Upper Oso Campground in Los Padres National Forest offers 24 campsites (approximately 10 equestrian sites with corrals) at 1,040 feet elevation, located about 25 miles north of Santa Barbara near the Santa Ynez River.

The campground provides access to fishing at nearby White Rock Day-Use Area (less than 2 miles away) and swimming in the Santa Ynez River, which is stocked with trout in spring, plus boating and additional fishing opportunities at Cachuma Lake about 10 miles northwest.

Amenities include flush toilets, potable water, fire rings, picnic tables, and firewood for purchase; however, note that winter closures may occur due to high water levels at river crossings, and the campground was recently closed for storm damage recovery through July 2025.
