01
Best overall pick
Peters Canyon Regional Park
Foothills East Of North Tustin • Open-Slope Reservoir Park • Local Favorite For All Levels
A close-to-town network of loops with lake views, rolling hills, and options for both casual walks and leg-burning climbs.
Peters Canyon is the go-to choice when you want dirt under your shoes without a long drive. The popular Lake View and East Ridge loops give you a mix of wide fire roads, singletrack, and big-sky vistas over the reservoir and surrounding suburbs. Expect some exposed climbs, so go early on hot days and bring extra water.
02
Best for variety
Santiago Oaks Regional Park
Hills Above The City Of Orange • Shaded Creek Canyon Network • Best For Mix-And-Match Loops
A laced-together system of creekside paths and hill climbs where you can tailor the route to your mood and fitness.
Santiago Oaks offers a surprisingly wild feel just a short hop from North Tustin, with oak-shaded gullies, chaparral hillsides, and rocky viewpoints. Shorter loops near the creek are great on warm afternoons, while routes up to Robbers Roost or Barham Ridge reward you with big views toward the Santa Anas and the basin. It is an excellent spot to explore different combinations until you find a personal favorite circuit.
03
Best wild-feeling escape
Limestone Canyon Nature Preserve
Santa Ana Mountains Foothills Inland • Protected Wild Canyon Preserve • Best For Guided Nature Outings
A more remote preserve known for The Sinks, a sandstone cliff amphitheater that feels far from suburban Orange County.
When access days line up, Limestone Canyon delivers one of the most scenic hikes in the region, with quiet trails and a genuine backcountry vibe. The route out to The Sinks follows broad ranch roads through grasslands and into a canyon, ending at a dramatic overlook into the sandstone formation. Plan ahead for limited open-access or docent-led days, and give yourself time to linger at the viewpoints and interpretive signs.
04
Best for a challenge
Black Star Canyon
Remote Canyon Northeast Of North Tustin • Rugged Backcountry-Style Canyon • Top Pick For Adventurous Hikers
A tougher out-and-back that starts mellow but becomes a rock-hopping scramble to seasonal falls and a narrow canyon.
Black Star Canyon is a rite of passage for many local hikers, thanks to its mix of history, scenery, and effort. The early miles on the dirt road feel straightforward, but once you leave the main track the route turns into a boulder-filled creekbed with uneven footing and brush. Go with sturdy shoes, allow extra time, and be ready to turn around if water is too high or the scramble feels beyond your comfort level.
05
Best rolling ridge hike
Weir Canyon Wilderness Park
Along The Anaheim Hills Ridgeline • Open Ridge And Oak Woodland Corridor • Best Sunrise And Training Loop
A scenic loop that strings together ridges and canyons, offering broad views and steady climbs without technical terrain.
Weir Canyon is ideal when you want a solid workout and big horizons but prefer smoother trails over rock scrambles. The main loop climbs onto open ridgelines where, on clear days, you can trace the curve of the Santa Ana Mountains and look back over the neighborhoods of North Tustin and beyond. In spring the hillsides often glow green with wildflowers, and in cooler months it is a pleasant spot for brisk early morning laps.
