01
Closest summit to the lake
Gavilan Peak
South Of Lake Mathews • Short, Steep Summit Hike • Quick Local Climb With Big Reservoir Views
A brief but punchy hike straight up a rocky hill for wide-open views over Lake Mathews and the surrounding foothills.
From neighborhood streets you gain elevation quickly on rough use paths, so expect loose rock and a noticeable grade rather than a manicured trail. The payoff is a surprisingly expansive panorama of the reservoir, the Santa Ana Mountains, and the Inland Empire without a long drive. Go early or near sunset for cooler temperatures and softer light, and pack your own shade and water since the route is fully exposed.
02
Best canyon network
Sycamore Canyon Wilderness Park
East Riverside • Urban-Edge Canyon Preserve • Best For Varied Loops And Wildflowers
Miles of intersecting dirt paths wind through rocky canyons and rolling hills just a short drive from Lake Mathews.
Sycamore Canyon offers everything from mellow fire-road strolls to more rugged singletrack, so you can tailor the outing to your energy level. Spring brings wildflowers and green slopes, while the rest of the year offers sandstone outcrops, distant city views, and a sense of wildness despite the nearby neighborhoods. Carry a map or GPS app the first time out, as the web of trails can be confusing if you just start wandering.
03
Best riverside wander
Hidden Valley Wildlife Area
Santa Ana River, Northwest Of Lake Mathews • Riverfront Wildlife And Equestrian Park • Best For Relaxed Walks And Birding
Broad dirt trails and sandy paths follow the Santa Ana River through open space frequented by hawks, herons, and horseback riders.
This is the spot to swap steep climbs for easygoing mileage and big-sky river scenery. You can hike short out-and-backs along the bluffs or piece together longer loops on multi-use trails that feel far from the city while still being close to home. Expect limited shade and some soft sand underfoot, and keep an eye out for equestrian traffic when the weather is nice.
04
Iconic local landmark
Mount Rubidoux Park
Near Downtown Riverside • Paved Historic Summit Walk • Best For Sunsets And New Hikers
A gently graded paved road climbs to a historic summit with sweeping views over Riverside, the Santa Ana River, and distant peaks.
Mount Rubidoux is more of a social hike than a wilderness outing, but its reliable pavement and moderate grade make it accessible to a wide range of walkers. From the top, you can wander past stone bridges, a mission-style tower, and old monuments while taking in layered views that stretch back toward Lake Mathews on clear days. Expect crowds on weekends and around sunset, and plan for limited shade along the route.
05
Best full-day option
Lake Perris State Recreation Area
Southeast, Near Perris • State Recreation Area With Summit And Shoreline Trails • Best Mix Of Hiking And Lake Views
Multiple trails, including the popular Terri Peak climb, offer broad views over Lake Perris, nearby mountains, and the Inland Empire.
Lake Perris is a good choice when you want hiking plus a full set of park amenities like restrooms, designated parking, and picnic areas. The Terri Peak route delivers a solid workout on rocky, sometimes exposed singletrack, while easier lakeside paths let you keep things mellow and scenic. Check access and any day-use fees before you go, and bring sun protection—the terrain is classic high-desert scrub with limited tree cover.
