HIked today with 100 F temp. Had to take many stops along the way under the small trees/cliff side. The view is always great especially when no one else is there besides yourself.

With 1300 feet elevation gain in about 2.7 miles, this hike is a legit workout. The view at the top is one of the best of LA, but next time I'll go on a weekday (Sunday was busy).

Go all the way to Inspiration Point! It's worth it!

Start at Cobb Estate, take the Sam Merrill Trail to Echo Mountain - 2.5 miles of switchbacks with a steady incline. I started at 8:30a and there were quite a few people there heading up. The trail is nicely maintained, with prominent trail markers along the way. Once you hit Echo Mountain you can rest and take in some of the history from the hotel that burned in early 1900's, and remnants of the Mt Lowe Railway. Once you've regained your momentum, you can go two ways to get to Inspiration Point: go to the far right trail for Castle Canyon (adds an additional 2.2 miles one way to your trip) or the Mt Lowe Railway Trail (additional 3.6 miles one way). There were a few areas of the trail that had trash (those that had to "go" left their used tissue on the trail) so please pack what you take. Overall, took me 6 hours, total of 12.2 miles. Not super hard, but not easy either, definitely a leg burner. Watch for mountain bikers on the narrow trail - most have bells so you can hear them coming.

Start in the city...and end up in the pines! You can take the extension of this trail all the way to Inspiration Point (RT: ~10 mi, EG: ~2,800 ft.) for some truly inspiring views! Great hill trainer with a few technical spots & some steep drops-but the views are simply rewarding! You'll even run into a few pine trees & maybe some singing Blue Jays:D Just be sure you *start* adequately hydrated & of course "run with water" as this is a mostly southern face, exposed trail.

Brutal in summer heat. One nalgene won't do it. Cool payoff at the top, but otherwise not an exciting hike via this route. Would recommend coming in from the North.

Non stop uphill. Totally worth it

Great work out. Pretty view and picnic area at the top of the mountain. Bring water- not too much shade.
