Saint George Mx is a pretty good track, mid week at mesquite mx you can have the track to yourself! Iron mine in cedar is never open.
Coral pink sand dunes is outside of Hurricane and has some really fun two track sand trails with lots of turns with great berms and whoops. Plus with the pinks you get to drive by Colorado city and Hillsdale (crazy weird polygamist towns). Lots of good single track out in Warner Valley and toquerville falls has one of my favorite single tracks! It also has route you can drive a 4x4 to get to a kick ass waterfall, I ride out and meet my fam at the falls. It's a fun spot we swim and snag lunch there at least 4 or 5 times a summer. Duck creek is geared towards side x sides and quads. Rent a rzr and check out mammoth cave and strawberry point.
