The San Gabriel Mountains tent camping options near San Marino, California range in elevation from approximately 2,000 to 5,000 feet. Stream flow varies dramatically by season, with peak water levels occurring from January through May following winter rains. Trail camps in this region typically receive fewer visitors on weekdays, with busiest periods occurring during spring and early summer.
What to do
Hike to waterfalls: The trail from Bear Canyon Campground connects to multiple cascades. "Crossing the tiny bridge at the west end of Switzer Picinic area, you snake up the hill and see breathtaking views from the top of the canyon. Follow the creek (which is GORGEOUS with waterfalls and shade in the spring)," shares one camper.
Backcountry fishing: At Glenn Trail Camp Campground, the nearby stream provides fishing opportunities. "This area is native to good trout fishin'," according to a reviewer. The road to the campground follows a river the entire way with fishing platforms along the route.
Historical exploration: Several trails feature remains of old mountain resorts. At Idlehour Trail Camp, you can find "old fashion wood burning stoves" from earlier eras. The camp sits near a flowing creek with "a 10 foot waterfall just 50 yards away," making it a destination with both historical and natural features.
What campers like
Creek access: Almost every trail camp in the area sits near seasonal water sources. At West Fork Trail Campground, campers appreciate the proximity to water. "The sites are right along the creek and very peaceful. You do have to hike out your own water or filter from the stream," notes one visitor. Another mentions, "Plenty of water flowing and tree cover from the sun."
Wildlife viewing: Morning animal sightings frequently occur at these secluded camps. "I have woke in the morning to deer on several occasions," reports a West Fork camper. Bear boxes at some locations indicate the presence of larger wildlife, requiring proper food storage.
Seclusion despite proximity: Hoegees Trail Camp Campground offers wilderness immersion despite being relatively close to urban areas. "The Big Santa Anita Canyon Loop on Mount Wilson offers dog friendly free camping immersed in thick mountain woods with babbling creeks and numerous waterfalls," writes one reviewer. Another adds it "feels completely isolated" despite the short hiking distance.
What you should know
Seasonal water reliability: Creek flow varies dramatically throughout the year. A camper at Spruce Grove Trail Campground notes, "I go in March/April so the stream has plenty of water to drink." Many creeks maintain flow through early summer but diminish by late season.
Security concerns at trailheads: Vehicle break-ins occur at some parking areas. "Make sure to leave your car doors unlocked, and nothing of value inside. You'd rather have someone root through your car and walk away empty handed than have a window broken and items stolen," warns a Millard Trail camper.
Variable toilet facilities: Bathroom options differ widely between camps. One camper at Idlehour Trail Camp states bluntly: "There are no tables, just some old fashion wood burning stoves. No toilet." Even when toilets exist, maintenance may be inconsistent.
Challenging terrain: Many trail camps require significant elevation gain on return hikes. A West Fork camper cautions, "It is a challenging hike if you have a heavy pack. However, there is a utility road you can take that would make it 100% easier."
Tips for camping with families
Starter backpacking destination: Several locations offer perfect introductions to wilderness camping. "Valley Forge Trail Camp is great for families. "Took some friends for their first ever backpacking trip, great intro to the 'experience.' Trail camp is in the canyon so it's an easy 3.5 mile hike in, but a tough hike out of the canyon," explains one camper.
Water crossings add fun: Seasonal streams create natural play areas. "In April the creek was full, with several creek crossings on the hike and crisp, fresh water along the campsite that contribute to a beautifully green owasis of a meadow," reports a Valley Forge visitor.
Distance considerations: Select camps based on children's hiking abilities. Gould Mesa Trail Campground offers a manageable approach: "This is about a 15 minute drive then 30 minute hike from my house," notes one camper, making it practical for families with younger children.
Tips from RVers
No direct RV access: All trail camps in the San Gabriel Mountains require hiking to reach tent sites. For RVers willing to temporarily leave their vehicles, Millard Trail Campground offers relatively easy access: "The parking lot is just behind the corner out of view," making it possible to camp without seeing your vehicle while maintaining proximity.
Parking size limitations: Most trailheads have restricted space. At Millard, "Parking is about 150 yards away, down a hill, so be prepared to haul your gear." Another camper notes the small lot "fits about 20 cars," requiring early arrival on busy days.
