Intermediate Hikes in Inland Empire
The Inland Empire sits at the edge of several distinct wilderness zones — the San Bernardino Mountains, the Santa Rosa Plateau, and the Box Springs range — giving intermediate hikers a surprisingly deep bench of trails to explore. These routes push beyond easy nature walks without demanding technical skills or extreme fitness, typically running 5 to 10 miles with moderate elevation gain. Whether you're building toward bigger peaks or just want a satisfying half-day effort, this region delivers year-round.
10 intermediate hikes in Inland Empire
A long but non-technical out-and-back with sustained switchbacks that reward hikers with panoramic views of the LA Basin and San Gabriel Valley — ideal for intermediate hikers ready to test their endurance.
This shaded canyon route through the San Gabriel Mountains provides consistent climbing on a well-maintained trail, making it a satisfying challenge without exposed scrambling.
The lower portion of this classic peak route offers dense forest, reliable stream crossings, and enough elevation to feel earned — a perfect intermediate target before attempting the full summit.
Vivian Creek's lower section features lush riparian scenery and steady elevation gain through the San Bernardino National Forest, giving intermediate hikers a genuine mountain feel without the summit's exposed final push.
Low elevation gain makes this Murrieta-area loop more about distance and endurance than climbing, with oak woodland and vernal pools offering scenery that rewards a comfortable, sustained pace.
Located minutes from Riverside, this ridge loop provides city-fringe hiking with surprisingly open views and enough rocky terrain to make footwork interesting for intermediate hikers.
A steady climb through ponderosa pine to a historic fire lookout tower above Lake Arrowhead — short enough for a quick hit but with enough gain to require consistent effort.
This Big Bear area route combines forest exploration with a rolling ridgeline and visits one of California's largest lodgepole pines, keeping intermediate hikers engaged with varied terrain.
Starting near Big Bear Lake, this trail climbs through open chaparral and Jeffrey pine to a summit with sweeping desert and mountain views — a well-calibrated intermediate effort with a clear payoff.
Yucaipa's Crafton Hills offer a network of connector trails with rolling terrain and scrubland views of the San Gorgonio Wilderness, giving intermediate hikers flexible route options close to the eastern Inland Empire.
What Makes a Hike 'Intermediate' in the Inland Empire.
Intermediate trails in this region generally fall between 5 and 12 miles round-trip with elevation gains in the 800 to 3,000 foot range, and they may include sustained switchbacks, exposed ridgelines, or seasonal creek crossings. Unlike beginner routes, they demand pacing strategy — you can't power-hike the first third and expect to have legs for the descent. The Inland Empire's elevation variation also means intermediate here spans everything from a rolling 9-mile plateau traverse at 2,000 feet on the Santa Rosa Plateau to a lung-testing climb approaching 8,000 feet near Big Bear. Knowing where your fitness sits within that range helps you choose the right objective for any given weekend.
Seasonal Conditions and When to Go.
Lower-elevation routes like Box Springs and Santa Rosa Plateau are best hiked from October through April, when desert heat is manageable and wildflowers peak in late February and March. Mountain routes near Big Bear and Lake Arrowhead are accessible May through November but can hold snow on north-facing slopes well into spring — always check road and trail conditions before heading up Highway 18 or Highway 138. Summer hiking in the San Bernardino Mountains is comfortable above 6,500 feet, often 15 to 20 degrees cooler than the valley floor, but afternoon thunderstorms develop quickly in July and August, so start before 7 a.m. and plan to be off exposed ridgelines by midday.
Group Hiking Safety on Inland Empire Trails.
Cell service is unreliable on many San Bernardino National Forest trails, including stretches of Vivian Creek and the upper Icehouse Canyon approach. Hiking with at least two other people means someone can stay with an injured hiker while another goes for help — a scenario that matters more on remote intermediate routes than it does on a crowded nature walk. Let a non-hiking contact know your planned trailhead, target turnaround time, and expected return. On permit-access trails and busy weekends, parking lots fill before 8 a.m. at popular Inland Empire trailheads, so carpooling with a group is both practical and a buffer against starting solo by default.
Fitness tips for intermediate hikers
- Build a base of three to four hikes per month on shorter, flatter trails before committing to sustained climbs above 2,000 feet of elevation gain.
- Practice hiking with a loaded daypack — 15 to 20 pounds — at least once before tackling longer intermediate routes, since carrying water and layers changes your energy output significantly.
- Train on stairs or inclined treadmill sessions to prepare your calves and hip flexors for the repeated uphill demands of San Bernardino Mountain trails.
- Schedule a rest day after any hike exceeding 8 miles or 2,500 feet of gain to allow connective tissue recovery, which lags behind cardiovascular fitness for most hikers.
- On warm-season Inland Empire hikes, plan to consume at least half a liter of water per hour of active hiking and eat a small snack every 90 minutes to maintain steady energy on longer climbs.
Recommended gear
- Trail runners or low-cut hiking shoes with a sticky rubber outsole work well on the region's mix of packed dirt, loose granite, and pine needle paths — reserve stiff boots for routes with significant rock scrambling.
- A 20 to 25 liter daypack with a hip belt distributes weight efficiently on 5 to 10 mile routes and leaves room for layers, which are essential in the San Bernardino Mountains where temperatures drop quickly after noon.
- Trekking poles reduce knee stress on steep descents — particularly valuable on trails like Icehouse Canyon and Vivian Creek where you lose elevation quickly on the return leg.
- Carry a basic navigation tool: a downloaded offline map via a phone app or a printed topo ensures you stay oriented on multi-junction trail networks like Crafton Hills or Santa Rosa Plateau.
- Sun protection is non-negotiable in the Inland Empire — a UPF 50 long-sleeve shirt, broad-brim hat, and SPF 50 sunscreen prevent overheating and sunburn on exposed ridge and plateau routes.
