Loved this trail. I did this as a sunset/night hike. Took a head lamp for the night part. I will definitely do this one again. Even though you can do this at night, take plenty of water, electrolytes and snacks!

Decent incline all the way up! Wildflowers paved the path most of the way too :)

Great hike! Kind of challenging both up and down in different ways... I would definitely get there at 6am to beat the crowds. Literally nobody going up but a million people coming down lol... plus we were shaded the whole way up and most of the way down! Loved it!

I hiked to the top for watching fireworks at Rose Bowl on July 4th. Great views at the top. I felt safe hiking down with lots of people at night. Plenty of street parking.

Great views...fairly challenging. Go when it's cool, as the trail provides almost no shade.

Started the hike before 6 am and was nice, cool and lonely. Coming back down was a different story. Too crowded for my liking. Was a nice incline, got my heart pumping. Bugs at the top were out of control. Vegetation is very over grown. Overall nice but will probably never return.

This is a great hike, plenty of views, sunshine. It is a busy trail. Kid-friendly (maybe). Make sure that you have plenty of water as there is no water on the trail and back. There is a water fountain near the entrance. The summit is great. You can proceed to Mount Lowe once you get to the top.

I really enjoyed this hike. The trail follows many switchbacks to the top. There’s some interesting history one you get to the peak and lovely views. Wear a hat & bring sunscreen as the trail is largely exposed.

hey was up fellow future hiker. this is a great hike but please be prepared with water,iced fruit,sun screen, good all terrain shoes,sun glasses,hiking stick(its a steep mountain). The view to the top is worth the hike as you've seen from the pictures. parking can get limited 8am and forth.

A nice, moderate hike with not a ton of shade but beautiful views.

great! a lot of people tho, so it is a little bit noisy once you get to where the echo house was. other than that it is an awesome hike!

Pretty cool hike. I went on a very overcast day so I wasn’t able to see anything but at the top they have some cool remnants of the Echo house and the rail. Very steady gradual incline on the way up but an awesome workout.

Easily the most beautiful trail in LA.

A very fun, moderate hike with a nice area to explore at the top with historical landmarks, picnic benches, trees. I encountered many trail runners (50?) and even at 6:30 am on a Saturday already pretty crowded. The earlier the better, or twilight might be nice though it’ll be buggy right now. Make sure you go straight and don’t take the first trail to the left, but continue to the path just beside the cacti that leads up the mountain.

Trailhead easy to find and nice plants and flowers along the path! End of the trail is cool because you get to see some historical sites!

I love this trail! Great steady incline. Beautiful views.

At least 2 miles longer than what is stated. A lot of incline. Some shade. Picnic area at the top and great views

Sam Merrill trail to Echo Mt was a nice short hike. 3 hours max, add time for picnic at the ruins and meditating at view points. Saw blue Jay's, squirrels, a garter snake, gazillions of lizards, swallow tail butterflies, bees, several types of wildflowers and angelic cloud formations. It was a hot day. Saw one mountain biker and several trail runners. Trail is well kept. If you are a regular hiker, poles not needed. Not a lot of shade, so a hat and sunscreen are recommended. Probably okay for kids over 5. Saw some peeps with their dogs, they looked like locals.

Lots of traffic and a little tough to run in many places. Beautiful views and pieces of amazing history.

Love this trail. Not too difficult, but gets your heart pumping a bit if you walk it fast. Beautiful views. Interesting destination. Looking for similar trails in the LA area.

Took the Firebreak trail. Features some light rock climbing, exceptional view of the city, surrounding mountains, and the ocean. The entrance to the trail is to the left of the Cobb estate gate, once u see a painted bench you are on the right track. Have fun!!!! Be safe!!!
