Overview Pine Flat picnic sites A & B are accessible picnic areas. They are located on State Highway 337 (James McGrane Memorial Highway or Old South 14) approximately 7 miles from I-40. State Hwy 337 runs parallel to Pine Flat picnic area making it easy to identify and enter. From the entry way to your left you will find two reserve only sites. The area is surrounded by pinon, juniper, scrub oak and ponderosa pine that lend shade to both reservation areas. Cool mountain breezes are common here. The sound of rustling foliage render Pine Flat picnic sites an excellent place to lean back, relax and maybe even take a nap. Each site can accommodate fifty people. Pine Flat Trailhead has pull through trailer parking in addition to regular vehicle parking, which is located to the right as you enter the gate. Follow the road south to the trailhead that leads into the Manzanita Mountains Trail system. You will also find dispersed picnic tables throughout the Pine Flat sites, which are available on a first-come, first-served basis. Pine Flat Sites A & B were built in 1956 by the Forest Service with the intent to provide picnic sites for large group use.
