this was a really nice hike but it's a fire Road most of the way but the views from Inspiration Point are something special and it was 8 miles round-trip and we saw a bobcat

If you want a adventures hike take the Castle Canyon trail up to inspiration point. It was challenging but a shaded trail with great views. We took the Sam Merrill trail down. It was a nice trail covered by trees at first but then it was switchbacks and full sun exposure until the end of the trail.

As soon as you hit the trail you’re climbing switchbacks all the way up until you hit Echo Mountain point. Beautiful views as your climbing and at the top of Echo Mountain. We went up to Inspiration Point thru Castle canyon trail, it’s a challenging trail with plenty of shade and great views. We came down the Sam Merrill Trail from inspiration point, at first it was nice, lovely tress and shade but then it was switchbacks all the way down with full sun exposure and no shade. As challenging as castle canyon trail is I Would definitely do this hike again.

Seen a bear less than 1/4 mile from inspiration point telescopes.. it was less than a foot from me and another hiker eating some left over trash someone should have carried out with them.. non the less the bear was small and easy to scare off... cool hike liked the feeling of being above the clouds once to the top.

Good hike. But the first part (Sam Merrill Trail) to get to inspiration Pt is very highly trafficked. Inspiration Pt trail is super steep but a good workout. It was overcast so couldn’t really see much. Lots of rocks going up and down. Overall good one.

Loved it. Worth the hike to the top.

Did this trail earlier today and it was invigorating to say the least!!! I didn’t know I had a fear of heights until hiking this trail because the path really gets narrow and steep with loose rocks so you really need to watch your step. The views were amazing and the weather was beautiful. I was prepared and had lunch up top at the picnic area where the big house used to be. That view is a must see. Great for those that have some experience and aren’t afraid of heights. Will definitely be back to hike the other trails!

UNA EXCELENTE AVENTURA UNA MANERA DE ECONTRARCE CON LA NATURALEZA ...

Took this trail downward coming from Chantry. Did a solid 24 mile hike. Reviewing this section because I wanted to give a shout out to the chap we bummed water from because we were at dangerous levels of dehydration. Lesson one, this whole area is very dry and has no water to speak of. Exiting from this location coming from Red Box, make sure you have tons of water during the summer.

This is a great trail with some shaded creekside walking for the Arroyo Seco part. The Ken Burton Trail is a well maintained up (or down, depending on your direction) and the Brown Mountain Road is a gentle slope with some good views.

Nice winding narrow cliff trail with great views. Not for those afraid of heights or children. Up top you will find the old mountain house ruins and history plaques making it my favorite hike thus far.

I love inspiration point I will return a million times more, I feel a divine inner peace

Great workout. Nice view in lieu of copious smog. The 'Echo Phone' is a blast!

Excellent hike. We exactly followed the route in the app, and my new Garmin GPS has the distance at 11.6 miles, which is longer than the advertised 9.8. The vertical gain is spot on. Need to be wary of mountain bikes going fast downhill, particularly on the single track portions. Suggest you plan a forecasted clear day to really enjoy the view from Inspiration Point.

This trail is much more challenging than advertised. The majority of the trail is exposed and covered in dry brush that you have to contend with. It’s pretty heavily rutted out from mountain bikers and heavily trafficked. A couple of nice views but nothing amazing. It’s long with some intense climbs. Bring plenty of water and the right footwear. There aren’t many places to stop and rest. I didn’t enjoy it. According to my AllTrails data it was 15.5 miles. Would not do this again.

My favorite hiking trail, the sunrise and sunset is amazing and it’s quick and easy.

Amazing workout and views!

This trail is great if you are looking for a solid 5 mile hike. It is a great hike if you are looking for a workout. You gain a decent amount of elevation (1400 ft) so you get high enough for a view of the San Gabriel Valley. The air conditions were pretty terrible with the smog from Los Angeles and the smoke from the several forest fires throughout SoCal. It is a very crowded trail so I prefer doing it at night and being able to see all of the city lights. I did see a rattle snake right on the trail so I would be aware and not play your music too loud so you can hear it.

