Chino Hills State Park

Chino Hills State Park is a large,14,000 acre park, located in the northeast corner of Orange County.  There are three primary entrances to the park.  The western entrance is via the newly opened Discovery Center (immediately east of Carbon Canyon Regional Park), the southern entrance off Quarter Chino Hills State ParkHorse Drive in Yorba Linda, and the main park entrance located in the northwest corner, off of Highway 71, in Chino Hills.  HOWEVER, due to construction (or lack thereof), the road within the park, Bane Canyon Road, is closed!  Visitors using this entrance will need to park outside the park along Sapphire Road.  Click here for updates regarding this entrance.

Wildfires back in 2008 scorched 90% of the park and evidence of those fires is still quite prevalent.  Many of the hills are bare and there is virtually no shade along the 90 miles of trails within the park.  Having said that, vegetation is making a remarkaBikersble comeback, and the park still offers a unique opportunity to escape the congestion of Orange County and surrounding communities.  The vast size of the park allows users to explore a territory rich in rolling hills, canyons and grasslands.  Because of the road closure of Bane Canyon Road, the campground is also closed...as a result, the northern end of the park has a remote, deserted appeal to it.

Of all the parks in this guide, Chino Hills State Park slants heavily in favor of mountain bikers.  The remoteness of the park, the temporary closure of the  campground, and the complete absence of shade deter runners and hikers ... but for mountain bikers there are trails galore.  Everything from flat, wide-open fire-roads to ball-busting single-track.

The Rangers Stations provide a very good maps of the park, a comprehensive map as seen below, and four additional maps covering each quadrant of the park (to view these maps see the alternative maps links below):

Trails and Map


Gilman Peak Loop and Beyond (10.8 miles)
-- This moderate, but long course starts at the very western edge of the park at the newly opened Chino Hills State Park Discovery Center (just east of Carbon Canyon Regional Park).  Begin by heading east along the gravel Telegraph North Ridge TrailRoad until you reach the sign for the North Ridge Trail.  This begins the gradual ascent towards Gilman Peak (elevation of 1,685').  North Ridge Trail primarily traverses the Gilman Peaknorthern side of the ridge with occasional glimpses of the southern slope and Telegraph Canyon.  The trail is fairly wide (but not exactly fire-road), in great shape, and the climb is gradual but consistent.  Over the course of 3.6 miles you'll climb close to 1,100'.  When you reach Gilman Trail, take the short jaunt (less than a quarter mile) over to Gilman Peak.  The peak is quite anti-climatic with nothing more than a broken marker to let you know you've made it.  From here you have the option of returning Sycamore Trailvia Gilman Trail (closed to bikers) or continuing along North Ridge Trail.  We'll take the later and get in some extra mileage.  Backtrack down to North Ridge Trail and continue east for another mile until you reach Sycamore Trail and begin your descent to Telegraph Canyon.  Sycamore Trail is a wide-open fire-road that pleasantly winds its way down the hill.  The terrain is grasslands with a few surviving trees scattered about.  The southern slope seems to have Telegraphsuffered (2008 fire) much more extensively than the opposing northern slope which is dotted with trees. When you reach the bottom after 1.2 miles you'll be connected to Telegraph Canyon Trail where you'll turn right and begin the journey back.  Sadly, one would have expected a canyon to be lined with old sycamores, oaks and such, but the fires wrecked havoc down here as well.  There are a spattering of survivors along this flat trail, but for the most part it's shade-less all the way back.

Campground and Ranch Loop (9.2 miles) - This course navigates around the northern section of the park including the campground area and the equestrian center both of which are temporarily closed pending re-opening of Bane Canyon Road (no re-open date has been specified).   This course is a continuous series of up and down hills some of which can be a bit strenuous.  Starting on Sapphire Road, head south on Bare hillsBane Canyon Road (under-construction ... sort of) for half a mile until you reach Bane Ridge Trail.  The trail is not marked but it will be the first trail on your right and just before the very large water tank.  This trail begins a gradual upward climb.  Your immediate reaction will be the complete absence of any noticeable vegetation other than grass.  The hills have been stripped bare of trees and shrubs (most likely the Sidewinderresult of the 2008 fire).   After 0.5 miles you'll reach Sidewinder Trail...turn right.  Many of the trail markers in this section of the park are in very poor condition, you may find, as with this marker that its is lying in the grass.  Sidewinder is aptly named (see photo).  It's a very narrow trail the hugs the side of hill; bikers will need to exercise caution!.  When the trail drops into a small canyon (0.6 miles) there will be another trail marker (you may have to look for it) for Upper Aliso Creek Trail...turn right, cross the creek and head back up the hill.  As you make your way along this narrow single-track, you'll likely get a feel Windmillof isolation.  As you look around, there are no buildings to be seen and in all likelihood not a person around with the possible exception of a lone biker or two.  Upper Aliso Creek continues for 1.2 miles; as it drops into another canyon (you'll see an old windmill on the right) turn right on Raptor Ridge Trail (the park map has this trail labeled Faultline but the marker says Raptor Ridge).  With any luck, you'll find this marker still standing.  Raptor Ridge Trail makes another climb up.  This trail is a narrow single track as well and continues for a mile until you reach a utility/fire road which according to the map is a continuation of Raptor Ridge Trail.  If you turn right you'll head in the direction of 4 Corners about a mile away.  For our purposes we'll turn left and head in the direction of the campground/ranch.  At this stage you'll be at an elevation of 1,350' Viewabout the highest point along this course (the starting elevation was around 820') though you'll not really notice since you've already made numerous climbs and descents.  In less than 0.4 mile turn right and continue down the hill and go for another 0.6 miles until you reach Telegraph Canyon Trail.  Turn left on Telegraph; in just shy of a mile you'll reach the campground area and then the equestrian area.  There is a nice picnic table here with a lovely view of the southern canyon.  As you sit and rest you'll have put in 6 miles at thisBane Ridge Trail point.  It's now time to head back.  You have a couple of options; take the under-construction Bane Canyon Road or Bane Canyon Ridge Trail.  We'll take the Bane Canyon Ridge Trail which is much more scenic.  It may be scenic...but it also the most strenuous.  The next 2.5 miles is a series of several hills which, with every climb, seem to get steeper.  But the views of the surrounding hills and canyons are worth it.

