The park's marquee hike: an easy first mile, then a steep, rocky climb to a chain of desert pools, about 4 hours round trip. The trail continues to Romero Pass at 6,000 feet, a strenuous 10-hour day. Dogs and bikes stay below the wilderness gate.

The park's signature loop, linking the Romero and Sutherland trails through desert riparian pockets of sycamore and ash. A few stairs and short climbs; seasonal water crossings after rain.

Known for spring wildflowers and seasonal water at Dripping Springs. The first 2.6 miles are an easy valley walk; beyond, a rocky ascent climbs Cargodera Canyon to meet the Mt. Lemmon Trail, 9.9 miles one way. Dogs and bikes stay below the bighorn management area.

A quieter loop from the Romero Ruins lot through mesquite forest and desert grassland, with dramatic mountain views, springtime wildflowers, and seasonal waterfalls.

A short interpretive loop over an ancient Hohokam village site from around 500 AD and the late-1800s Romero homestead. A few stairs; no bikes or horses.

An educational loop with a short, steep climb into a saguaro hillside, then gentle foothills. Signs cover the desert's plants, wildlife, peaks, and geology.

A signed loop through mesquite bosque, desert, and riparian habitat. The park is home to over 150 bird species; educational signs point out who to look for.

A flat, shaded connector between the main trailhead and the equestrian center, 1.4 miles each way. Compacted tread that works for strollers, wheelchairs, and bikes.

A peaceful ridge through pristine cactus forest with outstanding views over Oro Valley. Branch off the 50-Year Trail and reconnect for a 3.2-mile loop.

The equestrian and mountain-bike favorite, from the equestrian center through giant saguaros for 2.4 miles to the park boundary, then north through desert grasslands. Rocky, technical stretches for riders.

A rocky, lightly maintained connector between the Sutherland and 50-Year trails with long mountain views and no shade. Bring navigation; combining all three makes an 8.8-mile loop.
