Fascinating historic railway, great views, pine trees, deep canyons. This is a hike along the ruins of the Mt Lowe railway, Echo Mountain, and the Alpine Tavern. These locations were the most popular in Southern California in the late 1800's, before being destroyed by floods and fire. More than a dozen historical markers along the way tell the fascinating story of this railway. To top it off, the hike includes stunning views, pine forests, deep canyons, and lots of hiking. The first half of the hike, up to Alpine Tavern (now Mt Lowe Camp) and Inspiration Point, follows the Sunset Ridge Fire road to the top. The return leg is a bit more convoluted, but quite fun. A quarter mile down hill from Inspiration point, take the Sam Merrill Trail to Echo Mountain and visit the ruins of the former Inn at this location. Next head right on Echo Mountain Trail back to the Sunset Ridge Fire road. A hundred yards down the fire road on the right, take the unmarked trailhead for Sunset Ridge Trail, which parallels the fire road, and will get you home.

Love this trek. It’s a good one. The wildflowers are gorgeous this time of year. Lots of people who aren’t being mindful with face masks, so make sure you bring yours !

Really fun trail with some fantastic views (even if it’s smoggy). Parking lot is small but there is a lot down below that you can park at. MUST HAVE A PARKING PASS FOR LOWER LOT. Another work around if it’s too crowded is to start by hiking up echo mountain and doing the loop then coming back down echo mountain. The bathroom at mount lowe campground is in great shape as of 02-02-2020

Great hike with fantastic view and cool spots to see. Added a loop up to mount Lowe which was spectacular. Challenging but very doable.

The trail was nice and goes alongside the road for a while. There were great views of the city from inspiration point, and the trail itself was not hard. I'm not sure about the distance, because a different app we used recorded 12 miles, and the entire loop took 6 hours, including a 30 minute lunch break at the top. Weather was pleasant at the bottom, but chilly at the top, so i'm glad I had a puffy jacket with me. There is a single, very small stream to fill up water (if you have a filter), and it's about mid way point of the loop. The downside is that there are many mountain bikers that go very fast downhill, so you're always a little bit on edge. That would be the main reason I wouldn't do this trail again.

Did this in about 5hrs with leisurely stops. Great hike. Challenging but not too hard. Avoid the scramble trail (there is an option to take it, you can stick to the fire road) if you’re not in the mood for a challenge!

It was a great hike. I did the hike clockwise direction. There's opportunity to visit Echo Mountain and Inspiration Point. There's some bugs but not too much. Lots of shades and the temperature was cool throughout the hike. I will definitely do this again.

Good for how close it is to the city. Otherwise it’s okay- follows paved road for a significant portion which is disappointing.

This is a great trek. Inspiration point is gorgeous and taking the Merrill trail back down proved both fun and gorgeous. Make sure you've got plenty of water, the fire road can be gnarly if you're doing it mid-day.

I can't believe there are hikes like this within 45 minutes of West LA! A nice variety of surfaces, flora, little bit of fauna. Very solid. I did the loop(s) clockwise which meant a longer uphill and a steeper downhill which I probably shoulda reversed since I like running my descent. Anyhow, if you've done the six pack of peaks and are looking for something new, totally give this a try.

Очень понравилась тропа. Начал в 8 утра, спустился в 12:30 с одним перерывом. Есть и участки с теньком и солнечные. Прекрасные виды. Часть спуска сильно похожа на внедорожье, но так даже веселее

Great trail with high elevation gain’s. Flora changes from the base of the mountain all the way to the Summit. Allowing you to see shrubs and hardwood trees on the same hike. Fauna includes deer, raptors, coyotes, bobcats, and the occasional bear if you get lucky. Bring at least 40 oz of water if you plan on doing the full hike from the base to the summit, I would bring more if you like to stay hydrated. The summit offers 360 views, allowing you to see Los Angeles, Mnt Baldy, and the Los Angeles National Forest. It’s a great hike year round, but especially fun during the winter months when the summit gets covered in snow.

I highly recommend you start by doing the face up Echo Mountain which leaves you on the fire road not to far from the Mt. Lowe trail. The high intensity begin makes the rest of the hike easy breezy.
