Beautiful Views! Best in LA!

This was my first time to Angeles Forest and enjoyed this hike very much. From trail head to Little Jimmy was only about 2.3 miles. Check out the Little Jimmy Spring, water was great and does not need to be purified. Campground was not crowded and the views are great! Only part of the trip that sucked was everyone who parked at the trail head had their cars broken into, mine included. There aren't any police or park rangers in the area and this seems to make the parked cars easy targets.

Good for moderate hikers, wear hiking boots

Moderate incline, beautiful views. Trail can get a little narrow but never scary. Will definitely camp next time. Campsite looked very spacious and comfortable - lots of bear-safe food containers, fire pits, picnic tables, toilets etc. Also close to the fresh water spring.

I've done this trip a few times and so far it's one of my favorite. The spring is flowing, large campsite with plenty of trees for hammocks.

When here on two backpacking trips so far. It's only a 2 and a half mike hike to camp (wish it was longer). Went one year in the summer and one year in the winter where there was snow everywhere. The snow trek was dangerous if you don't have crampons. I will go here often!

We did this trail with my son's Boy Scout troop last October (2016) as a one night beginner backpacking overnight for the new scouts. It was great! Good variety of ascent, descent, narrows, and just enough strain to make it some work, but not too much for the new guys. We got the camp site we wanted up at the top away from the rest. Great hikes and views in the area, good water source down the trail from the camp site. I'd say the only negative was the bathrooms, but it is camping after all, and the camp fire ban - but that's no one's fault.

For local hiking and camping this place is great. Picnic tables, firepit, stoves and vault toured
toilets, plus ample spaces for camping. Not much hiking distance to hit the campsite. Love this place.

Beautiful quiet tranquil The snow and cool gentle breeze through the pine trees makes it mesmerizing and fragrant.

Loved it! Went up 3/18/17 on a sunny day with a group of 4 and our pup. Started the uphill climb at a steady pace and then we hit snow! Beautiful hike, a little sketchy losing the trail at times but we made it to a snow packed campground before sunset. Can't wait to go back.

Thanks for the information John. I am probably going to have to consider this a problem for our trip. A group of us (6) were planning to go, and though it might be safer together, I'm still concerned about this.

I can confirm Kevyn's information regarding this trail. I was just up there this weekend, and with snow on the trail, it was nothing but one big icy slope with 0 definition of where the trail was; I turned around within the 1st mile. James, it gets steep about a half mile into the hike. I have not seen the trail in good weather conditions, but with snow, I had no idea where the trail was after a half mile. I hiked a little bit further to see if it would become better defined and it didn't. I was just walking on a slope ... so glad I turned around.

Look at Kevyn's picture. That is exactly what I experienced.

Kevyn or any experienced hikers on this trail: can someone tell me where it gets steep, especially in the snow? I have a trip planned for an overnight there; my thought is if we take the PCT trail until we get to the Little Jimmy Road, we shouldn't run into the dangerous steep sections Kevyn was referring to. Are these located on the PCT trail AFTER the Fire road intersection?

Thanks Kevin for the review. I was thinking boing to go up.

If this is your first time hiking this trail PLEASE read my review first. I am a VERY experienced hiker and just last week I decided to hike this trail to set up camp at little jimmy. This is one of the most beautiful trails I have hiked, but also the most dangerous. At about mile 3-4 the trail is incredibly icy with a very vertical drop off to your left. I went as slow as I could and slipped off the side and fell neck deep into snow. I had to bail all of my gear to get out and then had no cell phone signal to call for help. Spent the rest of the night hiking down in freezing conditions. I was lucky to come back from this hike and do NOT attempt this hike without crampons and an ice axe. If you slip you will be at the mercy of the mountain. I am thankful to come back from this hike, please take my advice!

The view from the top is about as good as it gets. Didn't want to leave the place once I finished. Also managed to spot 5 rams heading down. Plan on coming back early spring!

Always a favorite! Scenic, beautiful trail. A little rough the first mile but a piece of cake thereafter all the way to the top of Mt. Islip. My two boys, under 13, do this trail with me.

I've hiked over three dozen trails in the Angeles National Forest, and this is one of the most scenic. The path I took to the summit was a little different from the route on the AllTrails map, though. After relaxing at Little Jimmy Campground, I continued south on the Pacific Crest Trail, which is located on the southeast side of the camp (the map on AllTrails instructs you to take a path on the southwest side). The PCT passes by Little Jimmy Springs and leads to the junction at Windy Gap. It's a worthwhile detour, as the view from Windy Gap of Mt. Hawkins and Crystal Lake area is stunning. I then headed west up to Mt. Islip, passing by the trail that leads back to Little Jimmy Campground.

When you park in the lot, it might be tempting to take the trail labeled Islip Saddle, but I learned that the trail to the peak is actually located just across the highway!

I'm always excited when I get to hike a section of the PCT, and this was a rather lovely one! The first 15 minutes of the hike were a bit rough. I was out of breath fairly quickly, but I think I can attribute that to the elevation. The rest of it was quite manageable.

Most of the hike is in the shade of some big trees, making it a perfect summer hike. It really feels like you're in a forest.

I hesitate even reviewing this trail. Mt Islip and CLJ are one favorite Los Angeles based hikes and campgrounds.

Part of the PCT Mt Islip is a section of trail offers views, wildlife, plant life and different environments as you trek. This trail is rated moderate in difficulty however it is the elevation that may be more of an obstacle for some who are not use to it. Take your time up the mountain where you will be rewarded with views looking over primarily LA & OC counties and stretching past Catalina Island. A top of Islip is also an old cabin built in the twenties that is still standing.

The hike is approximately 3.5 to 4.5 hours and approximately 6+ miles. Plan on carving out 8 hours with drive time from LA area.

- Most of this hike is on the north face of the mountain. Plan accordingly.
- Water available at LJS.

Great camping spot. Many sites to choose from. Little jimmy springs not too far, so there is plenty of water. Did the hike to Islip the next morning. Great views

Hiked this trail on a Friday. The trail starts with about a 1/10th of a mile steep incline as you leave the parking lot at Islip Saddle. After reaching the top of the hill, the incline becomes much less steep for the remainder of the first mile. 2nd mile is almost flat and drops you off at the Little Jimmy Campground. After entering the campground, turn right and go past the wooden outhouse in order to continue on up to Mt. Islip. A nice cool breeze will greet you when you get close to the ridge. Wonderful views of the Crystal Lake Campground below when you get to the ridge. Very enjoyable hike.
(See North Route 1 under the Alternate Routes section).
