The Matias Potrero trail begins just above 1,800 feet on the Arroyo Burro Road. The trail heads east descending at first then slowly climbing as it winds through a series of "potreros" or meadows. At about one mile in you'll reach a high point marked by a large boulder on the left. The next section has twisting and occasionally rocky singletrack. Another short climb takes you to the junction with the Matias Potrero Connector Trail.<br><br>Most people opt for a left at this junction and head north back down to the Santa Ynez River to complete the Matias Potrero Loop. Those who continue east will find a steady climb and worsening trail conditions. Matias Potrero ends at the junction of the Devils Canyon and Tunnel Trails.
