Sourgrass Day Use is a cherished outdoor spot located along the Stanislaus River in Arnold, California. Known primarily as a tranquil day-use area, it offers visitors a peaceful setting for river fishing, picnicking, and light trail exploration. The site’s combination of natural beauty and practical amenities makes it a standout destination for families and outdoor enthusiasts exploring the Central Sierra region. The river here is stocked with trout from early spring through summer, making it a prime fishing destination supported by both stocked rainbow trout and native brown trout populations. However, visitors should be cautious—the Stanislaus River flows swiftly at this spot, which makes it unsuitable and unsafe for swimming. Several signs on site warn of the dangers related to the river’s powerful currents, a sobering reminder of nature’s force.

The day-use area features picnic tables, shaded spots, vault toilets, and a scenic bridge, crafting a comfortable space for relaxing beside the water. Rock paths lead down to sandy riverbanks where you can dip your feet or cast a line. For those interested in exploring beyond the shoreline, a challenging 4x4 off-road trail known as the Sourgrass Trail starts here and caters to vehicles with clearance, adding an element of adventure for off-roading fans.

Visitors often praise the peacefulness of the riverbanks and the easy access to nature without heavy crowds. The cool mountain water and the surrounding pine forest create a refreshing escape during the warmer months. Given these attributes, Sourgrass Day Use has become a popular stop for day-trippers traveling through Arnold or locals seeking a calm natural setting that combines easy fishing, picnicking, and rugged off-road excitement. Overall, the area embodies a genuine outdoor experience shaped by the dynamics of the Stanislaus River and the rugged beauty of the Sierra Nevada foothills.
