$5 cash to park (you need exact amount)

I saw a rattlesnake, lizards, squirrels, and birds!

Very clean trails.

Not much shade on the trails so bring hat and sunscreen.

Telegraph is mostly flat ground or a very slight incline.

There is a portable bathroom at the end of telegraph trail! Also there are bathrooms next to parking lot.

This 9.4 mile hike kicked my butt!

Hiked today. Missed the left turn when we went off path to top of San Juan. Added 2 extra miles (oops) If you go counter clockwise, add an extra 2 miles, and carry a 50lb pack, that last hill is a butt kicker!

I really enjoyed this route yesterday morning. First time I tried it clockwise. It’s easier going clockwise because the bulk of elevation gain is stretched out over 4 miles on Telegraph Canyon and Bovinian Delight and you almost don’t notice it.

Mostly fire roads but the cut through to Telegraph is an single track. Single track is mostly downhill (fast) if traveling north. Lots of gain at the beginning and end but enough downhill in the middle to recover for the hills at the end. Enjoy....

Yellow mustard flowers were awesome although overgrown. The mustard blocked some of the single track in the canyon. The fire road was nice. Great downhill fun and the uphill climbs were not bad.

This trail was tough, the first 2 miles is all uphills. I spent the first 45 minutes walking my bike to the summit. Due to time constraints, I back tracked at this point.

More to follow later.

This was a very nice and peaceful trail. There's many options available. We took the trail in the middle. (Didn't get the name) this hike was very peaceful.

Nice trail, very well kept. It was an overcast day so it was a good day for this hike, trail has no trees. We did the full loop and about mile 6 approx. we found a shaded area with a picnic table, perfect are for lunch :)
This trail is rated moderated, but in my opinion it should be rated "easy". I would say it's a good beginners trail.
It is just long (10 miles).

Pros: pretty good Hike for distance and elevation. Wide well kept dirt trail with some rocks.
Cons: Absolutely no trees.
The best time to do this trail is early morning with overcast. it's was 85 with 15 to 20 mph winds the day we did it. One entrance for cars is about 2.5 miles to trailhead and parking lot. The day we hiked the gate was locked for red flag fire warning. We walked in to the trailhead on paved road adding about 5 miles to the hike. Property will be back but must check before to make sure can drive to trailhead and choose a overcast cooler day.

A very nice, well marked and maintained loop trail with something for most everyone. Depending on the options taken, the trail can be as short as 7 miles to as long as 14.25 miles. This trail is located in Chino Hills State Park. The trailhead is located off of the parking lot for the Park's Discovery Center. After about .3 miles on the trail there is a "Y" split where the trail branches off to the North Ridge Trail to the right and continues as the Telegraph Canyon Trail to the right. According to California State Park Service, the North Ridge Trail is closed until April, 2015; so, continue on the Telegraph Canyon Trail. After about another 1.65 miles there will be a trail marker for the Diemer Trail to the right. Take the Diemer Trail. It is a short trail, all uphill with barely a switch back, that connects with the South Ridge Trail. Once on the South Ridge Trail, head left along the trail. As the name implies, the South Ridge Trail runs along the ridge of several hills. So, expect a lot of sun exposure and rolling hills. This segment of the loop is not really for those looking to commune with nature. It is basically a service road for the utility easements running through this Park, and at times it literally borders the back yards of some homes in the City of Yorba Linda. However, the South Ridge Trail does offer some nice views of the cities in Orange County and would be a wonderful place to see wild flowers during in early Spring. Along the South Ridge Trail there are trailheads for a number of smaller trails. Each of these smaller trails will lead back to the Telegraph Canyon Trail. By taking any of these smaller trails to the Telegraph Canyon Trail and then continuing on the Telegraph Canyon Trail back to the Discovery Center, one will complete the loop. The first of these smaller trails is the East Street Trail, which make the loop a 7 mile hike. Then there is the Little Canyon Trail, which will make the loop a 8.3 mile hike. Finally, there is the Bovinian Delight Trail, which will make the loop a 12.9 mile hike. If one does not take any of these smaller trails, the South Ridge Trail will eventually reconnect with the Telegraph Canyon Trail. This will make the loop a 14.25 mile hike. For a short side trip, on the South Ridge Trail, past the trail marker for the Bovinian Delight Trail, there is a spur trail leading up to San Juan Hill, this is the highest point in the Park. Once back on the Telegraph Canyon Trail, the scenery changes dramatically from the South Ridge Trail. Because the trail runs down the middle of a canyon, along the Aliso Creek, there is a lot of vegetation and shade. This makes for a nice walk/hike back to the Discovery Center; the grade is all down hill. Since the Telegraph Canyon Trail is also a service road for the utility easements running through the Park, it is much like walking down a small country road in rural America. The fact that the Telegraph Canyon Trail is a service road really is not a negative. Some may say it actually adds to the appeal of the trail. For those interested in getting started in mountain biking, the Telegraph Canyon Trail is a nice place to start with this sport. Since the Telegraph Canyon Trail is a road and the elevation gain gentle (approximately 100 feet per mile), this is a pretty unintimidating trail to initiate into the sport. For hikers and equestrians, sharing the Telegraph Canyon Trail with mountain bikers really does not detract from the experience. Since Telegraph Canyon Trail is not a single track trail and is only moderately used, there is plenty of room to share, and for the most part everyone is considerate.

The 4.5 mile South Ridge-Telegraph Canyon Loop in Chino Hills State Parks provides a great trail for an after-work sunset hike in Orange County. (Date hiked: May 11, 2011 and March 28, 2009.)

Good ride for beginners who want to test their legs with steep interval climbs, at least on S mountain part. Bovine trail to telegraph is basic single track and telegraph is a trail my grandmother could ride.

Better than nothing

During the day this trail is pretty quiet. Get's a little busy after work hours. Usually take the middle trail (Old man's or Dead man's or something Man's trail); all overgrown with brush at this point of the year. Lots of wildlife (rabbits, squirrels, snakes, lizards, various bugs). Lots of buffalo gourds and castor plants. If you go that direction, towards Telegraph, the hill is very steep. Very few passers by. Great views of Yorba Linda and the 91. This is an easy hike. Only one small creek to hop over.

Slice of nature in the middle of the 'burbs.
