Nearly 30,000 acres makes this the largest regional park in Maricopa County. Most of the park is made up of the rugged and beautiful White Tank Mountains on the Valleys west side. The range, deeply serrated with ridges and canyons, rises sharply from its base to peak at over 4,000 feet. Infrequent heavy rains cause flash floodwaters to plunge through the canyons and pour onto the plain.
