Throop Peak, checking in at an impressive 9,138 feet, is one of the tallest summits  in the San Gabriels.   While it might not quite have the name recognition of nearby Baldy or Baden-Powell, it’s one that no So Cal hiker should miss.  The views from the summit, and on the way up, are spectacular.  While the hike is short, its difficulty shouldn’t be underestimated, especially for people who are sensitive to high altitude.  Its starting point of 7,900 feet is one of the highest in So Cal.

From the parking area, look for a big brown sign indicating the Dawson Saddle Trail.  Follow the highway west for a few yards and pick up the trail on the south side of the road.  You begin making some switchbacks, up past the sign and into the woods.

Soon you emerge on a ridge, where the views include Mt. Baden-Powell to the east and the high desert to the west.  There is a good amount of shade on the trail from the pines as you make your way up the north side of the mountain.

At 1.8 miles, you reach a junction with the Pacific Crest Trail.  Head right (southwest) and almost immediately, take another right on an obscure trail that heads toward the Throop summit.  This last stretch is quite steep and will probably have even veteran hikers stopping to catch their breath,but before long you arrive at the top.

The view from Throop includes downtown L.A., the Santa Ana Mountains, Mt. Baldy, Baden-Powell, the high desert, and more on clear days.   There are several logs and boulders on which you can take a well-earned rest and enjoy the views before heading back down.

By the way, in case you were wondering, this mountain is named for Amos G. Throop, founder of Throop University – now known as Cal Tech.



  1. Hi David – we did this hike in August 2016 (and added Hawkins) and it’s a nice one, though short. Last month we took this trail up to Dawson Saddle and then took a left turn, went over Mount Burnham and up to Mt Baden-Powell. That’s a pretty sweet hike if you haven’t tried it (though coming back up after Burnham is somewhat unpleasant). We also went over Burnham -instead of the PCT around it – from West to East, and took the PCT back. We also took a non-PCT train down from Baden-Powell – a ridge route. All of it was gorgeous. It’s a lovely trail. We figured about 8.5 miles, 745 meters 5 hours. PS – like your site’s search function on all devices!

    1. I have not tried Burnham yet, I should check it out. Glad to hear that the search function is working well. I mainly edit this site on a desktop computer and from time to time I look at it on my phone, but my perspective on how it loads/looks/functions on various devices is admittedly limited.
