Marysvale and The PAIUTE ATV TRAIL. The Paiute ATV Trail surrounds Marysvale, making this the best place on the trail to set up camp, and explore in every direction. The trail is 275 miles long so we suggest that you do it in segments and the best way to see it all is from Marysvale (Really!). Best esimates are that it would take 25 hours to ride the entire loop, without much time for pictures.
