Located near the meeting of the Gila and Agua Fria Rivers in the southwest Valley, the park includes seasonal wetland or riparian area during our winter and monsoon rains. The majority of the park remains pristine desert, very similar in appearance to the landscape seen by the first settlers and explorers. The Sierra Estrella range, or Star Mountains, was once within the Mexican border, and remained so until the Gadsden Purchase in 1853. Today, many amenities are available to visitors, including the only grass picnic area (65-acres) in the Maricopa County Park System.
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. These torrential flows, pouring down chutes and dropping off ledges, have scoured out a series of depressions, or tanks, in the white granite rock below, thus giving the mountains their name.
The Japanese Friendship Garden of Phoenix, RoHoEn is an authentic 3.5 acre Japanese Stroll Garden with a tea garden and a tea house. This tranquil and beautiful setting features more than 1,500 tons of hand-picked rock, stone foot bridges, lanterns and more than 50 varieties of plants. As you stroll the path, you will enjoy flowing streams, a 12-foot waterfall, and a Koi pond with over 300 colorful Koi fish.
