For National Trails Day 2019, I decided to do a last-minute sunset hike in Angeles National Forest to San Gabriel Peak which I think is one of the best hikes in the San Gabriel Mountains for all hiker levels.

On overcast days, it’s always a debate whether to attempt a sunset hike or not because I feel like there’s usually no views… but I always regret it – so I went for it. If you’re ever unsure – don’t question it and just go because if you’re lucky, you’ll be rewarded with the most epic sunset colors in the sky.

San Gabriel Peak Trail

The hike to San Gabriel Peak is a short, out-and-back trail starting at the Eaton Saddle trailhead on Mount Wilson Red Box Road off the Angeles Crest 2 Hwy. There are parking pullouts on both sides of the road and it’s the same trailhead that you take for Mt. Lowe, Mt. Disappointment, Mt. Markham, and many other nearby peaks in the San Gabriel Mountains.

The trail starts on Mt Lowe Road which is a flat fire road that connects to the old Mt Lowe Railway. It runs along the side of the mountain for 0.5 mile and you’ll walk through the Mueller Tunnel after the first 5 minutes before coming to a junction with a large water tank to your right.

At this junction, you can either go straight to continue towards Inspiration Point & Muir Peak (which you can also access from Cobb Estate/ Echo Mountain in Altadena), head up the trail to the left which leads to Mt. Lowe, or hang right to continue on the San Gabriel Peak Trail towards San Gabriel Peak – this is the trail you want.

The San Gabriel Peak Trail section is only 1.1 miles one-way and has some elevation gain; most of the incline is on the latter half of this trail. The views will open up here as you get a little higher and at 0.7 miles when the trail reaches another junction, you’ll want to continue to your right (the left goes to Mt. Disappointment).

From here, you’re only 0.4 miles away from the summit. This part had slightly steeper sections so be extra careful on your way down. At a comfortable 45 minutes from the start of the trail, we reached San Gabriel Peak and instantly got rewarded with an inversion and the sun glowing warmly above the clouds!

We stayed for an hour to enjoy the whole sunset which I rarely do any more on local trails and brought our headlamps to head back down in the dark.

Hiking above the clouds:

An INVERSION is basically the reversal of the normal temperature behavior, so the cool air sits closer to the surface and the warm air hovers above it.

I didn’t look into the scientific reasons behind this occurrence but from my hiking experiences, I’ve learned that when I start a hike on a cold/ gloomy/ cloudy day and I am either hiking through the clouds (usually pretty cold) or I drive up above the clouds or through it, that’s when I am more likely to be rewarded with the “above the clouds” views.

Sometimes the trail will start warm, get cold as you’re going through the clouds, and warm up again once you’ve gotten above it, but just because it’s a cloudy day…. doesn’t mean you’re guaranteed these conditions.

It is possible to have it at low conditions though as I’ve seen at Henninger Flat and in the Santa Monica Mountains. I’ve also been lucky enough to camp overnight and wake up above the clouds, but if you’re looking to catch these conditions, you don’t always need to go to high-elevation trails. Sometimes it’s in the mornings, sometimes in the evenings… don’t try to narrow down the time frame and just go for it 🙂

    1. Really enjoyed your description. I did the climb many times in the past and was always leery after reaching the summit of that almost sheer drop that falls many hundreds of feet below to the fire road. I always felt more comfy packing a revolver in my kit bag. Great view. I can savor a cup of tea and enjoy the view of SGP from my dining room window here in Huntington Beach on a clear day. (Jim)

      1. Wow Jim, didn’t know you can see San Gabriel Peak from the coast! Also, not sure what section that sheer drop by the summit is…
