Hike or run past oak forests, vernal pools, rock climbing walls, and fields of chaparral on this 9-mile out-and-back to the Santa Ynez Ridge.

The first half of the 4.5-mile-long San Ysidro Trail samples all the classic Santa Barbara frontcountry features: lush deciduous forest, jagged rock walls frequented by altitude-crazy climbers, secluded waterfalls peppered with swimming holes, and vernal pools under canyon shade.
While most stop at the waterfall 1.6 miles in, the best views are further ahead. The route traverses chaparral meadows along the base of Montecito Peak, gaining nearly 2,000 feet in 3 miles on a lung-searing stretch for trail runners. Follow the switchbacks to colorful high country vegetation and views of snow-capped summits at Santa Ynez Ridge. When finished, retrace your steps back to the trailhead.

Reach another great pool with a tall waterfall and a lot of lush vegetation. There's also an impressive sandstone formation here: a narrow rib juts out of the canyon on the other side of the creek. Head northwest up a rocky sandstone trail that switchbacks into sweeping chaparral vistas.
