Took my son to see Hozier last summer. It was both our first time at the rocks and it awesome. We drove down from Laramie, parking was fine, had to walk a bit but nothing to complain about, almost got in the bathroom line thinking it was the line to get into the venue (close call), I drank some...
We did, most of it anyway. The river was high and the road was flooded at Taylor Canyon, so we drove in and out from Schafer road. Stayed at Gooseberry and Candlestick.
My sheep picture sucks compared to yours.
There a lot of trails down there, of varying difficulty. My favorite is Kane Creek Canyon, but it has gotten harder over the years. Fins and Things is fun. Definitely hit Mini Lions back. We drove the White Rim road last year. Not hard, but scenic.
Second Canyonlands, although I like the Needles district a lot. It's a bit further south. What kind of off-roading are you doing? We spent a few spring breaks down there in college jeeping. Great fun.
