Full Day hike! Definitely separates the avid from the casual hikers, this is one hike you want to be acclimated for, or allow extra time to reach the peak. If there's a hint of bad weather, make sure you are prepared for it with at least a windbreaker and 10 essentials. You need to get a permit to enter the San Jacinto Wilderness. Get it from the station in Idyllwild. Day permits are also available at the Stone Creek Campground for this hike. There is a kiosk to the right just before you enter the campground registration area. If you can't get a permit for the hike, Marion Mountain Campground might be a way to sideline the 9 to 5 type restriction on permitting. If you get a campsite pass, you are supposed to be able to hike the Forest as well. You will still need a State pass for the area after about a mile and a half on the trail going up the mountain... Get both, or just stay at a campground and then get the State pass. There are several routes up San Jacinto. Most people take the Palm Springs Aerial Tram up from the desert floor and begin their journey in Long Valley. The lesser-travelled Marion Mountain trail skips the tram, beginning a few miles north of Idyllwild. It's the shortest route up Mt. San Jacinto. It's also steep, relentlessly climbing over 4,000 feet in under 6 miles.

Decently shaded. Stunning views. It is steep with bunches of roots and rocks, but it's not too crazy because it is well maintained. Well worth the time!

It looks as if they may be planning a trail change near the bottom soon, probably because water washes over the Marion trail at points. There's a water pipe that feeds a well which runs along the trail during the first mile or so, but it's not too obnoxious.

This was a stunning hike, I have hiked the peak from the Deer Springs Trailhead and done the loop before, and this hike shares some of that trail, but I had much more fun with this route. Its pretty steep for the first miles, but nothing too bad, the views are amazing towards Baldy and Gorgonio and the sunrise this morning made it spectacular. The air was clear and I found shade from the wind at the peak and spent almost two hours at the top exploring with my binoculars, could even identify peaks as far away as Las Vegas and the Grand Canyon. I met only a very few people on this sunday after thanksgiving and it felt like I had the trail to myself. Deff my favourite route to the San Jacinto Peak so far.
PS....And oh, you can get your permit at the at the Stone Creek Campground, there is a kiosk to the right just before you enter the registration area. No need to go to Idyllwild Ranger Station, time saver in the morning.

If you're looking for more of a challenge than the normal route from the tram, this is for YOU! The elevation gain is insane but its well worth it. There is a prickly and brushy area that sweeps your legs so wear long hiking pants.

hiked this with a a couple of friends last weekend and had a great time. perfect weather. trail ended up being closer to 13 miles than the 11.2 listed here. Marion Mt trail and the rest of hike up offers great views. trekking polls and plenty of water recommended. there a small Creek about half way up but nothing potable.

My boyfriend and I started hiking being of this year, February 2017. so we weren't the most experienced hikers. We started hiking this trail as a way to get physically ready to go to Yosemite national park. I have to say that this Trail had changed the way I see hiking forever. Our first attempts, we were only able to go a little more than a mile in. But we came back every weekend and now we are physically able to make it to the summit.
Info on the trail:
There are many switchbacks the whole trail, so you will get a decent workout. The trail will often give way to beautiful lookout points where many hikers will stop to take a break and take in the amazing scenery! This trail is well shaded and is especially cool in the summer months compared to the surrounding desert areas. It is a well known trail and if you hike it often enough you will get to see the same dedicated people each week. So a happy and fun community of hikers will be present here. be sure to bundle up and stay warm if you come anytime in the fall or winter. The best time to hike this area is from June to October but even now in September it gets rather cold in the mornings. of you can bring trekking poles with you, pls do. They can really help you during the elevation gain. All in all though, my boyfriend and I absolutely love this trail. It has made hiking a lifestyle for us. I will forever say this place is near to our hearts.

I completed this trail as my first peak of the SoCal Triple Crown in 24 hours. A friend and I started at about 1:30 AM and went slow and steady pace which took us 5h33m to complete. We measured the total distance from the parking lot to the summit and back to be 12.5 miles with EG to be 4,423'.

We had never been on this trail before so we drove to the trailhead at first but realized it was a campground so we drove back down and found the hiker's parking lot.

When hiking this trail it is possible to lose track and go down the wrong path at junctions. Have a good map and GPS handy to save yourself time and energy. Enjoy the view and the hike.

It was tough and technical with rocks and roots throughout. A very tough downhill!! The view at the top is spectacularly sweeping. And yes you can see Catalina, desert, mountains and basically most of SoCal. There are lots of side trails so keep your bearings and route with checks especially at the junctions.

Tough hike but very doable. Pace yourself and you'll do fine. Poles helped a lot on the steep sections. One thing regarding wilderness permits, you don't have to go into Idyllwild ranger station. There is a kiosk at the Stone Creek Campground near the Campground station where you can fill one out and drop into the box. Saved me a half hour coming from I-10.

Exhilarating.

Probably one of the most grueling hikes I have done yet bagging peaks! From the first step its all incline. There are some parts that level out after a couple of miles but then it gets grueling again with never ending switchbacks to the top then a rock scramble that you must climb in order to make it to the very top of the peak. Coming down is grueling as well since parts of it is very steep. Overall hella hard hike but rewarding and beautiful scenery to look at.

The parking lot to the first trail junction were brutal. Felt like we were going straight up. Be prepared to climb hard the first 1/3 of the trail. 5 hours up and 3 hours down.

Great tough hike! Not much to add as all the previous reviews are accurate. 13.5 miles hike starting at the parking lot, although the posted signs seems to be not very accurate with the distance, its longer than posted signs according to my gps. Most of the hike is in the shades. If you are mentally prepared, coming down wont seem as endless (thanks for one of the reviews). I consumed 2.5L of my 4L water. Enjoy this beautiful hike. Grab your permit, the ranger station is some 7-8 miles down the road on 243 highway. 6hrs going up and 4hrs coming down for us.

Did the hike today, July 16. Started around 7am and reached the peak around 10:30am. Was certainly a tough hike, both up and down, but well worth it. The views up top and along the way were fantastic. Lightly traveled and the temps started in the low 70s and topped out in the mid 80s. There are 2 ways to go and the Tram start would be much easier for sure. The hike took up pretty much the whole day and I need all of my 3L of water. I will certainly do it again, but it will be awhile.

This was a great hike. It's about 14 miles starting at the parking lot. Good solid footing unlike Baldy. The sticker plants were not fun but the view is beautiful so it makes up for it. The water falls were nice to see and the campground is a great place to relax for a while. The next part of the trail gets a little tougher since the landscape changes and it gets rocky. Once you hit the junction it flattens out to get you ready for the rock climbing adventure at the end. Most beautiful views as noted in other reviews. It was ok coming down until about the last 2 miles I was tired and that what was difficult going up is also difficult coming down. Overall it was a wonderful day and I'd do it again.

Solid hike with amazing views at the top.
The board below (at beginning of the trail) says the trail is 5.25miles long, but it actually turned out to be longer than that - it sucks to realize that you have to walk more when you are hoping that you reached the peak. But a very rewarding hike indeed.
