This will probably be my last hike here in Utah, at least for this year. It was close by, just a short drive from the RV. I might have walked or ridden a bike to the trailhead if I’d known about their pricing. It’s $10 per vehicle, up to 8 people but only $4 per person if you walk or ride in. AllTrails listed this one as moderate to strenuous. There’s several hundred feet of elevation changes. At the start of the trail that’s done via switchback trails. If you do the optional Sleeping Rainbow loop, those ups and downs are more straight forward. BTW, that loop had pieces of petrified wood scattered all over the place. Just out of curiosity, I picked a piece up and it was surprisingly heavy.
