Rainbow is the largest campground in the Big Lake Recreation Area in eastern Arizona. Because of its proximity to the lake, size and the many amenities it offers, Rainbow is a favorite for families. Popular activities include hiking, horseback riding and fishing.
The campground is adjacent to 450-acre Big Lake, one of Arizona's top fishing lakes. The lake is known for its trout fishing, with rainbow, cutthroat, brook and Apache being the most sought-after species.
The recreation area is also popular for hiking, mountain biking, birding and wildlife viewing. Curious campers can attend educational programs at the recreation area's visitor center.
The facility boasts 165 campsites organized into six loops. Four double sites are available for up to 16 people each, which is convenient for larger families, and two single unit accessible sites are also available.
A small store nearby sells gas, food, boat rentals and firewood. A campground host is available on-site for visitor assistance.
Rainbow Campground sits at an elevation of 9,000 feet in the White Mountains. It is a very scenic area, forested with ponderosa pine, Douglas fir, spruce and aspen trees, which provide ample shade.
Summer temperatures are pleasant and cool, a nice respite from the heat of the lower desert. Visitors should come prepared for cool nighttime temperatures and occasional summer thunderstorms.
Visitors can explore endless vistas and take part in many outdoor activities in the surrounding Apache-Sitgreaves National Forest, which encompasses 2 million acres of magnificent mountain country in east-central Arizona and New Mexico. Springerville, Arizona is the closest town to the campground.
From Pinetop, Arizona, take Highway 260 east 25 miles to Highway 273 south. Follow Highway 273 south 19 miles to Forest Road 8115 (Big Lake Entrance). Turn right and travel 1 mile to the campground.
