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. The Chantry Flat parking area opens at 6am and fills up quickly. You might have to drive down the road to park if the lot is full. There are basic bathrooms at Chantry Flat. 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:

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. Mt Wilson From Chantry Flat Trail Maps

This is a little tricky. Avoid the trail by the USGS marker, and instead take the trail by the Mt Wilson Trail sign in the middle of the lot.
