Brilliant hike, one of the top (and most challenging) hikes in LA, added bonus there is as act shop at the top (commissary) for Mount Wilson! You can make a loop back to Chantry Flats so you don't hike the same trail back.

This was an awesome experience, however my boyfriend and I did not realize how intense this hike was going to be. Good thing we had our head lamps because the last 1 hour was in the dark since it took much longer than we expected...8 hours! Definitely need to work up to this level but we were glad we did it even though it was the hardest hike we've ever done and we are in above average shape. Need to bring Gatorade, not just water but the overall experience was worth the pain...literally it was painful lol.

Fall 2003 -- A tip for hikers new to the trail: I have read accounts of hikers reaching the Toll Road and taking it all of the last mile or so up the west end of Mt. Wilson. The foot trail actually continues at Mt. Harvard entrance on the right of the road. It's easy to miss. I think it is nicer and easier going this way to the official summit directly at the Cosmic Café parking lot, especially if it's sunny.

Just fyi, many of the reviews below are mistakenly referring to hiking to Wilson from either of two principal routes from Chantry Flat, rather than along the Wilson trail from Sierra Madre. No Adventure Pass is needed for parking at the base of the Wilson Trail, nor will you find yourself parking far, far away as is often the case at Chantry. The Wilson trail is not shaded throughout -- in fact, the first 2.3 miles are quite exposed, and sunny unless you begin by shortly after dawn. There is not a series of steep switchbacks at the end of this trail; rather, it is fairly uniformly steep throughout, with an average gain of about 700 feet per mile. You do get a nice breather along a fairly flat section starting 2.7 miles in (junction of the unmarked "connector" trail, near the helispot) to 3.5 miles in (Orchard Camp).

Lots of ways up Mt Wilson. But also interesting destinations if you only have a few hours instead of a whole day. Favorite quick id Sierra Madre to Orchard Camp - reachable in under 2 hrs w. my pup. There is stream water at First Water (and Orchard Camp) so you don't have to lug so much water for the dog.

Also the route of the Mt Wilson foot race ion May - reachable in less tim e when you're running.

Great Hike! Be sure to arrive early with an adventure pass, we arrived at 7 am on a Saturday and there were only a few spots left. Hike is very strenuous. The switchbacks for the last 2.5 miles before Mt. Wilson are never-ending! Be sure to go to the lookout point on the top of the mountain. It is on the very East side, outside of the observatory.

Did Mt Wilson a couple of weeks ago. The weather was great. The entire hike with covered under a forest like canopy except sparse sections toward the top. I want to elaborate on the difficulty is that depends on your hiking skill but is definitely not a beginner hike due to the incline and mileage of the hike. A Although some will disagree with me a beginner could do it given enough time to complete trip.
