Short but challenging hike. Great hills.

My boyfriend and I came here on a Tuesday morning and it was pretty solitary. We were the only ones hiking here. You will encounter a lot of horse and dog poop so watch out for that. We saw a rabbit, squirrels, deer and possibly a quail. There are two steep inclines that may kick your butt. As for parking, you can park along the residential streets.

As previously said...very hot... make sure you go earlier in the day. Not very good signage...was confused on where to start for the Little canyon trail bc the starting point doesn't have that listed as one of the trails. Make sure you take screen shots of map before you enter trails ...not way to access the All Trails map once you get in the canyon. Bring lots of water...very little shade. Lots of poop on the trail too : (

On a hot day like today, be aware there is very little shade. I think this hike would have been totally different on a cooler day.
Bring lots of water!!

Not my favorite trail mainly because your right along the freeway for most the way and mostly the only thing you see is the 91 and the traffic in the morning. The abandoned building toward the top is not actually part of the trail but that was cool to go look at too.

This trail is closed. Don’t know why this is not showing on the AllTrails app.

Pretty good hike that can take 1-2 hours to finish. Definitely want to go in spring when the hills are green. Everything is dead during the summer.

it was a nice sunset hike!

$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!

Great little hike! Lots of bikes on this trail!

Great hike! Nice views and a good workout. Lots of birds and small wildlife on the trail.

Everything’s been pretty dead this year since there hasn’t been much rain. It’s a nice easy walk but not much scenery

There was no activity that said dying or I would have put that. This hike killed me and my friend i went with. We went on a whim because my friend has been going through some stuff in life and has kind of given up on pushing themselves and seeing positive change. So we randomly did this hike today and let me tell you I thought we were going to die. it was amazing tho,nice scenery and the sense of accomplishment that came from it was incredible. We will be back for sure. It was the perfect challenge and the life metaphors drawn from the hike kept us entertained the whole time when we weren't telling each other we should turn back. Amazing hike tho 10/10 would reccomend.

This would have been a great hike if I had a not hiked alone, I did 9 miles, and went up to San Juan, that part was great. However, i went 2 hours and 15 minutes without seeing another human, very unsettling, and I hiked 3+ miles down in the valley and had something following me in the trees. I blue my air horn a few times and it stopped. There are active mountain lions here, don't hike alone, be smarter than me

The trail as shown on the map is closed (as of 5/20/18). You end up doing an out and back up the Telegraph trail. At about 4 miles in there’s a marker on the left for Gilman Peak. Get ready for a climb! Most of the elevation gain is in that last 0.5 miles. Once you get to the top, the views are nice! Definitely do this in the early morning before it gets hot because there is no shade.

lots of different trails. Beautiful views.

Just hiked this trai, with a 20 lb pack. l. FIRST - The directions are wrong. The easiest way to say it is go to the golf course and park, or park out on the road before golf course and walk the 1/2 mile. Then, walk behind parking lot ad see the trail down below, across railroad tracks, that's your trailhead.

It's 2 miles mostly winding UP to the intersection of Brush Canyon Trail (to the right) and Scully Ridge to the left...stay left. maybe a 2 1/2 mile stretch on the ridge, up and down rolling hills before the trail hooks around and heads into the canyon on, Lower Alisio. You stay on this, another 2.5'ish miles when if you're not careful, you will miss the right turn UP to Brush Canyon Trail, which is a few windy switchbacks, back UP to Scully Ridge and the trail back to the golf course.

If I didn't have the pack it's good for trail running, although the straight ups most likely to be hiked....

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!

Very nice today. Since last week, someone cleaned up animal waste on South Ridge, Telegraph Canyon, and even the large fresh horse dump on hiker-only Easy Street. There usually isn’t much waste anyway on these main trails, but I appreciate the maintenance (I see them occasionally grooming the bigger trails) or whoever did it.

Beautiful area, nice clean trails. Was looking to do less elevation so this was perfect for me. Most of the hike is a beautiful walk, except Easy Street which is the only part not easy. App did take me to Rimcrest Dr so it must have been updated.

on Telegraph Canyon Road

Went today, lower canyon portion was really green. Good views from the ridge, looking forward to coming back.

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.

Easy out and back along South Ridge Trail, or on the return take Diemer Trail north to Telegraph Canyon then East Street Trail back to Rim Crest Drive. South Ridge Trail west of Diemer Trail is not groomed often, if at all, so expect a healthy assortment of animal waste and red ants.

Fun but I would do for a while. The brush was over 6 feet tall and had to mash through cause was already committed and a lot of bees. Beautiful scenery though.

Nice 6 mile loop with a great view of the main sections of the park. Well maintained. Make sure to go left down the switch backs if you went up skully first to stay on this loop. Skully ridge continues on if you go right.

$5 to park which was good only because we got a map. The northern part of this trail is closed so we had to take a more southern route which was still like 9 miles but not as much elevation.

Nice and challenging trail. Took me about 2 hours. Not much shade. Saw lots of bunnies and lizards. Birds were singing. Shortly after the pay area, there's a bathroom. Maybe a water fountain. I'd revisit after it rains. So much brown and not enough green.

Fantastico!
