Mount Wilson via Chantry Flat Trail Directions:

Open in maps. Because you can drive to the top of Mount Wilson, be careful to not let the driving directions take you to the top. The trail head to Mount Wilson via Chantry Flat is located in Big Santa Anita Canyon with the same trail head for Sturtevent Falls. There is a small parking lot that fills up very early. If the parking lot is full, you’ll have to find street parking on the windy road somewhere. Don’t forget, an adventure pass is required. An America The Beautiful pass will also work.

Who Mount Wilson Trail Is For:
Novice Hikers: You might want to spend some time working up to this. I consider myself a moderate to advanced moderate hiker and this trail was tiring for me. If you’re new to hiking or working out in general, go with someone experienced, pack plenty of food and water, and go at your own pace. For those with any, medical problems or physical disabilities, please use discretion.

Advanced Hikers: This hike will be a fun challenge and the persistent switchbacks and elevation gain will be a nice leg burner.

Expert Hikers: This will also be a fun challenge and a great workout.

It’s always a good idea to be aware of what type of hiking level you’re at.


Best Time Of Year To Hike Mount Wilson Peak:
Keep an eye out for excessively hot summer days and avoid the trail on those days. Mount Wilson isn’t exceptionally high but sometimes winter storms can drop the snow level down below 4,000 feet. Unless you’re prepared for a snow hike, avoid it on those days. Dress warm on the colder winter months. Otherwise, your best bet is fall through early summer. Plan appropriately for weather conditions.
Mount Wilson Trail Conditions:

I’ve read from other sites that the trail via Chantry Flat can have some overgrowth, but that wasn’t my experience. The trail was made up of mostly dirt and very well maintained. The bottom of the trail runs through a Canyon with a stream that takes you up through several short man made waterfalls as well as Sturtevant Falls. Once at Sturtevant waterfall the trail goes through a very long elevation gain made up of mostly switchbacks until the observatory.

As the trail gets into the higher elevations the dirt trail gives way to some rocks on the trail but it’s not too bad. At the top where the observatory is located the walking path is paved until the trail heads back down. Most of the trial keeps you shaded from the sun by the pine trees in the higher elevations and by large oak trees in the lower elevation. Keep an eye out for poison oak. Rattlesnakes can be common in this area. Don’t bring any less than two liters of water and bring enough food to fuel you through thirteen miles. I had a sandwich, cliff bar, beef jerky, and an apple.
