab.
