Mt Wilson, at 5,710 feet, is the peak with all the radio towers that sits behind the LA skyline. It’s not the tallest peak in LA, but it’s a great hike with a fun summit. Multiple hiking trails ascend Mt Wilson. This hike starts at Chantry Flat, which gives you a gentler climb to the Mt Wilson summit, a trailhead store, bathrooms, and great views of LA on the way down. It’s a fun hike and a good long hike for beginners.

And if you’re a history or military buff, Mt Wilson is named after General Patton’s grandfather.

Getting to the Chantry Flat Trailhead

Use this GPS address: Chantry Flat Recreation Area, Sierra Madre, CA, 91011, USA.

The Chantry Flat parking lot fills up early. Get here as close to opening at 6am as possible to ensure that you have a spot. You also need a parking pass for the lot.  I use the affordable National Parks Pass, which gets me in every national park, national monument, and national forest. You can also use an (Southern California only) Adventure Pass, or buy a $5 day permit from the general store in Chantry Flats.

Mt Wilson Trailhead
Here’s detail of the lot and where the trailhead is.

If you want to take public transportation, there are sometimes weekend shuttles from the Arcadia Gold Line station. Check out the website or give them a call to see if it’s running when you want to go.

Gear for the Hike

Even though Mt Wilson is a beginner friendly hike, its long and you should have hiking gear, not just workout clothes. It’s rare for Mt Wilson to get snow, but it does sometimes. And in the summer, there can be thunder storms. Check the summit forecast before you go.

Here’s what I bring:

If you want hiking gear recommendations, check out my full gear list. I only recommend and review gear that I actually use. No company pays me to push their product. Everything on my gear list is battle tested on the trails, and should work well for you too.

See The Gear I Use

The summit is home to Mt Wilson Observatory, where you can take a guided tour of the telescopes and grab a snack at the Cosmic Cafe. Generally when I do the hike, I skip any observatory visits but always grab a snack at the Cosmic Cafe. The views are great. And you’ll have a sense of pride having walked up Mt Wilson as you brush elbows with tourists who took their cars.
