Northeast of St. George and Springdale, the Parus Trail is a paved route along the Virgin River through lower Zion Canyon.
Most mountain bike riders fly into Las Vegas and drive the 2.5 hours to Springdale.
The trailhead starts at the south entrance to the park at the Visitor Center.
While the Parus Trail is only a couple miles long, it leads to the main canyon road which is only used by the Zion Shuttle bus so its perfect to mountain bike ride on the road all the way up to the end at Temple of Sinawava.
Overall, Parus Trail is the 10th most popular mountain bike trail of all 74 mountain biking rides in Utah.
