Mt Wilson, at 5,712 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.

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. Some times it opens early. It’s not uncommon to have people waiting for the gate to open.

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.

When the lot is full, people park down on the side of the road and walk up to the trailhead.

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.
bathrooms at Chantry Flat
There are basic bathrooms at Chantry Flat.
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.

It also helps to have insect repellant in case the flies are out. They can get annoying.

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.

If you want to check if there’s snow on your hike, read this guide.

La Sportiva Spire

I try a lot of hiking boots and shoes, and there are some great options out there, but the La Sportiva Spire is the best combination of comfort, protection, low-weight, and durability. They are waterproof, and the high cuff keeps debris out without the need for a gaiter. Time tested over thousands of miles. Use them with a two-layer sock system to end blisters for good.
Reviews & Lowest Prices: WomenMen

Osprey Talon

On a medium or longer hike I recommend a pack like the Osprey Talon 33 (men) or Osprey Sirrus 36 (women) which is a little bit larger. These packs are on the upper end of the (35L) daypack range, but they only weigh a small fraction more than a pack with less capacity. Having the extra space gives you more flexibility and means you don’t have to jam things in there. I use the space for things like extra layers in the winter, extra water on desert hikes, and even a tent & sleeping bag on overnights.

Garmin Inreach Mini Beacon

If you’re not familiar with the Garmin InReach technology, it allows you to send and receive text messages where you don’t have cell phone signals. You can also get weather reports and trigger an SOS to emergency responders. Even if you don’t have an emergency, sending a quick message telling a loved one that you’re okay or are running late is well worth the cost. The Mini fits in your palm and weighs next to nothing. Read my review and see the lowest prices and reviews at REI.

Fenix 6 Pro

I’m a big fan of GPS watches to follow my GPX track (which I also use as a sleep, wellness, and fitness tracker) and my current watch is the Fenix 6 Pro Solar (full review here). I load my GPX tracks onto the watch to make sure I’m in the right place, and if not, the onboard topo maps allow me to navigate on the fly. It’s pricey but it has a great battery, accurate GPS, and tons of functionality. If you want something similar without the maps and big price tag, check out the Garmin Instinct which is a great buy and does a lot of the same things.
