01
Best overall pick
Diamond Valley Lake Trails
Southeast Of Hemet • Lakeside Trail Network With Open Views • Scenic All-Day Outing
A broad reservoir rimmed with rolling hills and wide-open trails, ideal for longer walks and big-sky views.
The main North Hills and Lakeview trails hug the flanks above Diamond Valley Lake, giving you long sightlines over deep blue water and the San Jacinto range beyond. Expect mostly exposed, gently rolling paths with the occasional steeper pitch, so it’s wise to bring sun protection and extra water. Come on a clear winter or spring day for cooler temperatures and greener hillsides.
02
Closest mountain feel
Simpson Park
Hemet Foothills • Granite Outcrop City Park With Singletrack • Best Nearby Escape
A compact maze of rocky trails above Hemet with surprisingly big views for the short drive from Green Acres.
Perched in the low hills southeast of town, Simpson Park offers a quick hit of boulders, chaparral, and lookouts over the San Jacinto Valley. Short loops fan out from the main parking area, so you can stitch together a mellow stroll or a more rugged workout on rockier singletrack. It’s a handy option when you want real trail underfoot without committing to a full-day drive into the high mountains.
03
Best for wildflowers and wildlife
Santa Rosa Plateau Ecological Reserve
West Of Murrieta • Protected Plateau With Oak Savanna Trails • Best Spring Wildflower Walk
Gently rolling paths cross grasslands, oak woodlands, and seasonal vernal pools that feel a world away from the valley floor.
The Santa Rosa Plateau is known for its broad, easygoing trails that wander through open meadows and shady oaks, with interpretive signs that highlight local plants and history. In late winter and spring, wildflowers and the reserve’s famous vernal pools make the plateau especially photogenic. It’s a great choice for hikers of mixed abilities, with enough mileage to satisfy regular walkers but little in the way of steep climbing.
04
Best high-country escape
Mount San Jacinto State Park (Idyllwild Trails)
Idyllwild High Country • Pine Forest Mountain Trails • Best Summer Cool-Down
Trailheads above Idyllwild lead into tall pines, granite outcrops, and cooler air that feels far removed from the valley heat.
From Humber Park and other local trailheads, you can climb classic routes like Devil’s Slide toward the high interior of Mount San Jacinto State Park. The terrain is steeper and rockier than most lowland walks, but you’re rewarded with shady forest, dramatic boulder fields, and wide views back toward the desert. Leave early, carry layers for changing mountain weather, and treat this as a proper half- or full-day outing.
05
Best quick summit
Mount Rubidoux Park
Downtown Riverside • Urban Hill With Paved And Dirt Routes • Best Short Workout
A short but steady climb on a mix of paved and dirt paths to a historic summit with sweeping city and mountain views.
Mount Rubidoux’s looping routes make it easy to tailor your effort, whether you want a brisk 45-minute power walk or a slower climb with plenty of photo stops. The summit crosses and historic structures give the top a distinctive character, and on clear days you can pick out the San Gabriel, San Bernardino, and San Jacinto ranges. Go early or near sunset for cooler temperatures and easier parking.