San Juan Hill and 4 Corners Loop (9.9 miles) - This course begins in at the  Equestrian Parking area located in southern section of the park.  This free parkingSouth Ridge Trail area is usually empty so you won't have any difficulty finding a place to park.  The trail begins by heading up a short paved road before entering the actual park and continuing along Quarterhorse Trail.  Between the paved road and the trail you'll make a steady, but short climb (0.5 miles) before reaching the top of the ridge.  At this point you'll turn right on South Ridge Trail which takes you directly towards San Juan Hill about 3 miles to the east. South Ridge Trail follows theSan Juan Hill ridge line but be prepared for a series of up and down hills along the way...none of which are particularly steep.  The trail is wide open fire-road and is very popular with bikers.  Just before reaching San Juan Hill there will be a narrow single-track which splits from South Ridge Trail and takes you to the top of the hill.  At the top of the hill is a small survey marker as well as a concrete block commemorating the actual battle of San Juan Hill back in 1896.  The hill offers nice 360 panoramic views of the park and surrounding communities.  In addition, as you look north, you'll see 4 Corners down below...the next objective of the course.  Continuing east, the trail to 4 Corners feels somewhat4 Corners convoluted as it heads east before meandering back west; from the top of San Juan Hill to 4 Corners the distance is just shy of 2 miles.  Four Corners is a junction of several major trails within the park, most notably, Telegraph Canyon Trail which is the major east-west trail.  Chino Hills State Park often feels empty and desolate but don't be surprised to find a bunch of folks taking advantage of the benches and shelter provided at 4 Corners; it's in the middle of the park and is ideal location to take a break.  After you've rested...it's time to head back via Telegraph Canyon Trail going west.  The section of Telegraph Canyon Trail between 4 Corners Telegrah Canyonand Sycamore Trail is the most scenic section of Telegraph Canyon Trail.  This is one of the rare stretches within Chino Hills State Park that offers any real shade as well as being one of the most scenic sections within the park; it's flat and peaceful, though very popular with bikers.  After 2.2 miles it's time to head back up to the South Ridge via Little Canyon Trail or if you prefer Easy Street which is about three-quarters of mile further along Telegraph Canyon.  The Easy Street route would be preferred if you want to maximize flat terrain.  Once on South Ridge Trail is back to the Equestrian Parking area in 1.6 miles.

Running
The trails in Chino Hill State Park are certainly worthy for those looking Runnerfor long trail runs.  The park has an excellent mix of flat trails (Telegraph Canyon Trail) and plenty of hills (for example either the North or South Ridge trails).  The trails are in great shape and make for easy running.  The major downside to running in the park is the complete absence of shade and lack of water.  Early morning runs are recommended and don't forget to bring plenty of water.   

Biking
This is really a mountain bikers park.  The trail network is ridiculously extensive and Bikersalmost all trails are open to bikers.  Bikers of every skill and fitness level will find something to like.  The relatively flat Telegraph Canyon Trail is ideal for beginners, while intermediate bikers will enjoy the climbs found along the ridge trails such as North Ridge Trail which offer nice elevation gains (1,000+ feet) but in a gradual fashion.  If climbing is your thing...be sure to try Bane Ridge Trail.

Hiking
There's a lot to like about hiking in Chino Hills State Park.  HikersThe 90+ miles of trails, scenic vistas, rolling grasslands, wildlife viewing and unique points of entry.  On the downside, there is very little shade, and for some, the constant stream of bikers might be a bit annoying.  Because of the Bane Road closure the northern end of the park is especially quiet; ideal for those looking for a sense of isolation.