I usually go to this hike but not during summer and it’s great. The only complaint I have is that some people aren’t considerate of the trail. Whether it is picking up after themselves or not making space for other people to get through I took off a star. The reason I say this is because it is a narrow trail and some can go down in pairs next to each other and the person going up doesn’t have space. All I’m saying is be mindful to stop and let that person go or not stand next to each other going up or down.

Otherwise great hike.

Nice and very hard . Yes

great hike we want to go back soon

The elevation gain posted here is correct but not the mileage...it is at least 1 mile longer than the posted 9 miles if you do the loop...definitely recommend getting there early to avoid the heat and the crowds that come later...I usually try to start around 6 am. Hiking poles aren’t needed but could be useful for some people. Depending on the weather conditions when you do this hike, I think 2-3 liters of water should be fine.
From the Cobb Estate gate it is about 2.5 miles up to Echo Mtn. From there you can either start with the San Merrill trail or the Castle Canyon to get to Inspiration Point and use whichever one you didn’t take up to get back down to Echo. My GPS measured Castle Canyon to be about 1 mile shorter.
Distance- 10.1 miles
Duration- 4-6 hrs
Difficulty- hard

*easy to find street parking and no Adventure Pass needed

Great hike last nite and way to step into my birthday..As I keep doing this hike weekly, I definitely feel a positive difference in my body and mind and its conditioning me to level up with ease onto longer and higher altitude trails.

Yes it’s been so hot this summer!! BUT this trail is nice and shady if you start as early as 6am. You would definitely need all terrain/hiking shoes. WATER and snack as well. Too many mountain bikers so Earphones headphones is not a good idea. Due to recent fires the view wasn’t as good but will definitely comeback!! Really liked the trail and if you’ve never hiked be ready for a great uphill downhill leg workout! :))

Great hike. I was tempted to take a star off for the amount of fellow hikers. My friend and I were slow, so we were constantly moving to the side to let others pass (our problem, not theirs). However, the hike itself is worth five stars. The "destination" at the end was fun and the views were great. We started at about 6:45 am and were in shade most of the time, which was wonderful in the SoCal summer.

This is a definite "share the road" experience. Equal numbers of hikers and mountain bikers. Most bikers were considerate (had bells and let us know how many were still coming) and friendly. However, there were one or two that flew around the corner and nearly mowed us down. One guy said "My bad" as he flew past us--if he had a bell, we would have heard him coming--get a bell, dude! My friend and I started at about 6:45 on a Saturday morning. We actually went counterclockwise, not on purpose, and only did about the first 4 miles, then turned around. It was a great hike and we will do it again, for sure. (Next time going clockwise, so we can actually see the stream.) There are a couple of places where the trail narrows or has a recent scree pile to navigate over, but all-in-all, a lovely hike. About 50% has cover and is cool. The steam on the side we went was a trickle and dry in many places--but it's august, so..

really good hike.
I actually did 12.4 mile total.
I started from Sam Trailway worked my way up to Inspiration
( I took the longer way) I liked the challenge. Came back down the same way I went up. You definitely need at least 3 or 4 liters of water in a hot day. Took a sandwich and orange and u survived lol.

Yes this hike is recommended for advanced hikers.

We met up slightly after the sunrise for a relatively cool hike, despite the season. The mountain ridges on the way up shielded us from the sun for the most of the ascent, and a bit cloud cover was an extra gift as well. The views on the way up are unparalleled, both of the San Gabriel Valley, JPL, and the San Gabriel Mountains. Once at the top, there sits the ruins of an old resort, the Echo Mountain House. There is a super cool Echo Phone towards the end of the ruins, past the water basin, which has some bright color graffiti. There’s a lot to see up here, not to mention the panoramic views of the Los Angeles area. The whole hike took about 3 hours for us, with a break at the top. I highly recommend this one. It’s a medium difficulty trail, because of the ascent, but probably a good transition for beginner to intermediate hikers. I’m definitely coming back, but I want to try some of the longer routes, possibly from the Sunset Ridge Loop Trail.

Hope you enjoy!
