Catalina State Park — Romero Pools, the Canyon Loop & Sutherland Wash

On the far northwest flank of the Santa Catalina Mountains — a wholly different door into the range than Sabino Canyon or the Mount Lemmon Highway — Catalina State Park spreads across 5,500 acres of saguaro-studded foothills where two desert washes drain out of the high country. It is a hiker's park first and foremost: the marquee outing is the Romero Canyon Trail, which climbs from the desert into a hidden string of granite-lined pools that hold water for much of the year, a genuine oasis rimmed by cottonwood and sycamore. Gentler options abound — the flat, family-friendly Canyon Loop stitches the trailheads together through classic Sonoran desert, and the broad Sutherland Wash carries you toward ancient Hohokam petroglyphs and long views up to the Catalina crest. Ten minutes of good restaurants in Oro Valley sit just outside the gate.
