The open face of a small cave and rock benches and tables await you in the deep shade in McKittrick Canyon, a tempting location for a picnic. Follow the trail from the Grotto to Hunter Cabin, a structure which was once part of a hunting retreat and ranching operation. Look up the canyon slope and see the steep switchbacks where the trail continues to the Notch and onto McKittrick Ridge. Round-trip distance from the visitor center to the Grotto is 7.0 miles.
